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 ...
Dossier: Climate-damaging subsidies correspond to negative CO2 prices
The aim of this dossier is to convert the significant level of subsidies in the transport sector into negative CO2 prices; this contributes to the political discourse by categorising the climate policy significance of the subsidies. The implicit negative ...
Brief: Making price signals comparable – subsidies as negative CO2 prices
Calculations in a new Ariadne study show that subsidies in the transport sector sometimes correspond to negative CO2 prices of between -€70 and -€690 per tonne of CO2. Germany’s current tax and levy system in the transport sector is ...
