Abstract and Figures

This paper is designed to provide comprehensive details on the carbon markets across the major Asian economies and with specific attention to the Chinese carbon market. We particularly discuss the carbon markets across the major northeast (the People’s Republic of China [PRC], Japan, and the Republic of Korea) Asian economies. Further, we empirically explore the interrelationship between the Shanghai and Shenzhen carbon emission markets, using an autoregressive distributed lag (ARDL) model with daily high-frequency data from 3 January 2017 to 9 October 2018. The evidence from the analysis confirms unidirectional influence from the Shanghai carbon emission market on the Shenzhen carbon emission market. Our findings shed light on the carbon emission markets’ policy formulation for the Chinese government to achieve sustainable economic growth and meet carbon reduction targets in the PRC. Finally, we provide numerous policy and practical implications for the Asian economies with respect to the issues of climate change policies.

The Growth of Carbon
Markets in Asia:
The Potential Challenges
for Future Development
Yukun Shi, Sudharshan Reddy Paramati, and Xiaohang Ren
5.1 Introduction
Over the past 20 years, academia and industry practitioners have
persistently paid a lot of attention to studying how to eciently address
global climate change and decrease carbon emissions. Historically,
emission trading programs are widely believed to have played a
prominent role in environmental policy, especially to reduce carbon
emissions. As a result, many regional and national carbon trading
markets emerged, including the Regional Emissions Trading Scheme
in Australia, the People’s Republic of China (PRC), New Zealand, the
Republic of Korea (henceforth Korea), and the United States, and most
notably the Emissions Trading System set up by the European Union
(EU ETS). As far as we are concerned, to date the EU ETS is the major
emission cap-and-trade trading program across the world, accounting
for about $175 billion a year. The history of the EU ETS can be traced
back to 2005; today it allocates tradable emissions permits to more than
12 large power stations and industrial plants in more than 20 countries,
accounting for about half of the EU’s total greenhouse gas (GHG)
emissions in aggregate.
Previous research focused on the impacts of energy, financial
markets, and macroeconomic factors on the EU carbon emission market
(see, for instance, Alberola et al. 2008, Chevallier 2009, Koch 2014).
However, to the best of our knowledge, fewer studies have focused on the
relationship between the carbon emission markets of the PRC and the
EU. As the PRC is the largest GHG emitter, its government has given a lot
126 Ways to Achieve Clean Asia
of attention to setting up carbon trading markets, such as the Shanghai
and the Shenzhen carbon emission markets. Therefore, the growth of
carbon emission markets in the PRC has raised the question: What is
the relationship between regional carbon emission markets? Moreover,
the lessons from the linkages between regional carbon emission markets
could help enhance the carbon emission market cooperation both in
the PRC and around the world and provide additional insight for other
developing countries into the domestic emissions trading system (ETS).
Our main empirical findings suggested the existence of co-integration
between the futures prices in PRC’s carbon emission markets. In
particular, the Shanghai carbon emission market positively aects the
Shenzhen carbon emission market, but a similar vice versa relationship
could not be found. Our findings shed light on the policy formulation
of the carbon emission markets for the PRC government to achieve
sustainable economic growth and meet the carbon reduction targets of
the country.
Since the well-known economic revolution that started in the late
1970s, the economy of the PRC has undergone decades of significant
developments and became the second-largest economy in the world
in 2016, according to the World Bank’s data on gross domestic product
(GDP) at the end of 2017. Despite its undebatable economic success,
a side eect of PRC’s economic progress is the unprecedented large
volume of carbon emissions. As a result, the National Development
and Reform Commission issued “interim measures for voluntary
GHG emissions trading management” in June 2012 to explore the
possibility of a voluntary emissions trading program in the PRC. This
is the country’s initial attempt to reduce carbon emissions and has been
generally regarded as a signal to the public. It lays out the theoretical
foundation for further practical implementation of mandatory carbon
trading mechanisms as well as the establishment of carbon emission
rights exchanges in Shanghai, Shenzhen, and other places in the PRC.
As a matter of fact, the first carbon emission exchange in the PRC was
set up in Shenzhen in June 2013, and Shanghai and other places had
followed suit by the end of November 2013. These have since become the
two most important carbon emission exchanges in the PRC, parallel to
the two most important stock exchanges in the country in Shanghai and
Shenzhen. Given the current prominent status of the PRC’s economy, a
significant reduction in the level of carbon emissions of the PRC stock
market will be expected from these programs.
In theory, the establishment of carbon emission markets will
significantly decrease the level of carbon emissions of the country,
which has milestone implications for its carbon emission reductions. In
practice, however, there was a trivial volume before 2007. To date, to
The Growth of Carbon Markets in Asia: The Potential Challenges for Future Development 127
the best of our knowledge, no paper has discussed the interrelationship
among the futures prices in multiple carbon emission exchanges in
the PRC. However, a large strand of literature has already discussed
the interrelationship between the stock prices in the Shanghai and
Shenzhen stock exchanges. This paper aims to focus on these two most
important carbon emission exchanges. To be specific, it will examine
whether the futures price in the Shanghai carbon emission exchange
aects the futures price in the Shenzhen carbon emission exchange, and
vice versa, considering the exogenous shock mainly from the EU ETS.
This paper will contribute to the existing literature in the following
three ways: First, it is the first to investigate the dynamic linkage of the
futures prices between these two markets. The study results will shed
light on the interrelationship of the futures prices in these two markets
and provide risk management guidelines for the two markets’ investors.
Second, this study applies daily high-frequency data from 3 January 2017
to 9 October 2018. An investigation into the futures price on a lower-
frequency level cannot capture the dynamic influence, while intraday
high-frequency data will suer from much misconstruction noise in this
study. Third, we introduce the autoregressive distributed lag model to
this topic, which integrates short-run adjustment eects with long-run
equilibrium without losing information (see Jalil and Feridun 2011).
5.2 Background
Since the emergence of the EU ETS in 2005, the carbon emission market
has emerged to become a prominent system for mitigating climate
change across the globe. Countries of the Association of Southeast Asian
Nations (ASEAN) have focused their attention on this modern and
global idea of mitigating climate change, having noted the rate at which
emissions continue to increase in the region. Northeast Asian countries
such as the PRC, Japan, and Korea contribute more than one-fifth of
the world’s GDP and more than a quarter of global emissions (Ewing
2016a). Equally, the increase in emissions in Southeast Asia is almost
sprinting forward at the same rate as its economic growth, with nearly
a 5% annual increase from 1990 to 2010 (Raitzer et al. 2015). This surge
has been traced to the relative escalation of emissions in sectors such
as manufacturing and transportation. These two sectors are associated
with the region’s structural change rather than rural or agrarian areas.
There is, therefore, an urgent need to curtail the increase in
emissions, owing to the fact that emissions cause much harm to humanity
and the economy as a whole. Given that, the global carbon finance
needs to be upheld by an order of “weight-carrying” in the second
commitment period of the Kyoto Protocol. To enable the stakeholders in
128 Ways to Achieve Clean Asia
the carbon market to see the opportunities far away, outside the project-
based Clean Development Mechanism (CDM), alternative schemes,
such as allowance-based market mechanisms, may be considered in
the emerging economies in a similar manner to the one that functions
in Europe, i.e., the EU ETS (Grubb 2012, Perdan and Azapagic 2011).
Evidently, there has been significant progress in this market as the trend
has gained popularity among the major Asian economies, including
the PRC, India, Japan, Kazakhstan, and Korea. The PRC, which is the
world’s major growing market, is expected to have a greater potential
for the scale of carbon trading (Jotzo et al. 2013, Wang 2013, Fankhauser
2011, Guan and Hubacek 2010).
Based on the above, we see clearly the significance of carbon
emission mechanisms, which are considered popular instruments in
the domestic and international circuit for enhancing eorts toward
mitigating climate change. These instruments often put a price tag
on emissions that lead to climate-damaging GHGs, which eventually
leads to the promotion of climate change mitigation eorts. More
specifically, two approaches led to the creation of carbon markets,
i.e., the cap-and-trade mechanism and the carbon tax mechanism
(Hartmann 2017).
Cap-and-trade mechanism. The cap-and-trade mechanism is
used by governments or intergovernmental bodies to peg a limit to
GHG emissions in a given period. This mechanism is designed to oer
licenses to both companies and industries to minimize the growth of
pollution (Stavins 2008). The scheme is designed in such a way that if
companies that do not meet their cap buy licenses from others, they will
have a surplus. The technicality here is that it provides an opportunity
to reduce GHGs with a cost-eective platform. However, it is also
widely criticized because it rewards most polluters with windfall profits
while undermining the eorts to reduce pollution and achieve a more
sustainable economy.
Despite this criticism, its popularity remains high, going by the wide
range of potentials, which can engender considerable revenues. These
collected revenues have significant implications for distribution in the
spirit of fairness and economic growth. The possible uses of carbon
revenues could include: (i) counterbalancing the unequal eects of high
energy prices on low-income households in the form of discounts on
electricity bills; (ii) providing transitional assistance (e.g., arranging
or providing financial support for job training) for communities and
individuals whose livelihood depends on fossil fuels; (iii) providing
financial support for communities that face an unequal burden from
carbon emissions from fossil fuels; and (iv) investing in clean/renewable
energies, energy-ecient technologies, and clean vehicles, which all
The Growth of Carbon Markets in Asia: The Potential Challenges for Future Development 129
play an important role in moving the economy from a carbon-intensive
to a clean-energy economy.
In addition, cap and trade in the form of ETSs has progressed faster
and attracted the attention of policy makers and practitioners since
the emergence of the EU ETS in 2005. For instance, in 2014, 18 ETS
programs were initiated across 18 national and subnational jurisdictions.
This initiation was planned for one more country and was also being
considered for implementation in 11 more national and subnational
jurisdictions (World Bank 2014). Subsequently, the implementation and
planning of ETSs spread across all regions except in Africa. The ETSs
also covered nearly 9% of global GHG emissions by 2015. Before 2015,
the World Bank (2014) documented that the majority of implemented
ETS programs have made landslide achievements in recent years in
terms of scope, linkages, and development of approaches. To this end,
the cap-and-trade mechanism could be said to be gaining ground
among European, Asian, and North American countries. Hopefully, this
may also potentially spread to other regions such as sub-Saharan Africa
and Africa.
Carbon tax mechanism. Carbon tax is another mechanism used to
