The EU’s Renewable Energy Directive III (RED III) is set to reshape Europe’s energy landscape, and the maritime sector is at the heart of this transition. As regulations evolve, understanding what RED III requires and how it is being implemented across Member States is increasingly important for organisations working toward decarbonisation.

RED III raises the EU’s overall renewable energy ambition, mandating that by 2030, 42.5% of all energy consumed must come from renewable sources. Within the transport sector, at least 14.5% of energy use must derive from renewable fuels, with growing emphasis on those considered most sustainable.

A major component of the directive is its focus on advanced biofuels: fuels produced from waste and residue materials listed in Annex IX Part A, such as manure, sewage sludge, and agricultural residues. A smaller category, Annex IX Part B, covers feedstocks like used cooking oil and certain animal fats, though the use of these varies by country. Beyond biofuels, RED III aims to accelerate the adoption of renewable fuels of non‑biological origin (RFNBOs), including green hydrogen and synthetic e‑fuels produced with renewable electricity. These fuels are expected to become essential for hard‑to‑electrify sectors, especially maritime transport.

Compliance mechanisms are also evolving. Some EU countries have begun using a fuel “ticket” or certification system to monitor renewable fuel usage. Under this approach, each supply of renewable fuel generates a tradable certificate (a ticket), enabling suppliers to demonstrate compliance with national targets. As of January 2026, the Netherlands is the only country formally operating such a system, though wider adoption is anticipated as RED III continues to be integrated across the EU.

Implementation progress differs significantly between Member States. Denmark and the Netherlands have already incorporated RED III requirements into national law, positioning themselves as early leaders. Finland and Sweden are moving steadily toward full compliance. In Germany, RED III transposition is underway, though marine fuel providers are not yet subject to the associated obligations. Meanwhile, Spain is developing its national framework, with Peninsula actively contributing to the consultation process to support clarity and practical alignment for the maritime sector.

To help demystify some of the misconceptions surrounding the directive, we spoke with Miguel Gutierrez, Decarbonisation Analyst at Peninsula. He emphasised the importance of transparent certification and validation:

“There is a lot of misinformation about RED III and the certification process. It’s important to make sure that any certification is traceable and trusted, validation is key. We also need our clients to be aware that Peninsula is completely compliant with RED III, but if any of our clients have any questions about the directive, reach out to our team!”

RED III marks a decisive step forward in Europe’s renewable energy ambitions. As the maritime sector adapts to a more regulated and sustainability‑driven future, understanding the directive, and the evolving landscape around it, is critical. Peninsula will continue to support customers in navigating these changes with informed, certified, and compliant solutions.
