CORSIA: CO2 management in aviation

20 April 2018 | Markets | 1

To keep aviation at the forefront of the environment, the International Civil Aviation Organization (ICAO) adopted the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA).

The main objectives of this plan are: the sector's carbon neutral growth from 2020 onwards and halving net emissions by 2050 compared to 2005 levels.

The rapid development of sustainable aviation fuels and the modernization of air traffic management are essential to achieve the objectives. However, at the same time, it is considered to be the instrument for offsetting emissions through CO2 certificates, as a possibility for achieving the objectives.

How will CORSIA be implemented?

As of 2019, all ICAO member states whose air operators operate international flights must measure, report and verify (MRV) the CO2 emissions of those flights.

CORSIA is divided into 3 phases, plus a preliminary design phase:

  • 2018-2020 design and reference phase: We are currently in the design phase in which air operators will establish their emissions monitoring and reporting plan (2018) to establish the reference CO2 emissions level (2019-2020).
  • 2021-2023 pilot phase: First three-year emissions measurement, report and verification cycle.
  • 2024-2026 first phase: 73 States, representing almost 90% of international aviation activity, will participate voluntarily.
  • 2027-2035 second phase: will apply to all non-exempt states, unless they decide to participate voluntarily.

The average CO2 emissions from international aviation between 2019 and 2020 will represent the baseline for carbon-neutral growth from 2020 onwards, against which emissions in the coming years will be compared.

For the phasing-in of CORSIA, aircraft operators should submit their Emission Monitoring Plan by 30 September 2018 at the latest.


Factor CO2 with a long history in the design and implementation of monitoring plans for CO2 emissions, will undoubtedly be a good ally in the implementation of CORSIA in your company.
