The aviation sector contributes 2% of global CO2 emissions, with projections suggesting these could triple by 2050 without policy intervention. While Sustainable Aviation Fuels (SAFs) are the primary current solution, the report argues that the term is imprecise and that relying solely on biofuels would require quadrupling global production by 2030 and quintupling it by 2040, posing severe risks to land use, biodiversity, and food security. To meet projected global energy demands of 15.9 quads in 2030 and 21.5 quads in 2050, the report advocates for a shift toward scalable zero-emission fuels (SZEFs)—including hydrogen and synthetic fuels created via direct air capture (DAC)—and electric propulsion. It provides specific policy recommendations for the U.S. and EU, including RD&D investments, carbon intensity standards, and the phasing out of free emission allowances.

The document argues that the rapid growth of generative AI is driving a significant increase in electricity demand, which threatens climate goals by incentivising the continued use of fossil fuels and diverting clean energy resources. It highlights a lack of transparency in corporate emissions reporting, where 'market-based' accounting masks actual grid impacts, and warns that 'moonshot' technology promises like nuclear fusion may act as mitigation deterrence. Specific examples include data centre growth in Ireland and Malaysia, and the rising emissions profiles of companies like Microsoft and Google.
