ICAO technical body issues major analysis on feasibility of a global aviation emissions reduction goal

Annual residual CO2 emissions from international aviation – those emissions that remain after in-sector reduction efforts – could range from 200 million tonnes (Mt) to 900 Mt by 2050, according to a major study by ICAO’s Committee on Aviation Environmental Protection (CAEP). The completed report provides the results of two years of technical work by 280 experts from around the world to explore the feasibility of a long-term global aspirational goal (LTAG) for international civil aviation CO2 emission reductions. Described as the most comprehensive and complex study of its kind, the analysis provides long-term trends and emissions reduction opportunities from operations, new aircraft technologies and future fuels and energy sources against a backdrop of traffic demand forecast scenarios and the climate science. The results show a heavy reliance on sustainable fuels for the most optimistic outcome on in-sector reductions. A decision on whether to adopt a long-term emissions reduction goal is expected to be taken at ICAO’s next triennial Assembly that starts in late September.
