Resolution text for GMBM to be adopted for aviation CO2 emission control

At Montreal, on October 6, the Plenary Session of the UN aviation agency’s 39th Assembly agreed to adopt a global market-based measure (GMBM) to control international aviation’s CO2 emissions.
According to ICAO Council President, Dr. Olumuyiwa Benard Aliu, “It has taken a great deal of effort and understanding to reach this stage, and I want to applaud the spirit of consensus and compromise demonstrated by our Member States, industry and civil society. We now have practical agreement and consensus on this issue backed by a large number of States who will voluntarily participate in the GMBM – and from its outset. This will permit the CORSIA to serve as a positive and sustainable contributor to global greenhouse gas emissions reduction.”
ICAO’s Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) has been designed to complement the raft of mitigation measures the air transport community is already following to reduce international aviation CO2 emissions, including technical and operational improvements, along with advances in the production and use of sustainable alternative aviation fuels.
A pilot phase will begin with the implementation of the CORSIA from 2021 through 2023 will be followed by a first phase, from 2024 through 2026. Participation in both phases will be voluntary, after which the next phase from 2027 to 2035 will see all states on board. Certain exemptions have been made for Least Developed Countries (LDCs), Small Island Developing States (SIDS), Landlocked Developing Countries (LLDCs) and States with very low levels of international aviation activity.
Dr. Fang Liu, Secretary General of ICAO is quoted as saying: “I would like to thank all those who have been part of this process. This Resolution is the reflection of the spirit of cooperation and tremendous efforts. The ICAO GMBM endorsed today is an important addition to the basket of measures aviation is pursuing to address CO2 emissions.”
