ICAO joins the commemoration of this day by highlighting its work on aviation and local air quality. ICAO serves as a multilateral platform for cooperation on international aviation environmental protection. Over the years, the national governments who participate together under the Chicago Convention, also commonly referred to as ‘ICAO Member States’, have agreed to concentrate their aviation environmental collaboration on three core areas: Climate change and aviation emissions Aircraft noise Local air quality Countries are pursuing these objectives through ICAO primarily via their development of new global aviation standards. They have also agreed to aspirational goals for international aviation, and have prioritized ICAO’s Environmental Protection resources on: Airframe, propulsion, and other aeronautical and technological innovations Optimizing flight procedures to reduce fuel burn Increasing the production and deployment of sustainable aviation fuels and clean energy Implementing the Carbon Offsetting Reduction Scheme for International Aviation (CORSIA).