curtail excessive emissions around the world. Carbon tax is a form of
tax whereby each unit of GHG emission gives participating firms (and
households, depending on the scope) an incentive to reduce pollution
(Taschini et al. 2013). Hence, the rate of pollution is reduced, depending
on the chosen level of tax. For these reasons, carbon tax could be assessed
by considering the cost or damage associated with each unit of pollution
and the cost associated with controlling that pollution. Therefore, getting
the tax level correct is the key, even though some firms and households
will most likely opt to pay the taxes, while continuing to pollute the
environment, beyond and above what is optimal for society. If the level
of pollution is high, then the cost will rise higher than necessary to
reduce emissions, and it will have a considerable impact on profits, jobs,
and end-use consumers.
It is also important to highlight here that carbon tax can cause an
increase in business overheads. In this case, companies will be pushed
to find ecient ways to manufacture their products and/or deliver their
services, as this would be beneficial to their bottom-line users. This
idea supports more environment-friendly and creative ideas among
industries. Furthermore, carbon emissions have also been linked to
worsening public health as they have a major impact on the quality of
the air we breathe. However, implementing a carbon tax could improve
air quality by reducing carbon emissions, thereby decreasing the rate
of respiratory issues and the number of asthma attacks (Kramer and
Fraser-Hidalgo 2018).
130 Ways to Achieve Clean Asia
Based on the above, many countries have demonstrated knowledge
of carbon trading via various approaches hinged on the flexibility of
carbon taxes to fit into national circumstances. For instance, in 2014,
over 14 countries implemented carbon tax approaches to fight or reduce
the level of emissions in their countries. Some of these countries took
various approaches in the light of national circumstances (to enable
the use of carbon taxes together with other carbon pricing appliances),
while others turned toward approaches that considered industry
competitiveness (World Bank 2014).
On the other hand, politicians around the world favored the use of
the carbon trading option over the second option, carbon tax. This is
because in the carbon trading scheme, each participant firm is given
a certain emission allowance quota in the primary ETS market, and
then trades with other members in the secondary ETS market for
extra allowance to support its ongoing production or for benefits if the
permitted quote is not used (Tang et al. 2016, Zhang et al. 2015). Usually
in the initial stages of trading, the emission allowance quota is either
given to businesses for free or sold at auction. Therefore, over time
the number of existing permits decreases, putting more pressure on
participating firms to invest more money in production technologies to
reduce the growth of carbon emissions. Hence, this approach will help
firms to come up with more innovations, which will significantly assist
them in reducing the price of new technologies.
5.3 The Growth of Carbon Markets in Asia
Since 2015, the issue of climate change has become a global agenda as
many eorts have been made to meet the Paris Agreement. Specifically,
the participating countries are dedicated and prepared to address the
climate change issue through various means. To date, 175 countries
around the world have ratified the agreement, including, among other
Asian countries, countries in Northeast and Southeast Asia (Ewing
2016a). This section seeks to explore the current status in the Asian
region, particularly in the major economies of Northeast Asia. To
address the increasing concerns around the issue of climate change,
the major economies in Northeast Asia have developed carbon markets.
The growth of carbon markets has been very impressive in the last few
years. More specifically, the number of carbon markets has doubled
since 2012 and the general interest in carbon trading is also on an
upswing. Further, emission pricing is worth $50 billion (Ewing 2016b).
In the following, we discuss three major Northeast Asian economies:
the PRC, Japan, and Korea.
The Growth of Carbon Markets in Asia: The Potential Challenges for Future Development 131
The PRC. The main objective of the Kyoto Protocol is to address the
issue of climate change by introducing a proper market mechanism. It
has been noted in the recent past that the international carbon market is
growing rapidly and is well diversified across various forms of markets,
such as the CDM, voluntary emission reduction, and emission allowance
trading. The PRC is not an exception, as it has challenged itself to build
a more formidable carbon market, having realized the volatile nature of
an economy in which carbon emissions are at an extreme level due to
industrialization. As a result, in 2011 the PRC pledged its support toward
promoting low carbon emission development through carbon trading
where the set target of energy consumption per unit of GDP would drop
by 3.4% in 2014 and 2.32% in 2015 (The Economist 2015). By the end of
September 2017, the market had covered 3,000 entities from more than
20 industry sectors, with the total trading volume reaching 200 million
tons of CO2 equivalent (tCO2e) while the total trading value was about
45.1 billion yuan (CNY) and the price ranged from CNY1123 /tCO2e
(EDF 2017). This therefore indicates that the carbon markets in the PRC
are gaining momentum and moving toward achieving a low-emission
economy.
As an addendum to the above, huge successes have been recorded in
the reduction of carbon emissions (mainly in the power sector) with an
estimated 0.09 billion tCO2e dierence when compared to the level of
2016. Fossil fuel power generation will reach 4.88 kWh with an average
eciency of 305 gce/kWh by 2020. By contrast, in 2016, non-fossil fuel
power generation increased 0.06 trillion kWh, and this is expected to
decrease to 0.51 trillion tCO2e by 2020 (EDF 2017). This, therefore,
implies that the PRC adopted all carbon mechanisms to achieve its
slated plan.
In the ongoing eort to achieve a stronger carbon market, the PRC is
establishing strong collaboration with other international counterparts
with respect to carbon pricing. For instance, in October 2017, both the
PRC and the EU declared continued collaboration on emissions trading.
On this platform, the EU agreed to continue to support the PRC develop
its national ETS for 3 years (EU 2017). In addition, on 4 December
2017, the PRC and Canadian governments released a joint declaration
on climate change, which basically explains their commitment to
strengthening their collaboration, particularly as regards clean energy
and carbon markets (Government of the PRC 2017).
Several researchers have also considered the price dynamics of
CO2 allowances to explain the position of emissions. Some authors
argue that the PRC’s carbon market is competent. Tang et al. (2017),
for example, oered a multi-agent-based ETS simulation approach to
132 Ways to Achieve Clean Asia
test for a suitable carbon allowance auction design for the PRC’s ETS.
The authors concluded that the ETS has a substantial positive impact
on reducing emissions and improving the energy structure. However,
the authors advised that it adversely aects economic growth. Likewise,
Mu et al. (2018), using a computational general equilibrium (CGE)
framework, document that only the eight sectors planned to be part of
the initial execution of the ETS in the PRC are likely to have a much
larger mitigation cost. However, the mitigation costs can be minimized
by up to 3.3% of real GDP by 2030, but only if other prominent energy-
intensive sectors, which account for about an additional 24.8% of total
emissions, are included in the system.
Japan. The development of Japan’s carbon market can be viewed in
two dierent dimensions. First, the development of the CDM project,
which took eect in 2002–2004 with 12 projects, two of which are
being validated. The projects focus on the decomposition of carbon
emissions, and are estimated to have 4.8 million tCO2e per year
(Mizuno 2004). Secondly, the development of the Japanese Voluntary
Emissions Trading Scheme (JVETS), which was introduced in 2005
by the Ministry of Environment, Japan, and is aimed at reducing the
GHG emission activities in the Japanese companies listed under the
Keidanren Voluntary Action Plan (MOEJ 2012). As of 2012, JVETS had
389 members, which achieved a great reduction of 59,419 tCO2 in their
total emissions. It was noted that the mean trading price was roughly
¥216 ($2.60)/tCO2. In addition, the 389 companies that participated in
JVETS recorded a cumulative emissions decrease of 2,217 million tCO2e,
much higher than the planned target of 1,245 million tCO2e. JVETS
increased further to cover 0.3% of the emissions in 1990 (3.4 million
tCO2/year as observed in the fourth term) (IGES, EDF, and IETA 2016).
Studies have analyzed the ETS linking in Japan. For example,
Wakabayashi and Kimura (2018) point out that the Tokyo ETS alone
cannot reduce carbon emissions but has other factors, such as energy-
saving tools. However, Lu et al. (2013) used a multi-regional model and
found that the carbon leakage ratio in the case of full auctioning in the
ETS of Japan is not very dierent from the grandfathering and output-
based scenarios and does not reduce carbon emissions.
Republic of Korea. In compliance with the Kyoto Protocol, in May
2012 the Korean government passed the “Act on the Allocation and
Trading of Greenhouse Gas Emission Permits.” But the implementation
could not begin until 2014 with the establishment of the ETS’s simple
proposal and formulation of the First National Emission Permit
Allocation Plan. At the beginning, the Ministry of the Environment
decided to allocate about 1,598 million Korean allowance units to
525 companies for 2015 (IETA 2017). The allocation of credits was
The Growth of Carbon Markets in Asia: The Potential Challenges for Future Development 133
successfully completed in August 2016, which was part of the first phase
in the first year of compliance.
The second phase of the Korean ETS was introduced in January
2018 and will run through until 2020 with an estimated emission cap of
538.5 MtCO2 to be considered as against 0.4 MtCO2 less than the previous
year as documented in the National Allocation Plan. At the beginning of
2019, auctioning was considered in the subsectors that failed to meet
the standards for trade intensity and further production-related cost
due to the ETS. They are estimated at 3% of total volume of allowances
auctioned to these subsectors. However, the other subsectors that meet
the standards continue to obtain 100% free allocation (MOE, Republic of
Korea 2018). Basically, in the second phase, free allocation is stretched to
eight subsectors rather than the usual three subsectors, namely, cement,
refinery, and aviation. Moreover, guidelines have also been developed to
allow the use of certified emission reductions generated outside Korea
for compliance.
5.4 The Potential Challenges for the Growth
of Carbon Markets in Asia
Asia is one of the fastest-growing regions of the world. However,
the region is also responsible for a major share of global emissions,
particularly since the Paris Agreement in 2015. Therefore, in this
section, we aim to highlight the challenges that the region is facing to
address the issue of climate change without damaging its economic
development and prosperity.
Inadequate implementation of ETS policy. Adequate policy
implementation is indispensable, particularly when beginning to
establish a carbon market. The reason for this is that the market relies
heavily on it to boost outputs through its ETS policy by binding the
emission cap set to all firms that need to limit their GHG emissions,
or by controlling the number of firms based on their commitment to
reducing emissions. However, such an emission cap in the Asian carbon
market is evidently yet to be introduced. Further, it is also important to
highlight that the market demand is not strong enough to help the new
industry meet its emission reduction targets.
This may be because the Asian carbon market is still very young and
most countries in the region are in the first phase of its implementation.
In the absence of full implementation of the ETS policy, it is well
documented that most existing ETSs do not cover all sectors and only
a few major carbon emitters are included in the ETS policy (Mu et al.
