The energy transition requires widespread electrification of the transport sector. To promote the penetration of electric vehicles (EVs), it is essential to understand consumers’ perceptions and behavior, particularly regarding the main determinants of EV purchase and the acceptance of electric mobility (EM). With this aim, we focused on an industr...

The Textile and Clothing Industry plays a key role in the world’s economy. Over the last decades, increasing consumption and the emergence of ‘Fast Fashion’ made this sector one of the most harmful to the environment. The effects are felt over the entire life cycle of garments. This article focuses on the possible contribution of second-hand sales...

Electricity markets have been liberalized worldwide, but the success of country specific experiences varied widely. Consumers' behavior is among the key factors for successful liberalization experiences namely regarding the decision to switch operator. This decision has been shown to be influenced by a multiplicity of factors. The goal of this arti...

In this paper we analyze the role of governance quality on environmental policy in Brazil regarding natural resources exploration, particularly oil. Governance quality is reflected in five indicators following the approach of the World Bank: political stability, regulatory quality, government effectiveness, rule of law, and control of corruption. W...

We question the fiscal advantage enjoyed by diesel fuel in Portugal based on economic and environmental grounds. To do so, we estimate price and income elasticities for diesel and gasoline. Our results show that diesel consumption is inelastic to price changes in Portugal, and instead, this consumption is highly dependent on economic growth, given...

Urban parks have been increasingly important for people living in urban areas. There has been a growing need to be in contact with nature and to have a safe space to exercise and do recreational activities with family. These parks have proven to have positive health effects both physical and mentally. Furthermore, they contribute to better air qual...

Energy generation has had several negative health impacts over the last few decades, mainly due to air pollution. One of the ways to decrease such impacts is to increase energy generation through renewable energy sources (RESs). These sources have important health co-benefits that need to be taken into consideration. This topic has been included in...

Taxes often face public opposition, which hinders their implementation since people envision them as costs without a return. Taxes on emissions are one of the most common instruments to tackle environmental problems. If their revenues are used to subsidize renewables, and a double dividend is achieved, public opposition may decrease. Focusing solel...

Despite the increase in electric mobility, fossil fuels still dominate the transport sector. For a sustainable management of these fuels, environmental policy plays a significant role. It is key to know if higher taxes are effective to moderate demand, which will depend on demand elasticities. While price elasticities determine the effectiveness of...

The relationship between the economy and the environment is not straightforward and is influenced by a multitude of factors. Ideally, economic growth would not damage environmental quality and environmental protection would not hinder economic growth. Achieving this decoupling often requires environmental policy, but the analysis of specific policy...

We study the relationship between average temperatures and electricity consumption in Portugal. Control variables include electricity prices and the economic activity. Our results indicate that there is U-shaped relationship between temperature and electricity consumption. While changes in average temperature do not affect electricity consumption b...

The issue of municipal waste is regarded as one of the biggest environmental problems worldwide given its uncontrolled growth. Efficient waste management is an important step towards an energy and material sustainable society. This problem is particularly serious in insular regions due to logistic difficulties. As a result, municipalities need to f...

The need to decarbonize economic production processes is undeniable and has been considered by most countries worldwide. Renewable Energy Sources (RES) and Carbon Capture and Sequestration (CCS) technologies appear among the most promising routes to the decarbonization process. We propose an equilibrium model where final-goods production uses labor...

We propose an equilibrium model where final-goods production uses labor and energy, and energy production uses non-polluting Renewable Energy Sources (RES) and polluting fossil fuels. Our goal is to compare two alternative Green Tax Reforms (GTRs). In one of the GTRs, carbon tax revenues are used to support Carbon Capture and Sequestration (CCS) ac...

We study the difference between urban and rural elasticities for electricity residential consumption in Portugal. Our sample covers the period from 1989 to 2010 and consists of five independent surveys. We adopt the pseudo-panel methodology creating 350 cohorts based on the size of the household, the type of location (rural or urban), the region, a...

We compare the economic and environmental effects of several specifications of a green tax reform (GTR) where tax revenues are used to support renewable energy sources (RESs) and carbon capture and sequestration (CCS) activities. With this aim, we propose an equilibrium model where final-goods production uses labour and energy, and energy productio...

In this paper we study the behavior of electricity use in Portuguese households using microdata from five independent surveys. Our sample covers the period from 1989 to 2010, which was characterized by major changes in the country. We adopt the pseudo-panel methodology creating 350 cohorts based on the size of the household, the type of location (r...

We examine the relationship between the economy and the environment in a model where production uses nonpolluting renewable and polluting nonrenewable resources. There is policy intervention through a tax on emissions and a subsidy to renewables extraction/production. Results show that both instruments are able to decrease emissions intensity of ou...

We build a general equilibrium model with renewable (non-polluting) and non-renewable (polluting) resources to analyze the interaction and compatibility between economic growth and a cleaner environment. The study is in two phases: (i) resource extraction/production costs are constant; (ii) resource producers invest in knowledge to reduce extractio...

This paper develops an endogenous growth model to study the decentralized equilibrium and the optimum conditions in an economy which uses polluting resources. The model includes two policy instruments, a subsidy to final consumption and an emissions tax. It also considers two forms of endogenous technical change, pollution-reducing knowledge and ho...

Over the last years renewable energy sources (RES) have increased their share on electricity generation of most developed economies due to environmental and security of supply concerns. The aim of this paper was to analyze how an increasing share of RES on electricity generation (RES-E) affects Gross Domestic Product (GDP) and carbon dioxide (CO2)...

This article analyses the contribution of E3 models to fully understand the complex relationship between the environment, economics and the energy sector. We present a survey of the literature on these models, analyzing the assumptions, features and scope of the main kinds of methodological approaches: bottom-up, top-down and hybrid models. Since t...
