SAF policy scorecard: Evaluating state-level sustainable aviation fuel policies in the United States
This paper compares key provisions in current and planned state SAF policies and assesses their strengths and weaknesses.
The impact of the proposed “first productive use” requirement for biogas for Inflation Reduction Act 45V tax credits
This brief highlights the importance of the “first productive use requirement” in the proposed guidance for the Section 45V tax credits.
Evaluating the policy value of dairy biomethane-derived hydrogen in California’s Low Carbon Fuel Standard
This brief provides key takeaways and recommendations for policies to limit the contribution of out-of-state, out-of-sector Low Carbon Fuel Standard credits.
A comparison of the life-cycle greenhouse gas emissions from combustion and electric heavy-duty vehicles in India
Evaluates the greenhouse gas impacts of different heavy-duty vehicle technologies in India, showing that battery-electric vehicles offer the greatest emissions reductions, enhanced by renewable energy, whereas the benefits of fuel cell vehicles vary based on the hydrogen source.
Feasibility study of future energy options for Great Lakes shipping
Evaluates future energy options for Great Lakes shipping, analyzing alternative fuels and technologies against environmental regulations, costs, and emissions, aiming to guide the industry towards decarbonization by 2050.
Evaluating the potential role of a National Low-Carbon Fuel Standard to support sustainable aviation fuels
Investigates the integration of aviation fuels into a national low-carbon fuel standard (LCFS) policy, highlighting the potential for LCFS policies to promote sustainable aviation fuels (SAFs) and reduce greenhouse gas emissions, with policy design choices playing a crucial role in shaping their effectiveness.
Meeting the SAF Grand Challenge: Current and future measures to increase U.S. sustainable aviation fuel production capacity
Assesses the feasibility of meeting the administration’s SAF Grand Challenge based on resource availability, production costs, technology readiness level, and policy support.
Assessing the risks of crediting alternative fuels in Europe’s CO2 standards for trucks and buses
Assesses proposed mechanisms to credit alternative fuels in Europe’s CO2 standards for trucks and buses and identifies potential climate risks that would dilute the emission reduction benefits of the European Commission’s proposal.
Risks of crediting alternative fuels in Europe’s CO2 standards for trucks and buses
This fact sheet assesses proposed mechanisms to credit alternative fuels in Europe’s CO2 standards for trucks and buses and identifies potential climate risks that would dilute the emission reduction benefits of the European Commission’s proposal.
Drawbacks of adopting a “similar” LCA methodology for U.S. sustainable aviation fuel (SAF)
Highlights key differences in the life-cycle assessment (LCA) methodologies used to estimate the greenhouse gas emissions from sustainable aviation fuel.
