Sustainable Aviation Fuels / Addressing Local Air Quality Context: U.S. Airlines’ Have a Strong Environmental Record ➢ Strong climate change commitments since 2009 – strengthened significantly in 2021 (see next slide) ➢ Strong supporters of standards for aircraft and engine emissions standards, including Aircraft CO2 and noise standards, Oxides of Nitrogen (NOx ) and particulate matter (PM) engine emissions standards ➢ Strong supporters of Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) ➢ Improved fuel efficiency over 135% from 1978-2021 ➢ Help drive ~5 percent of U.S. GDP while accounting for just ~2 percent of U.S. GHG emissions ➢ 94% reduction in significant noise exposures 1975-2019 (passengers up 379%) ➢ CO and smoke virtually eliminated; NOx from aircraft continually reduced Pathways to Improve Upon That Record ➢ Technology: New aircraft/engines plus enhancements (e.g., winglets) and R&D for breakthroughs ➢ Operations: Weight reduction, cargo distribution, engine wash, single-engine taxi, ground power at gates ➢ Infrastructure: Delivering 21st Century air traffic control (“NextGen”) ➢ Sustainable Aviation Fuels (SAF) – liquids for now, but electric/hybrid or even hydrogen in long term U.S. Airlines Led in Making Very Ambitious Climate Change Commitments March 20, 2021: “A4A and our member airlines commit to working with government leaders and other stakeholders in a positive partnership to achieve the following stepwise goals” • Long-Term: Reduce net carbon emissions to zero by 2050 (2050 NZC) • Medium-Term: Make 2 billion gallons of cost competitive SAF available to U.S. operators in 2030 • Near-Term: Reaffirm goal to limit…
