Abstract:This study provides the European Parliament’s Committee on Transport and Tourism (TRAN) with an assessment of the potential of sustainable fuels to decarbonise the transport sector, and help the sector achieve the 2050 decarbonisation goals. It assesses their potential for use in maritime, aviation and road transport, considering their technology readiness, feedstock availability, sustainability of supply, resource and energy efficiency, and the most appropriate match-making between fuels and applications.
