The generation of electricity and heat is the largest single activity covered by the EU Emissions Trading System (EU ETS). Due to the interconnectedness, the difference in the emission intensity of the different fuels and their configuration in a competitive marginal cost pricing market, power...

Iron and steelmaking is the industrial sector with the highest absolute CO2 emissions covered by the European Union Emissions Trading System (EU ETS). This report aims to describe key developments of the sector in the period from 2005 to 2019. It identifies key drivers behind the trends in...

The effectiveness of an emissions trading system in terms of reducing greenhouse gas emissions is mainly due to the magnitude of the specified emission cap. Assuming sufficient control, a quantitative emission target defined in such a way is quasi automatically achieved by the limited allocation...

This report analyses the influence of the Cap and Trade (CaT) system and the electricity market in California along two main questions: How do CaT design features affect the environmental effectiveness of the system and the quality of the carbon price signal? How do electricity market design...

This report analyses the interaction of the European Emissions Trading System (EU ETS)and the German and Polish electricity markets along two main questions: How do EU ETS design features affect the environmental effectiveness of the system and the quality of the carbon price signal? How do...

In addition to carbon dioxide, air traffic operation affects the climate through other emissions and atmospheric processes, such as the formation of ozone and contrail cirrus. The climate impact of these non-CO2 effects is strongly dependent on the emission location (in particular cruise...

This report assesses options for the effective implementation of sustainable development impact assessment, in the context of climate change mitigation mechanisms such as those of Article 6 of the Paris Agreement. Existing carbon crediting programmes were analysed to draw insights on the best...

Air transport is a sector with particularly dynamic emissions growth. The European Union has led the way in climate protection and included aviation in the European Emissions Trading Scheme (EU ETS) in 2012. To support the international process for a global market-based measure to limit...
