ICAO CAEP’s conclusion on the LTAG for international aviation

22 February 2022: ICAO’s Committee on Avaition Environmental Protection (CAEP) concluded its meeting on the long-term aspirational goal (LTAG) for international aviation and reached conclusions on the LTAG, new global standards and guidance and technical aspects of SAF on 18 February.

On LTAG:

• The CAEP report forsees the largest overall CO2 reductions by 2050 coming from from fuels and clean energy sources, with decreases in greenhouse gas emissions of up to 55 per cent projected. New technology, including advanced traditional and new unconventional airframe configurations were also expected to contribute to efficiency of up to 21 per cent, as well as improvements in flight performance of up to 11 per cent through innovations such as formation flying.
• Goal options will be considered in July at the LTAG High level Meeting and at the ICAO 41^ST Assembly in September-October.

On SAF:

• The CAEP agreed on amendments to life-cycle emissions reduction values, in addition to a sustainability certification framework.
• It also agreed on the LCAF methodology as a basis for calculating life-cycle emissions reduction values, while also approving the guidance for LCAF sustainability criteria.
