Sustainability of the forest biomass energy: lessons learned from the CJEU’s Robin Wood judgment

Vivien Köböl-Benda

The European Union expressed its commitment to meet the Paris Agreement’s temperature goal – holding the increase in the global average temperature well below 2°C above pre-industrial levels while pursuing efforts to limit the temperature increase to 1.5°C – in several acts. The EU committed itself to achieving net climate neutrality by 2050 and introduced various legal and policy instruments serving this goal, such as the framework for sustainable finance with the Taxonomy Regulation. This instrument’s objective is to combat greenwashing by establishing the criteria for assessing an economic activity’s sustainability. In practice, the Commission’s delegated acts can elaborate on its technical background by defining screening criteria. In 2026, the Court of Justice of the European Union (CJEU) rejected the arguments of several NGOs, contesting the Commission’s technical screening criteria on the use of forest bioenergy. The applicants claimed that more stringent and forward-looking criteria are necessary regarding the sustainability of forest biomass to meet the Paris Agreement’s goals and realize effective mitigation. Even though several studies pointed out the declining state of the EU’s carbon sinks and confirmed that the use of forest bioenergy may, in certain cases, have harmful effects, the CJEU left a broad margin of appreciation to the Commission and rejected the applicant’s arguments. The judgment considered the technical aspects of the Taxonomy Regulation, but also addressed issues relating to NGO enforcement, the required standard of proof, and the possible direct effect of the UNFCCC and the Paris Agreement goals.
