Report: A cost-efficient energy transition: Scenarios for climate neutrality 2045 – Summary
Summary Climate change is not slowing down. In 2024, two significant records were set: for the first time, the global mean temperature exceeded +1.5 °C above pre-industrial levels (Copernicus Climate Change Service, 2024), and global CO2 emissions reached a new …
Background: Staying the course in turbulent times – Insights on the current state and ways forward for the EU’s climate, energy and finance policy architecture
With the Fit for 55-package, the EU increased the ambition level of its energy and climate targets for 2030. The targets reflect the EU’s commitment towards an energy system transformation – or, in fact, the transformation of the entire …
Ariadne-Analysis: Hydrogen in the Reformed EU ETS – Implications for Competitiveness and Emissions Reductions
The use of renewable hydrogen is considered an important element for the decarbonization of sectors that are hard to electrify, such as the steel and chemical industry or aviation (European Commission 2020, Ferrario et al. 2022). However, the volume …
Analysis: Selling CBAM – Diplomacy for the European Union’s Carbon Border Adjustment Mechanism
The analysis addresses the question of how the EU’s key institutions understood their diplomatic role with regard to the Carbon Border Adjustment Mechanism. Which EU institutions communicated with third coun-tries? What channels did they use? Who was taking the …
Analysis: Low carbon hydrogen in the European Union – A coherent regulatory framework
Renewable hydrogen is necessary for the decarbonization of sectors that are difficult to electrify, such as industry and aviation, and as a storage medium for surplus electricity from renewable sources. In this context, the following analysis of the EU …
