International Climate Action in Civil Aviation

Source: ET

 Context: India will start participating in the International Civil Aviation Organisation’s (ICAO) Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) and the Long-Term Aspirational Goals (LTAG) in 2027.

About ICAO

The International Civil Aviation Organization (est. 1944; HQ: Montreal, Canada) is a specialized agency of the United Nations that coordinates the principles and techniques of international air navigation and fosters the planning and development of international air transport to ensure safe and orderly growth.

It has adopted ambitious goals of: 2% annual fuel efficiency improvement through 2050; carbon neutral growth and net zero by 2050. The ICAO has clubbed them under CORSIA and LTAG.



CORSIA (Carbon Offsetting and Reduction Scheme for International Aviation) is a global scheme established by the ICAO to address the growth in CO2 emissions from international aviation.
Purpose To mitigate the growth of carbon emissions from international aviation by offsetting and reducing emissions
Scope Applies to international flights only
Timeline Phase 1 (2021-2023) – voluntary participation by states; Phase 2 (2024-2026) – mandatory participation for certain states based on size of their aviation industry; Phase 3 (2027-2035) – mandatory participation for all states
Offsetting Airlines will offset their emissions by purchasing credits from approved carbon offset projects
Criteria for offset projects Must meet certain criteria, such as being added to any other efforts to reduce emissions, being verifiable, and not causing harm to local communities or ecosystems
Review process The scheme will be reviewed every three years to ensure effectiveness and make necessary adjustments
Goals CORSIA aims to achieve carbon-neutral growth for international aviation from 2020 onward and reduce CO2 emissions from international aviation by 50% by 2050 compared to 2005 levels.

What are Long-Term Aspirational Goals (LTAG)?

It is an initiative of the ICAO to achieve net-zero carbon emissions from international aviation by 2050. It does not attribute specific obligations or commitments in the form of emissions reduction goals to individual States but each state will contribute within its own national timeframe
