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 2018, IATA conducted a series of workshops to help operators develop their CORSIA emissions monitoring plan and start the monitoring of emissions on 1 January 2019.  As we are committed to continuing to support operators throughout the different stages of compliance with CORSIA, in 2019, we will be holding a new series of workshops focused on emissions reports and verification.

The objective of the 2019 workshops is to help operators prepare for the verification of their emissions data and the submission of their emissions report. Through presentations and interactive group discussions, participants will go through the main requirements under CORSIA and identify potential risks related to the collection and reporting of fuel data. The workshops will also provide operators with information on the ICAO process and provide insight in IATA's FRED+ tool, a system developed by IATA to facilitate the reporting of emissions and minimize the associated administrative burden for both operators and administrating authorities.

  • CORSIA: where are we? recent developments in ICAO; main challenges; and preparation for the ICAO Assembly.
  • Reporting of emissions: overview of requirements and responsibilities: the emissions monitoring plan, timelines for compliance. ICAO CERT and templates; overview of FRED+
  • Data requirements: overview of data requirements; addressing data gaps; FRED+ data vault and data input
  • Report generation and submission: format, internal audit, verification and order of magnitude check; report generation in FRED+