2018). The ETS policy has been driven by chemicals, petrochemicals,
134 Ways to Achieve Clean Asia
iron and steel, construction materials, paper, air transport industries,
nonferrous metals, and electricity. However, the wide sectoral coverage
is to estimate the true picture of mitigation costs as compared with the
limited sectoral design, which can underestimate the mitigation costs.
Limited private financing. Financial institutions has been argued
to play an important role in the functioning of the carbon market (UNEP
Finance Initiative 2011). This does not exclude Asia, where the banking
sector plays the major financing role. However, severe capital adequacy
requirements and maturity mismatches have been attached to lending.
According to Watson et al. (2017), 18 Asian countries received a total
of $3.8 billion in climate funds from 17 multilateral climate funds and
initiatives for 422 projects and programs in 2016. Among the funds
are the PRC’s public climate fund which currently dominate the total
investment in climate finance (Wang et al. 2012). An estimated $294
billion was oered by state-owned banks in 2011 and the government
climate spending was $41 billion, while foreign and domestic bank loans
stood at $10 billion (The Climate Group 2013). Thus, this implies that
the major source of climate finance is public funds. It is also important to
highlight that the current system cannot divert private investments into
the carbon markets. However, this is in contrast to the global practice
where private investment is the major source of finance for climate
mitigation (Stadelmann et al. 2013, Grubb et al. 2011).
Lack of regulatory system. Going by international standards in
carbon-trading management systems, there should be an integrated
institutional setup in which the system takes control of regulating carbon
trading and its functioning. For instance, in the EU, the carbon-trading
management system adopted a two-level organization, which includes
central management and environmental protection departments from
the governments of members (Knight 2010). Further, it clearly specifies
the division of work, and explicitly draws a distinction between rights
and obligations. Moreover, coordination and cooperation are ensured to
achieve high eciency in the operation and management of the carbon-
trading system.
However, this is not applicable in the Asian carbon market where no
specific regulatory institution is responsible for the carbon trade setup.
Because of that, it is dicult to set up a reliable and robust monitoring
system and reporting and authentication mechanisms, which are
the backbone to the success of the carbon market in Europe. So, legal
administration is continuously a problem challenging all walks of life
in the society. Hence, we highlight the fact that currently no regional
regulatory system helps strengthen and smoothen the functioning of the
ETS and its administrative operation. Although the ETS program has
been implemented by the respective countries in the region, there is no
The Growth of Carbon Markets in Asia: The Potential Challenges for Future Development 135
harmonized system, and it is useful to review and adopt a more unified
regulatory system for the region, which will play a key role in this aspect.
Corruption, access to information, and local capacity. Most Asian
countries either operate a central economy or are transiting to a market-
driven economy. Thus, eorts to attract foreign investors are always
faced with problems of corruption and bureaucracy, including poor law
enforcement and poor infrastructures, all of which may impact the ease
of doing business generally and the execution of CDM projects in these
countries. In addition, information on CDM potentials is paramount
in the carbon market because it enhances the viability of the market.
However, this information is often not accessible. For example, Nguyen,
Sousa, and Uddin (2010) argued that national potentials of renewable
energy resources have not been investigated and are often not available
to users. As such, investors and developers are deterred from investing
in the Viet Nam carbon market. As these barriers continue to linger, the
awareness of CDM potentials among enterprises, the private sector,
public entities, and nongovernment organization is limited.
5.5 Evidence from Previous Studies
We can reasonably divide the existing international literature on carbon
emission markets into two segments. One strand of the literature has
analyzed the interactions between carbon and energy markets (see, for
example, Mansanet-Bataller et al. 2007, Alberola et al. 2008, Fezzi and
Bunn 2009, Hintermann 2010). These authors find that energy prices—
i.e., prices of oil, gas, coal, and electricity—are important driving factors
for carbon futures prices of the EU carbon emission market in phase I.
Bredin and Muckley (2011) investigate the association between carbon
and energy prices in phase II using a co-integration method. Using the
Dynamic Conditional Correlation GARCH model, Koenig (2011) and
Chevallier (2012) provide evidence on the dynamics of correlations
between carbon and energy markets.
Another strand of the literature examines the theoretical and
empirical link between the carbon and financial markets. For example,
Daskalakis, Psychoyios, and Markellos (2009) find significant negative
links exist between the EU carbon emission market and equity market.
Gronwald, Ketterer, and Trück (2011) employ the copula method and
find a significant dependence between carbon and stock markets. Koch
(2014) considers a multivariate GARCH model to analyze the price
interactions among the carbon, energy, and financial markets.
According to the seminal review paper by Babatunde, Begum, and
Said (2017), there has been an increasing interest recently in investigating
the climate change mitigation policies of the PRC, especially among
136 Ways to Achieve Clean Asia
academia. Research related to the PRC can be safely divided into three
strands, according to the specific aspect the strand focuses on: (i) the
reduction of CO2 emission intensity, (ii) the development of renewable
energy, and (iii) estimation of the emissions peak.
A vast strand of literature tries to investigate the impact and
evaluation of the PRC’s carbon intensity targets, especially using CGE
models. In a notable proportion of this strand of literature, various
optimization methods have been used to look for the optimal mitigation
cost path given some carbon intensity targets, treating these targets as
emission constraints. In the short run, a noteworthy example is Zhang
et al. (2013), who simulated the statistical and economic influences of
the PRC’s national emission intensity targets over the sample period
of 2010–2015 for the 12th National Five-Year Plan. To their surprise,
they can only identify a considerable welfare loss, which ranges from
about 1.2% to 1.5% via dierent disaggregation technologies of reduction
targets among various Chinese provinces. In contrast, Dai et al. (2011)
identified a much smaller (if not trivial) impact. According to the PRC’s
Copenhagen commitment, compared with its 2005 level, the PRC will
try to reduce its national CO2 emissions intensity by 40%–45% before
the end of 2020. Dai et al. (2011) concluded that even in the extreme
case where the PRC has successfully fulfilled its commitment (which
is unlikely given the current situation that its carbon emissions were
relatively high by the end of 2016), the PRC’s national GDP loss would
only range from about 0.032% to 0.24%.
In the long run, Wang, Wang, and Chen (2009) tried to gauge the
economic impact of the PRC’s long-term emission reduction scenario
up to 2050. In contrast to the extant literature, they argued that foreseen
and unforeseen technological innovations may, to some extent, promote
economic growth in the PRC, improve the energy eciency in the
country, and reduce the carbon intensity there. At the same time, Qi et
al. (2016) also simulated a long-term scenario for the PRC from 2020
to 2050. They assumed a 3% average annual reduction in CO2 intensity
over their sample period, and found that the associated national welfare
loss in the PRC would be only 0.9% in 2030, which would increase to
1.6% in 2050. Considering the possible international/national/regional
design of the associated carbon ETS in the future, other papers have also
tried to gauge the economic impacts of carbon intensity targets in the
PRC and obtained dierent results. For instance, assuming the existence
of a counterfactual global carbon emission market, both Zhang et al.
(2017) and Qi and Weng (2016) attempted to gauge the economic impact
of the PRC’s emission targets by the end of 2020 and 2030, respectively.
At the same time, using the sectoral approach as a complement,
Mu, Wang, and Cai (2017) went one step further and argued that the
The Growth of Carbon Markets in Asia: The Potential Challenges for Future Development 137
international Intended Nationally Determined Contributions (INDC)
could help achieve the committed emission reduction target without
suering from statistically significant economic loss. Focusing on one
province, Guangdong, and assuming that the PRC would fully achieve its
Copenhagen commitment, Wang et al. (2015) attempted to quantify the
economic impacts of the ETS in Guangdong, one of the most developed
provinces of the PRC, by the end of 2020. At the same time, focusing on
Shanghai city and assuming the PRC’s INDC commitments will be fully
achieved by the end of 2030, Wu et al. (2016) performed an empirical
analysis similar to that carried out by Wang et al. (2015). Both Wang et
al. (2015) and Wu et al. (2016) identified a negative economic influence
in the PRC brought about by achieving the PRC’s emission reduction
targets, and provided evidence that the carbon ETS can help mitigate
the associated costs when the PRC moves toward its carbon emission
reduction target.
Another strand of literature focuses on the social, economic, and
environmental impacts of the development of renewable energy in the
PRC, especially in the last couple of decades. A notable example is Qi,
Zhang, and Karplus (2014), who conjectured that the carbon emission
reduction will not be substantial, despite a possibility of many additional
renewable power installations in the second decade of the 21st century.
Focusing on the impact on the employment rate, Cai et al. (2014) found
empirical evidence that more and more jobs would be created due to
the development of renewable and/or new energy in the PRC from
the second decade of the 21st century. Interestingly, Dai et al. (2016)
successfully found more encouraging evidence that carbon emissions
would be reduced without incurring substantial macroeconomic costs
due to the large-scale development of renewable energy in the PRC.
Considering the synergy between emission control and renewable/
new energy, Mittal et al. (2016), Cheng et al. (2016), and Duan et al.
(2016) provided more armative evidence that both the targets of
carbon emission reduction and the development of renewable/new
energy in the PRC may be achieved at the same time without too much
macroeconomic costs.
To sum up, the extant literature up until now has already
documented a range of evidence on the ongoing smooth low-carbon
transition of the PRC economy, and most of the evidence is encouraging
for both economists and policy makers. However, there is still a gap in the
literature, which is the interrelationship among the newly established
regional carbon emission exchanges in the PRC, especially considering
the exogenous impact from the well-established carbon emission
exchanges from outside the PRC. Therefore, we are conducting this
project to investigate the potentially existing interrelationship between
138 Ways to Achieve Clean Asia
arguably the two most important domestic carbon emission exchanges
in the PRC, considering the probable exogenous impact from the
influential European ETS.
5.6 Data and Methodology
5.6.1 Data
This section describes the data in detail. The data set consist of daily
prices for the carbon emission markets of the EU1, Shanghai (SH), and
Shenzhen (SZ)2 over the period of 3 January 2017 to 9 October 2018,
since trading volumes in the Shanghai and Shenzhen carbon emission
markets were trivial before 2017. All commodity prices are expressed in
CNY. Figure 5.1 shows the time series plot for the closing prices in both
the Shanghai and Shenzhen carbon emission markets in terms of daily
frequency. According to Figure 5.1, there are enough sample variations

