The Renewable Energy Directive III (REDIII) aims to drive the adoption of renewable energy sources by creating a favorable regulatory framework, particularly emphasizing the use of renewable fuels of non-biological origin (RFNBO) in transport and industry. The directive sets ambitious targets, including doubling renewable energy targets in the transport sector compared to REDII. However, the implementation of REDIII faces challenges, with many EU Member States struggling to transpose the directive into national law by the deadline of May 21, 2025. Delays are primarily linked to complexities in meeting RFNBO targets, choosing compliance methods, and aligning with other relevant EU legislation. To address these challenges, an expert panel comprising representatives from European institutions, national authorities, and affected companies will convene to discuss best practices and potential pitfalls in implementing REDIII. The session will cover topics such as compliance mechanisms, national target setting, penalties for non-compliance, and harmonization with other renewable fuel regulations. Notable speakers include experts in renewable energy, hydrogen, and energy policy, offering valuable insights on designing effective national strategies to meet REDIII objectives in a sustainable manner.
