Supply and sustainability of carbon offsets and alternative fuels for international aviation
The report evaluates the feasibility of ICAO's 'carbon neutral' goal for international aviation growth from 2020 onward. It finds that a selective approach to carbon offsets—focusing on high-integrity projects like methane avoidance—could meet 70–90% of projected demand (3.3–4.5 Gt CO2e) between 2020 and 2035. Including medium-confidence projects would further increase supply to 5.1 Gt CO2e, with REDD+ potentially adding 2.4 Gt CO2e. Alternative biofuels offer lower cumulative reductions (0.1–0.3 Gt CO2e) and face significant challenges regarding land use change and sustainable development, particularly with oilseed crops.