for both the Shanghai and Shenzhen carbon emission markets over
our sample period in our data set. Interestingly, the Shanghai carbon
emission market has no clear time trend, while that of Shenzhen shows a
declining time trend to some extent. We present the summary statistics in
Tables 5.1 and 5.2, which further supports our previous observation that
there are enough sample variations for both the Shanghai and Shenzhen
carbon emission markets over the sample period in our data set.
140 Ways to Achieve Clean Asia
To begin our investigation, it is necessary to test the“stationarity
of the variables used in this analysis. To determine the order of the
“stationarity” of these series, we consider both the Augmented Dickey-
Fuller (ADF) and Phillips-Perron (PP) unit root tests. The results in Table
5.2 show mixed findings. The null hypothesis that there is a unit root in
levels cannot be rejected for the EU and SH markets but not for the SZ
market at 1% significance level. However, the null hypothesis that there
is a unit root in levels is strongly rejected at the 1% significance level for
all variables when they are applied to the first-order dierences. These
findings indicate that our variables have a mixed order of integration
and that EU and SH are I (1) and SZ is I (0), which makes our empirical
analysis more dicult and hinders many common econometric tools in
this project.
5.6.2 Methodology
One aim of this study is to investigate the relationship between the
PRC’s carbon emission markets, and between those of the EU and the
PRC. Due to the mixed order of integration of our data, we employ
the autoregressive distributed lag (ARDL) approach (see, for example,
Pesaran et al. 2001) to investigate the impact of the EU carbon emission
market on those of the PRC. The ARDL model assumes that the
dependent variable is a function of its own past lagged values as well as
current and past values of other explanatory variables. For the model,
the sample series do not have to be I (1) (see, for example, Pesaran
and Pesaran 1997). In addition, the ARDL model in conditional error
correction form can integrate short-run adjustment eects with long-
run equilibrium without losing information (see, for instance, Jalil and
Feridun 2011). Therefore, we can get more information, especially in
terms of ecient co-integration relationships, by using this approach
(see, for instance, Ghatak and Siddiki 2001). The ARDL (p, q) model can
be specified as follows:

