Fuel burn of new commercial jet aircraft: 1960 to 2024
Stricter fuel efficiency standards and policies are needed to drive further reductions in aircraft fuel burn, especially for new aircraft types and freighters, to align with aviation’s net-zero emissions goal.
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.
Vertical Take-off? Cost Implications and Industrial Development Scenarios for the UK SAF Mandate
Examines the cost implications of the proposed SAF mandate targets from an industrial development perspective.
Lifetime emissions from aircraft under a net-zero carbon budget
To meet the international goal of net-zero carbon dioxide emissions by 2050, all new aircraft delivered after about 2035 will need to emit zero net CO2 emissions throughout their operational lifetimes.
Demand response to aviation carbon pricing in Canada
Models the effect of introducing a Canada-wide carbon price on interprovincial flights and assesses a scenario of using a frequent flyer levy to achieve the same change in demand as carbon pricing.
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.
Regulating international aviation emissions without market distortion
Models the market impacts of regional carbon taxes on airfares via two regulatory approaches, accounting by country of operator registration and accounting by country of departure.
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.
Priorities for government spending on net-zero aviation
This study delves into the necessity of government fiscal support for decarbonizing international aviation, estimating that approximately $0.8–1.4 trillion of public investment is required to bring emerging clean aviation technologies to maturity and achieve a net-zero goal by 2050.
Towards Net-Zero Aviation State Action Plans
This briefing assesses the clarity of 17 differentiated state action plans submitted by countries around the world to meet the International Civil Aviation Organization’s goal of achieving net-zero aviation emissions by 2050.
