Debates on carbon costs and carbon pricing to accelerate the reduction of greenhouse gas (GHG) emissions are emerging as cities develop local policies and programs to achieve carbon neutrality. This paper focuses on how cities formulate economic instruments and adopt carbon pricing experiments to support their climate objectives. Extensive literatu...

Air pollution and climate change are closely interlinked, once both share common emission sources, which mainly arise from fuel combustion and industrial processes. Climate mitigation actions bring co-benefits on air quality and human health. However, specific solutions can provide negative trade-offs for one side. The Portuguese Carbon Neutrality...

The energy sector has a vital role in climate change mitigation. In Brazil, the electricity generation sector is strongly dependent on hydropower generation, but thermoelectricity contribution has increased leading to a more carbon-intensive electricity mix. This trend will be aggravated with the expected significant increase in the electricity dem...

Urban areas constitute over three-fourths of the current global economy, house more than half of the global population and consume more than two thirds of final global energy consumption with the consequential greenhouse gas emissions. New dynamics are occurring with cities becoming vectors of sustainable development, through initiatives like the C...

Smart city (SC) has emerged during the last 2 decades to a broad scientific domain and a dominant industrial market, which attract an interdisciplinary attention. All the scientific fields -from the information and communications technologies (ICT) to the economics and environmental studies or even the humanities- and all the industries -from the I...

In a world where an increasing share of the population lives in cities, its energy transition is gaining more relevance. The decision-making process in urban planning is frequently fragmented across departments considering different criteria. Integrated city planning approaches are not commonly employed, especially for the promotion of sustainable...

During the last decade, professional analytical tools and platforms are increasingly more used to analyse and support decision-making regarding urban energy systems. Most of existing urban energy platforms are focused on short-term analysis (present or 2020) and cover specific sectors and/or aspects, without considering the holistic optimisation of...

The recent decrease in solar photovoltaic (PV) investment cost has transformed the attractiveness of the technology. Southern Europe has one of the highest levels of solar radiation in the world, and policy makers are very keen to take full advantage of this resource for electricity and heat production. However, physiographic characteristics and sp...

Energy use in cities has attracted significant research in recent years and city level energy planning is becoming a required task driven by the contribution of decentralized renewable electricity production and a demand-side approach towards greenhouse gases emissions reduction. However, traditional energy planning approaches are limited because t...

Urban areas have a pivotal role to play in climate change mitigation, as they are responsible for a high share of energy consumption and provide many opportunities for more efficient supply & use of energy. This makes the case for energy system modelling at city level, as done within the INSMART EU project, which identified the optimum mix of measu...

In order to achieve the goal of the Paris Agreement on Climate Change to limit average global temperature rise to well under 2 °C, concerted action will be needed in cities to manage energy consumption and reduce greenhouse gas emissions. But, what can be done at city level to move towards such a global ambitious target? The project InSMART (Integr...

Natural gas plays an important role in the Southern cone energy system, and is expected to increase in primary supply in the future. This paper presents a new energy systems model for the Southern Cone region of Latin America, covering five regions (Argentina, Bolivia, South and Centre Chile, North Chile, and Brazil) with the aim to explore, up to...

Findings and lessons learnt for European cities from the INSMART project: A new methodology for smarter energy planning, tested in four EU cities. An EU-funded project under the FP7 Programme with 10 partners from 4 member states 2013-2017

Presentation describing the overal methodology and selected results for the Évora case study within the EU INSMART project.

Energy system models as TIMES or PRIMES support policy makers in energy and climate change mitigation policies, as the EU-wide energy efficiency (EE) goal of 30% by 2030. Model outputs are determined by assumptions, some of which are tested. However, the economic development assumptions considered in the models are less experimented with. Economic...

Electric vehicles (EVs) are considered alternatives to internal combustion engines due to their energy efficiency and contribution to CO2 mitigation. The adoption of EVs depends on consumer preferences, including cost, social status and driving habits, although it is agreed that current and expected costs play a major role. We use a partial equilib...

This paper estimates the amounts of critical metals required for the deployment of the 2050 Low Carbon Roadmap for Portugal and assesses how including concerns with their availability within the TIMES_PT energy system model affects the profile of low-carbon electricity technologies for 2050. We conclude that long-term availability of dysprosium, ne...

A key objective of IEA-ETSAP is to assist decision makers in robustly developing, implementing and assessing the impact of energy and climate mitigation policies. This chapter focuses on four case studies, in which there is clear evidence of a direct link between the use of MARKAL and TIMES scenario modelling activities and the resulting policy dec...

The first publically available energy projections for Portugal date from 1982 for the period 1990-2010 as part of the first National Energy Plan. They were reviewed in 1984 and 1993 considering updated macro-economic projections and energy efficiency measures, respectively. In 1995 three scenarios were made for 1995-2015 and the first 2020 energy p...

The increase of renewables in power sector, together with the increase of their electricity share in final energy consumption, is changing our perception about energy security with diverse and contradictory statements. The Portuguese security of electricity supply is analyzed in this study by comparing selected indicators for 2 years before and aft...

The complexity of energy systems operation and the necessity to design secure and reliable systems, compatible with greenhouse gas (GHG) mitigation goals, have justified the development of energy models. They are capable of representing detailed energy systems (technical and economic characteristics) and the interconnections between supply and cons...