where t = max(p,q,r),,T. The optimal lag orders p, q, and r can be
obtained by minimizing the conventional Bayesian information criterion
(BIC). For most cases, we find that the optimal number of lags is t = 1,
which we use in the analysis. As a result, we restrict all of them that
equal one to reduce the noise introduced by the optimal number of lags,
and make sure that each term is on the same page.

. In these two formulas above, the shortened forms SH,
SZ, and EU stand for futures prices in the Shanghai, the Shenzhen, and
the EU carbon emission markets, respectively. These forms of equation
provide us with an opportunity to look into both the short-run and long-
run relationship at the same time. It is also feasible to include more
control variables if necessary.
5.7 Empirical Results and Discussion
This section presents the results obtained via the model specified in
the previous section. We will empirically examine the impact of the
EU carbon emission market on the PRC’s carbon emission markets.
The main results of our ARDL model are displayed in Tables 5.3 and
5.4. Several conclusions can be drawn from these two tables. The most
important is perhaps that on the interrelationship in the long run as
indicated below:
• According to Panel A in Table 5.3, a 1% growth in the futures price
in the Shanghai carbon emission market increases the futures
price in the Shenzhen carbon emission market by 0.5502% in the
long run, which is strongly statistically significant at the 5% level.
• According to Panel A in Table 4, a 1% increase in the futures
price in the Shenzhen carbon emission market raises the futures
price in the Shanghai carbon emission market by 0.4330% in the
long run, which is only marginally statistically significant at the
10% level.
The above findings indicate that there is a (at least unidirectional)
long-run relationship between the Shanghai and the Shenzhen carbon
142 Ways to Achieve Clean Asia
emission markets. More specifically, the long-run results for the
Shenzhen carbon emission market (Panel A in Table 5.3) show that the
Shanghai carbon emission market plays a substantial role in promoting
the futures price in the Shenzhen carbon emission market, which is
generally positive as expected. In contrast, the EU carbon emission
market is not found to have a statistically significant long-run impact
on the Shenzhen carbon emission market. However, the long-run
results for the Shenzhen carbon emission market (Panel A in Table 5.4)
reveal that the Shenzhen carbon emission market is not a statistically
significant determinant of the Shanghai carbon emission market at the
conventional 5% significance level.
To our surprise, the long-run impact of the EU carbon emission
market on the Shanghai and Shenzhen carbon emission markets is
also not statistically significant at the conventional 5% significance
level. To be specific, for the Shenzhen carbon emission market, the
estimated coecient for InEU is –0.0262 with a p value of 0.2956 in
Panel A of Table 5.3. For the Shanghai carbon emission market, the
estimated coecient for InEU is 0.0035 with a p value of 0.9202 in
Panel A of Table5.4.

