scope:

In accordance with Resolution A39-2, action plans should incorporate information on activities that aim to address CO₂ emissions from international aviation, including national actions, as well as activities implemented regionally or on a global scale as the result of bilateral and regional/multilateral agreements.

It should be noted that most aviation-related mitigation measures affect both domestic and international operations. To the extent possible, States should distinguish between domestic and international aviation data within their State Action Plan. The action plan should focus on international data, however, if a State wishes to highlight the impact of selected measures on domestic aviation, those impacts may be considered a supplemental benefit of ICAO's global aspirational goals.

Examples of supplemental benefits could include emissions from ground support equipment operations and airport-related ground transportation. These are considered domestic emissions and are beyond the scope of Resolution A39-2. However, if a State wishes to consider the aviation sector as a whole, these measures could be listed as relevant supplemental information to help explain their strategies.
