During the United Nations (UN) Climate Action Summit  held on 23 September 2019 at UN Headquarters in New York, the UN Secretary-General called on all leaders to elaborate concrete, realistic plans to enhance and communicate their plans to reduce greenhouse gas emissions by 2050. The Summit served as a public platform for Member States, as well as finance, business, civil society and leaders from public and private sectors. Nine action portfolios, recognized as having high potential to curb greenhouse gas emissions and increase global action on adaptation and resilience, were prioritized, including: finance; energy transition; industry transition; nature-based solutions; cities and local action; resilience and adaptation; mitigation strategy; youth engagement and public mobilization; and social and political drivers.


ICAO participated in the UN Climate Summit, as part of cooperation with other UN bodies, with the aim of maintaining ICAO’s leadership role related to international aviation and climate change. At various events in conjunction with the UN Climate Summit, ICAO highlighted the decisions and important achievements to date in addressing international aviation CO2 emissions, and the importance of partnerships among ICAO Member States, aviation industry and other stakeholders to accelerate the progress in the ICAO basket of measures to address international aviation CO2 emissions, using the UN Climate Summit’s approach of Coalitions for the advancement of climate actions.

Following the Assembly’s discussions and related decisions on the subject of international aviation and climate change, the ICAO Council will further discuss how to effectively implement the updated Assembly Resolution under close collaboration among the proposed global coalition partners – Member States, aviation industry and other stakeholders, toward the sustainable future for international aviation.


As part of the Coalition, the ICAO in-sector aviation CO2 emissions reduction initiatives tracker tool provides a variety of information related to initiatives to reduce the environmental footprint of aviation, including details on past and ongoing measures and initiatives.
