Aviation’s Climate Action Takes Off

Collaborative climate action across the air transport sector


The Aviation’s Climate Action Takes Off initiative aims to control international aviation CO2 emissions through a basket of aviation CO2-reduction measures, including a goal of carbon-neutral growth through a global market-based mechanism.


The initiative commits to support short-, medium- and long-term goals to cut emissions from aviation. It showcases action by industry and states in addressing CO2 emissions from international aviation. Measures include supporting developing new, more efficient aircraft technology and sustainable aviation fuels while promoting and deploying operational improvements to reduce CO2 emissions from aircraft already in service. It calls for better use of infrastructure, especially in air traffic management.

Through the Air Transport Action Group (ATAG), the aviation industry also provided strong support to the development and implementation of International Civil Aviation Organization (ICAO)’s Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), a landmark agreement, adopted at the last ICAO Assembly in October 2016, making the aviation industry the first sector to adopt a global market-based measure to address climate change.[1]

Governments agreed the world’s first global market mechanism for any single sector – the ICAO Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) will start to offset the increase of international aviation emissions from 2021, as compared to the baseline level of 2019 and 2020 average emissions.

In June 2018, the ICAO Council adopted global Standards and Recommended Practices (SARPs), guidance, and tools for a robust Monitoring, Reporting and Verification (MRV) system for international aviation CO2 emissions under CORSIA, which will be implemented by Member States and aeroplane operators from 1 January 2019. In addition, ICAO is continuing its work for the determination of eligible emissions units that aeroplane operators can use to meet their offsetting requirements under CORSIA.

Partners and Signatories

ICAO represents 192 member states and ATAG represents 29 private sector companies or associations from the aviation industry.
