The German Association for Negative Emissions (DVNE) has urged the German government to improve the conditions for voluntary carbon markets in the agriculture and forestry sector. It argues that the markets could help turn the sector back into a carbon sink instead of a carbon source. The restructuring of German beech and spruce forests alone would require investments of between 14 and 43 billion euros over the next 30 years, the DVNE stated in a study that will be presented this Thursday and was made available to Table.Briefings in advance. This would hardly be achievable through public investment. Carbon markets are an instrument to close the financing gap, DVNE said.
