A New Step in Global Aviation Climate Accountability
The recent update to the ICAO document on the CORSIA Annual Sectors Growth Factor provides an important signal for the future of international aviation. The revised material, released in December 2025, outlines how the sector will calculate its 2024 growth factor. This factor is central to determining the amount of carbon dioxide emissions that operators need to offset under the global scheme.
What the Update Highlights
The document notes a clear comparison between total emissions in 2024 and the established baseline year of 2019. The updated Sector Growth Factor for 2024 is 0.15405257, a value that reflects the difference between current emissions and 85 percent of the 2019 total. This method supports transparency and gives States a consistent way to assess their offsetting requirements.
The update also aligns the calculation approach with Annex 16 guidance, ensuring that technical accuracy supports broader environmental goals. As participation now includes 126 States, the sector continues to move toward more unified climate action.
Why This Matters for the Sustainability Community
The growth factor is more than a number. It serves as a signal of how quickly the aviation sector is recovering and how urgently climate efforts must accelerate. It also reinforces the value of reliable data systems, consistent reporting, and credible offset pathways.
Organisations focused on sustainability can use this as an opportunity to strengthen their advisory role, guide clients through compliance clarity, and encourage innovation in emissions reduction strategies.
Conclusion
This update marks another important step in strengthening climate accountability across global aviation. It invites sustainability professionals to translate regulatory signals into practical action that advances long term climate goals.
