  Feasibility of sufficiency policy instruments. An assessment using impact chains for the German mobility sector

  January 2025

  The transport sector is not on track to meet the Paris Agreement climate targets. Rapid decarbonization of transport requires fuel switching and energy savings through modal shift and demand reduction – which are the aims of transport-sufficiency policy. We analyze passenger transport-policy instr

  EU 2040 Climate Target: Contributions of the Energy Supply Sector

  November 2024

  The European Union (EU) is legally obliged to achieve climate neutrality by 2050 and has an interim target for 2030 of reducing net Greenhouse Gas (GHG) emissions by 55% compared to 1990. The European Climate Law also requires the EU to adopt a climate target for 2040. In its Communication of 6 F

  Using impact chains for a feasibility assessment of sufficiency policies in the mobility sector

  June 2024

  Energy savings through modal shift and demand reduction (avoid) are key to decarbonising the transport sector. This is the aim of transport sufficiency policies. Some of them are already implemented and serve as best practice examples, and there are many planned and proposed policies, e.g., in the N

  Better soil management: Which funding approaches have a positive effect on climate mitigation?

  News 01/08/2025

  Soils play an important role as (potential) carbon reservoirs for climate mitigation. They also play a key role in promoting biodiversity and resilience to pressures such as global warming or pollution. Worldwide, soils store two to three times more carbon than the atmosphere. They act as natural climate protectors and are therefore also a key component of the EU's agricultural policy towards a net-zero future – provided they are intact. Only then can they reduce greenhouse gas emissions and/or sequester carbon.