The Growth of Carbon Markets in Asia: The Potential Challenges for Future Development 143
The short-run coecients are shown in Panel B of Tables 5.3 and
5.4. The short-run impact of the EU carbon emission market is also not
statistically significant on either Shanghai or Shenzhen carbon emission
market at the conventional 5% significance level. To be specific, for
the Shenzhen carbon emission market, the estimated coecient for
InEU is –0.0349 with a p value of 0.3760 in Panel B of Table 5.3. For the
Shanghai carbon emission market, the estimated coecient for InEU
is –0.0109 with a p value of 0.5733 in Panel B of Table 5.4. The reason
may be due partly to the characteristics of regional trading for carbon
emission markets in the PRC, which lead to the strong link between the
Shenzhen and Shanghai carbon emission markets, and the insignificant
impact of the carbon emission market of the EU on that of Shenzhen
and Shanghai.
The short-run coecients for the key variables are not statistically
significant at the conventional 5% significance level, which indicates
that the short-term fluctuations in the Shenzhen and Shanghai carbon
emission markets are irrelevant to each other. To be specific, for the
Shenzhen carbon emission market, the estimated coecient of InSH
in Table 5.3 is –0.0483 with a p value of 0.3270 while for the Shanghai
carbon emission market, the estimated coecient of InSZ in Table5.4

is 0.0035 with a p value of 0.8831. Moreover, in both equations, the
estimated coecient of the error correction term (i.e., ecm[−1] in Tables
5.3 and 5.4) is negative and statistically significant at the 1% level. To
be specific, the estimated coecient of ecm(–1) is –0.1102 and –0.0498
in Tables 5.3 and 5.4, respectively. This negative estimated coecient
of the error correction term implies the speed of adjustment at which
a dependent variable returns to equilibrium following a change in the
long-run equilibrium relationship (see, for example, Sari et al. 2008).
What is more, the results show that the futures price in the Shenzhen
carbon emission market, with a larger (in absolute magnitude) estimated
coecient of the error correction term (i.e., ecm[−1] in Tables 5.3 and
5.4), has a faster adjustment rate than the futures price in the Shanghai
carbon emission market.
Given the above findings, we argue that no significant short-run
relationship exists between the Shanghai and Shenzhen carbon emission
markets, but they will influence each other from the standpoint of
their long-run relationship. Hence, we suggest that policy makers and
government ocials enhance the long-term carbon emission market
cooperation and linkage in the PRC to progressively deepen the domestic
emissions trading system.
Finally, we explore the short-run causalities between the futures
prices in the Shanghai and Shenzhen carbon emission markets using
the Granger causality test. The results of these short-run causalities
are shown in Table 5.5. The research results indicate that no reverse
causality exists between the Shanghai and Shenzhen carbon emission
markets at the conventional 5% statistical significance level. However,
there is a bidirectional relationship between the Shanghai and Shenzhen
carbon emission markets at the 10% statistical significance level. For

Note: This table reports the short-run Granger causalities using one lag in the estimation. We use *, **, and

Source: vice versa. Finally, to our surprise, in both the long run and short run, we find that the futures prices
in the EU ETS market very insignificantly impact the futures prices in both the Shanghai and Shenzhen
carbon emission markets. [PLEASE CHECK SOURCE, THANK YOU]

instance, the p value for rejecting the null hypothesis that the futures
prices in Shenzhen do not Granger-cause the futures prices in Shanghai
is 0.06766, while the p value for rejecting the null hypothesis that the
futures prices in Shanghai do not Granger-cause the futures prices in
Shenzhen is 0. 05761.
These findings have three important implications. First, our results
shed light on the policy formulation of the PRC government on the
carbon emission markets to achieve sustainable economic growth and
meet carbon reduction targets. Second, our results suggest that the
carbon emission markets are, to a very large extent, segmented at the
international level; this calls for international cooperation in terms
of reducing carbon emission targets. Third, the identification of a
significant long-run relationship, but only a marginally significant short-
run relationship, suggests that even at the national level the domestic
carbon emission exchanges in the PRC are to some extent segmented.
This suggests that a unified carbon ETS should be put into eect as soon
as possible.
We have to admit that this study has some limitations. Ideally, we
should have relied on a well-accepted economic theory to investigate
the interrelationship between the Shanghai and Shenzhen carbon
emission markets. Without such a theory, we propose using an ARDL
model with daily high-frequency data from 3 January 2017 to 9 October
2018. The choice of carbon emission exchanges is somewhat arbitrary,
as we simply choose arguably the two most famous ones, in parallel to
the well-established stock trading exchanges in the PRC. Of course,
more exogenous variables may be added. However, we doubt that our
key results will change, due to the robust nature of our methodology.
We believe that it is a fruitful research direction and leave it for future
projects.
Further, we make several policy recommendations regarding the
ecient functioning of the ETS in Asia with special reference to the
PRC, due to its significant contribution to global emissions. More
specifically, we suggest that there are several barriers in the Asian
region, particularly the little support for the carbon market. Therefore,
it is important to establish a strong regulatory system that should aim
to strengthen and support the functioning of the ETS in the region, and
perhaps across the major economies. Policy makers and government
ocials should also give considerable attention to encouraging private
investments into the carbon market. There is also a need to support
public–private partnership investments into clean energies and energy-
ecient technologies, which will have a greater impact on climate
change management (Kutan et al. 2018, Paramati et al. 2016, Paramati
146 Ways to Achieve Clean Asia
et al. 2017). Policy makers, with the cooperation of governments,
should aim to improve the functioning of the bureaucracy, particularly
the departments directly and indirectly linked with climate change
initiatives. All these additional policy initiatives will have a greater
impact on the functioning and performance of the ETS in the region,
as well as in the PRC.

