In the European Union (EU), a second emissions trading system (EU ETS2) covering buildings, road transport and small energy and industrial installations is expected to be introduced from 2027. Until 2030, however, EU ETS2 will not be a separate pillar of EU climate policy, but will support...

With the Green Deal, the European Union (EU) has not only significantly increased the ambition of its climate policy in recent years, but it has also added an international dimension to European domestic climate policy. In fact, numerous recently adopted legal acts directly or indirectly affect...

The role of permanent carbon dioxide removal (CDR) from the atmosphere is currently the subject of intensive discussion within the context of developing a new EU emis­sions reduction target for 2040 and a German long-term strategy on negative emissions. At the same time, a short-term strategy...

The outgoing European Commission has published its Communication on a 2040 climate target as its last major climate policy initiative before the 2024 European elections. By recommending a net emissions reduction target of 90 per cent compared to 1990 levels, it lays the strategic foundations for...

Climate policy in the European Union (EU) and Germany changed significantly with the adoption of net-zero emissions targets. A key new development is the growing importance of carbon management. The umbrella term includes not only the capture and storage of CO2 (carbon capture and storage, CCS),...

Under the European Union Emissions Trading System (EU ETS), operators must surrender allowances corresponding to the emissions of greenhouse gases (GHG) from their installations. The supply of allowances in the EU ETS decreases linearly and, all else equal, is expected to end around 2057. An...

In 2005, the European Emission Trading Scheme (EU-ETS) established a new commodity: the right to emit a ton of CO2 (EUA). Since its launch, the corresponding price has shown rather turbulent dynamics, including nervous reactions to policy announcements and a price collapse after a visible...

Diminishing emission budgets and increasing risks of catastrophic damages from climate change require analyses of rapid response options including geoengineering options such as ocean iron fertilization (OIF). To decide whether or not OIF might be such an option an assessment of its potential as...

To stay within the 2°C temperature increase target for climate change calls for ambitious emission reduction targets already for the 2012-2020 compliance period. Cost-efficiency is a crucial criterion for the enforcement of such ambitious targets, requiring analyses of all possible abatement...
