Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA)
The Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) is an initiative to control greenhouse gas emissions in the civil aviation sector. This measure, established by the International Civil Aviation Organization (ICAO), mandates that international airlines exceeding the specified greenhouse gas emission targets must purchase carbon credits to offset the excess emissions.
Origin of CORSIA
CORSIA was initiated following the 38th ICAO Assembly in 2013, which resolved that global aviation industry CO2 emissions must peak by 2020 and be maintained at or below that level thereafter.
Implementation in Thailand
Thailand voluntarily joined CORSIA in 2021. In 2022, the Civil Aviation Authority of Thailand (CAAT) issued regulations on the measurement and reporting of CO2 emissions in aviation activities. Airline operators are required to collect and report fuel consumption data and overall air traffic statistics annually to CAAT, following the specified format and guidelines.
For airline operators with international flights where aircraft have a maximum takeoff mass greater than 5,700 kilograms, an initial assessment of annual CO2 emissions must be conducted and submitted along with supporting documents to CAAT. Additionally, operators with international flight CO2 emissions exceeding 10,000 metric tons per year for aircraft with a maximum takeoff mass greater than 5,700 kilograms must draft a monitoring plan and report emissions in compliance with the approved monitoring plan.
