This report examines the potential of sustainable aviation fuels (SAFs) in reducing the environmental impact of aviation. It highlights various types of SAFs, their scalability, and the critical role of investors in supporting high-integrity fuels to achieve net-zero emissions in the aviation sector.

The policy summary discusses the US sustainable aviation fuel (SAF) policy, highlighting the favourable regulatory landscape, the Biden administration's support through tax credits and subsidies, and the SAF Grand Challenge. It also covers the different acts, state-level initiatives, and various financial mechanisms to bolster SAF production and adoption, comparing it with EU and UK policies.

The EU is developing a policy framework for sustainable aviation fuels (SAFs) to achieve net zero aviation. The ReFuelEU Aviation Initiative mandates SAF blending, with targets rising to 70% by 2050. Supporting measures include the Net Zero Industry Act and the EU Emissions Trading Scheme. Significant investment is required for this transition.

This report examines the role of e-fuels in decarbonising transport, focusing on their potential for aviation and shipping. It provides a techno-economic assessment of e-fuel technologies, evaluates necessary cost reductions and infrastructure investments, and highlights policy considerations. E-fuels, derived from electrolytic hydrogen, could diversify decarbonisation options and complement existing biofuels, especially in sectors less amenable to electrification.
