  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.
