Carbon Offsetting Scheme for International Aviation (CORSIA)


CORSIA, the Carbon Offsetting and Reduction Scheme for International Aviation, addresses the increase in total CO2 emissions from international aviation above 2020 levels. 

CORSIA’s obligations have already started. As of 1 January 2019, all carriers are required to report their CO2 emissions on an annual basis.

The aviation industry is committed to technology, operational and infrastructure advances to continue to reduce the sector's carbon emissions. Offsetting is not intended to replace these efforts. Nor would the CORSIA make fuel efficiency any less of a day-to-day priority. 

It is forecast that CORSIA will mitigate around 2.5 billion tonnes of CO2 and generate over USD 40 billion in climate finance between 2021 and 2035.

About Support Workshops

CORSIA Workshops

In 2019, IATA conducted a series of workshops to help operators prepare for the verification of their emissions data and the submission of their emissions report in early 2020. Through presentations and interactive group discussions, participants went through the main requirements under CORSIA and the potential risks related to the collection and reporting of fuel data. 

Upcoming workshops

  • Mexico City, 20-21 November 2019, hosted by Aeromexico