... On the Asia level, Japan, China, and South Korea have established their own carbon market in compliance with the Kyoto Protocol. In 2005, Japan introduced a Japanese Voluntary Emissions Trading Scheme (JVETS) as part of its Keidanren Voluntary Action Plan to reduce the GHG emitted by the Japanese companies [10]. It resulted in a cumulative emissions decrease of the total 389 companies that participated in the JVETS. ...

Peatland fires and deforestation are prominent environmental issues in Indonesia due to industrial and plantation activities. The Indonesian government is pressured to take mitigation measures to overcome the issue since there are legal obligations to do so. One of the climate mitigation strategies is by establishing a carbon market in which the entities will be assigned certain ‘permits’ on how much greenhouse gases (GHG) emissions can be emitted, and when they have exceeded their ‘permits’, they are allowed to buy ‘extra permits’ from the other entities who still have the spare. This market has been adopted by the European Union (EU) and other countries in Asia. Therefore, this paper aims to introduce the carbon market concept by taking into account its implementation in the EU, as well as analyse how the market can become one of the climate mitigation policies in Indonesia. The research uses a doctrinal methodology that involves an in-depth legal analysis of the regulatory framework related to the issue. The authors found that the market will enhance the REDD+ Project and projected to bring revenues. However, there are challenges due to the absence of technology and the number of stakeholders involved.
... Shi et al. in their article discuss that carbon markets in Asia are facing some challenges, which include the lack of a specialized regulator, a shortcoming that has led to inadequate monitoring, reporting, and verification mechanisms, which in turn affects the stability and credibility of the market [16]. In addition, inadequate policy implementation, particularly in introducing sufficient emission allowances and supporting market demand, has impeded achieving emission reduction targets. ...

The focus of this study is to explore how carbon markets have been effective in motivating companies to reduce carbon emissions globally. Through the setting of emission quotas and a series of fair and strict trading rules, the carbon market not only stimulates the intrinsic motivation of enterprises to reduce greenhouse gas emissions but also pushes forward climate governance on a global scale. This paper elaborates on the theoretical basis and operational mechanism of the carbon market, especially its key role in facilitating enterprises to reduce emissions through economic incentives, improving their ability to comply with environmental regulations, creating more market access opportunities, promoting innovation in environmental technologies, and enhancing the green brand image of enterprises in the eyes of the public. This study aims to provide insights for business managers to help them optimize their carbon reduction strategies and references for policymakers to promote corporate emissions reduction more efficiently and accurately when formulating relevant policies to jointly address global climate change challenges.
... In a study on environmental implications in BRICS countries (i.e., Brazil, Russia, India, China, and South Africa), the authors determined that increased globalization, as opposed to climate action, was the main driver in increasing environmental policies, such as environmental taxes and sustainable development initiatives, including environmental innovation [21]. Conversely, Shi et al. [22] reviewed the relationship between the ETS in Shanghai and Shenzhen, as well as between the ETS in the European Union and China, and found a positive relationship between the Shanghai and Shenzhen exchanges, but no significant relationship between the EU and China exchanges. ...

Carbon Pricing Instruments (CPIs), such as Carbon Taxes and Emission Trading Schemes (ETSs), have been launched in several countries, primarily in Europe and North America, as a means of limiting the emissions of greenhouse gases (GHGs) which have been known to cause climate change. The adoption of these measures in Asia has been controversial, with many arguing that they would limit economic development in the region. We review the CPIs of 18 Asian economies, 7 of which have adopted a CPI during our review period from 1990 to 2021. We perform a comparative analysis of the economies in Asia, applying the Kaya Identity to decompose the variables affecting carbon emissions and the Nearest Neighbor Matching technique to compare the effect that CPIs have on countries adopting these policies relative to other jurisdictions. We found a positive and significant effect of CPIs on reducing carbon emissions in the Asian countries compared in our study. This offers crucial insights for policymakers, stressing the effectiveness of CPIs in balancing environmental sustainability with economic development in the region.
... In this context, a collection of climatic actions by the RCEP member countries has already been under intense discussion. For example, Australia, China, New Zealand, South Korea, and Japan have established their domestic carbon emission trading system [3]; Australia and China launched a joint expert group in 2013 to explore the possibility of linking carbon trading markets [4]; some other member countries have set ambitious climate targets-China, Japan, and South Korea have successively pledged their carbon-neutrality target-and are proactively seeking multilateral climatic cooperation. Multilateral climatic cooperation is also advancing worldwide: An EU-wide emission trading system has been in effect for a decade and has been proven to be economically efficient in emission mitigation [5]. ...

Emission convergence is a fundamental ground for cooperative CO2 emission mitigation. We investigate the emission convergence in the Regional Comprehensive Economic Partnership (RCEP) countries using a modified dynamic β-convergence model. From 2000 to 2017, the per capita emissions of the RCEP countries and its subgroups show a statistically significant diverging pattern. Nonetheless, upon accounting for multiple inputs and outputs using data envelopment analysis, we find that two out of the three emission performance indicators show statistically significant absolute convergence. The carbon emission efficiency (CEE) of the 15 RCEP countries grew from 0.5719 in 2000 to 0.6725 in 2017 and will converge at a value of 0.8187, while the carbon–population performance (CPP) increases from 0.4534 to 0.5690 and will converge at 0.7831. Furthermore, using a conditional β-convergence model, we find that trade volume has no significant effect on the growth rates of CEE and CPP, but can accelerate their speed of convergence, which indicates that the establishment of the RCEP may facilitate the convergence of its 15 member countries on CEE and CPP. Our findings suggest that emission mitigation agreement in the RCEP countries is feasible. CEE- or CPP-based indicators can be used for emission budget allocation.

This paper provides a detailed analysis of the Tokyo Metropolitan Emissions Trading Scheme (Tokyo ETS), Japan’s first emissions trading scheme with mandatory cap initiated by the government of Tokyo. Unlike trading schemes in other countries, the Tokyo ETS covers indirect emissions from the commercial sector. It is well known that a variety of market barriers impede full realization of energy efficiency opportunities, especially in the commercial sector. Experiences with the Tokyo ETS should therefore provide important lessons for the design of climate change mitigation policies, especially when targeting the commercial sector. The emissions from covered entities have been drastically reduced from those at the scheme’s outset, with an average 14% reduction as of the end of the first commitment period of five years (2010–2014) compared with 2009 levels. This paper shows that the Tokyo ETS alone did not cause these reductions; there were other drivers. Among them, the energy savings triggered by the Great East Japan Earthquake in 2011 were crucial. The contribution of credit trading, in contrast, was limited since most of the covered entities reduced emissions by themselves. Through an investigation of official reports, an assessment of the emissions data from the covered entities compared to those of uncovered entities and in-depth interviews with firms covered by the scheme, this paper confirms that the main drivers of emissions reductions by covered entities were separate from the ETS. In fact, the advisory aspect of the scheme seems to be much more important in encouraging energy-saving actions. Key policy insights • Most of the observed emission reductions were not caused by the Tokyo ETS alone. • An advisory instrument was crucial to the effectiveness of the Tokyo ETS. • The experience of the Tokyo ETS suggests that making full use of the advantages of emissions trading is difficult in the case of the commercial sector. • Price signals have not provided a stimulus to climate change mitigation actions, which implies that establishing a cap to yield effective carbon prices poses a challenge.

