Decarbonizing transport remains one of Europe’s greatest challenges, with aviation, shipping, and heavy industry among the hardest sectors to abate. Sustainable Aviation Fuel (SAF), Sustainable Maritime Fuel (SMF), and biomethane present viable pathways to reducing emissions while leveraging existing infrastructure for a faster transition. This white paper provides a strategic analysis of Europe’s sustainable fuels landscape, exploring market dynamics, regulatory developments, and breakthrough projects. It delivers actionable insights into policy, technology, and investment trends, offering a roadmap for stakeholders navigating the shift toward low-carbon fuels and supporting Europe’s long-term climate and energy transition objectives.
