Despite years of sustained interest in sustainable aviation fuels (SAFs), the industry has been slow to expand in the face of strong economic barriers to deployment.

The European Union (EU) is considering ambitious alternative fuel policies to decarbonize aviation. However, it is critical that policymakers set realistic sustainable aviation fuel (SAF) deployment goals that match the amount of fuel that could be made from available feedstock.

This working paper provides background and analysis to help identify how an effective policy for alternative aviation fuels could distinguish among fuels that can deliver deep greenhouse (GHG) reductions and those that cannot.

Low-carbon fuel standards (LCFS), which regulate the carbon intensity of fuels supplied to transportation, can provide long-term, durable funding for EV infrastructure and EV purchasing incentives as other policies such as rebates expire or are phased-down.

While public awareness of indirect land-use change emissions from using food commodities for biofuels has grown over recent years, the indirect climate impacts of advanced biofuels made from by-products, wastes, and residues are less well understood.

India’s 2018 National Policy on Biofuels sets ambitious biofuel targets of 20% ethanol blending and 5% biodiesel blending, both by 2030, and aims to source these biofuels only from sustainable feedstocks that do not threaten food security.

This working paper examines the kinds of near-term incentives and supporting actions that are necessary to make battery electric vehicles (BEVs) a viable purchase option for drivers in Indian ride-hailing fleets.

This working paper assesses the potential for Germany to meet the transport sector targets set by the European Union's recast Renewable Energy Directive (RED II) using advanced, non-food-based fuels.

Brazil’s advanced biofuel industry lags far behind the production capacity of its first-generation biofuel industry.

Significant greenhouse gas savings are possible by transitioning from first-generation, food-based biofuels to advanced alternative, non-food based fuels.