This research paper aims to explore the role of FDI inflows and stock market development on the promotion of renewable energy consumption. Further, study investigates the effect of renewable energy consumption on CO2 emissions and economic output across a panel of Brazil, China, India and South Africa. Study utilizes annual data from 1990 to 2012 and employs various robust panel econometric techniques. The findings confirm that both FDI inflows and stock market development play an important role in promoting renewable energy consumption. The results also reveal that renewable energy consumption helps to mitigate the growth of CO2 emissions and promotes economic development.

New analysis suggests that the impacts of climate change in Southeast Asia may be larger than previously estimated, possibly reaching 11% of gross domestic product by 2100. Southeast Asia is likely to sustain larger economic losses from climate change than most other areas in the world. Moreover, those losses—the collective effect of impacts on agriculture, tourism, energy demand, labor productivity, catastrophic risks, health, and ecosystems—may be larger than previously estimated. When these loss estimates are considered simultaneously in the modeling, gross domestic product (GDP) is found to be reduced by 11% in 2100 under the business as usual emissions scenario of this study, which is 60% higher than the earlier ADB assessment. Climate change is a global concern of special relevance to Southeast Asia, a region that is both vulnerable to the effects of climate change and a rapidly increasing emitter of greenhouse gases. From 1990 to 2010, carbon dioxide (CO2) emissions in Southeast Asia have grown more rapidly than in any other region of the world.

This study contributes to the existing literature on optimal carbon mitigation policy by quantifying the impacts of various sectoral coverage options for the emissions trading systems (ETS) used to achieve China's Intended Nationally Determined Contribution (INDC) targets for the Paris Agreement on climate change. The CHEER model, a computable general equilibrium (CGE) model of China with detailed representation of electricity and other energy intensive sectors, as well asa complete CO2 emissions accounting module and carbon market, is used in this study. Results show several important findings. First, China's INDC targets can be achieved through an economy-wide ETS at an economic cost of 2.1% of real GDP by 2030. Second, including only the eight sectors proposed for initial implementation of the ETS in China is likely to result in a much larger mitigation cost than the economy-wide approach, estimated to be as high as 10.5% of 2030 real GDP. Thirdly, this study further indicates that the mitigation costs can be reduced to 3.3% of real GDP in 2030 if other energy-intensive sectors, accounting for additional 24.8% of total emissions, are included in the ETS. Asa result, not all sectors are required to get close to the first-best mitigation option so long as critical sectors are not excluded. In addition, the temporal dimension of mitigation costs and air pollution co-benefits under different sectoral schemes of China's ETS gives policy-makers a degree of short-run flexibility in terms of phasing in additional industries over time.

With the growing literature related to climate change mitigation measures and policy interventions, a systematic review of the application of computable general equilibrium (CGE) model is inevitable. Therefore, this article aims to characterise the relevant studies, define a comparative framework to identify the current state-of-the-art and the gaps in applied general equilibrium models. Firstly, the systematic review found a total of 301 research articles from Scopus and Web of Science databases and finally analysed 154 articles based on inclusion and exclusion criteria from 67 refereed journals. The review analysis found that application of CGE model is very vital in addressing climate change mitigation issues at the national, regional and global levels. However, China attracted the most substantial research interests followed by the USA, India and Australia, among others, which are in line with their share of greenhouse gas emissions in the world. Most of the research themes focus on the carbon tax, emission reduction target, emission trading, renewable energy, energy efficiency, and carbon capture and storage as primary drivers of low carbon economy. Nevertheless, there is a trend of employing more static CGE model compared to the dynamic CGE, although application of the latter has a limitation of providing right inputs to the macroeconomic policy. Finally, research directions and gaps envision other complementary models such as dynamic stochastic general equilibrium (DSGE) and agent-based model (ABM) for proper policy interventions.

There is a growing concern among both individuals and policy makers in relevance to increasing CO2 emissions across the world. As a result, international organizations have started to pressurize economies to minimize their carbon emissions by increasing the share of clean energy consumption in total energy use. Hence, the goal of this paper is to empirically explore to what extent both domestic (stock market) and foreign (FDI inflows) capital affect clean energy uses across the EU, the G20, and OECD, spanning the period 1993–2012. The results of long-run elasticities document that both FDI and stock market developments play a significant role in promoting clean energy uses across all three-country groups. The results also suggest that clean energy consumption has a considerable positive and negative effect on economic output and CO2 emissions, respectively, while the political globalization has a substantial negative impact on carbon emissions across the EU, the G20 and OECD economies.

This study investigates the impact of both FDI inflows and stock market developments on clean energy use across 20 emerging market economies, spanning the period 1991–2012. It accounts for cross-sectional dependence and heterogeneity in the analysis and employs robust panel econometric techniques. The empirical results on long-run elasticities display that economic output, FDI inflows and stock market developments have all a significant positive impact on clean energy consumption. Finally, the results on heterogeneous panel non-causality tests indicate the presence of unidirectional causality running from FDI to clean energy consumption in the short-run. For robustness purposes, the paper also estimates long-run elasticities for individual countries, with the findings documenting that both FDI inflows and stock market developments have a considerable positive impact on clean energy uses. The findings urge that both policy makers and governments in these emerging market economies should initiate effective public-private-partnership investments in clean energy projects by providing lucrative incentives, which, in turn, will encourage both domestic and foreign investors to invest more in clean energy projects and, eventually, moving these economies towards sustainable economic growth.

To fulfill its Copenhagen pledges to control carbon emissions and mitigate climate change, China plans to establish a nationwide emissions trading scheme (ETS) in 2016. This paper develops a multi-sector dynamic computable general equilibrium model with an ETS module to study the appropriate ETS policy design, including a carbon cap, permit allocation and supplementary policies (e.g., penalty policies and subsidy policies). The main results are as follows. (1) To achieve China's Copenhagen pledge, the equilibrium nationwide carbon price is observed to be between 36 and 40 RMB yuan per metric ton. (2) The ETS policy has a cost-effective mitigation effect by improving China's production and energy structures with relatively little economic harm. (3) Various ETS sub-policies should be carefully designed to balance economic growth and carbon mitigation. In particular, the carbon cap should be set according to China's Copenhagen pledge. A relatively large distribution ratio of free permits, the output-based grandfathering rule for free permits, a penalty price (on illegitimate emissions) slightly above the carbon price, and a sufficient subsidy (from ETS revenue) are strongly recommended in the early stages to avoid significant economic loss. These designs can be adjusted in later stages to enhance the mitigation effect.
