CORSIA: Who needs to be participating in the scheme?

Following the brief introduction on CORSIA and its impact on airlines, you probably wonder if you need to be participating in the scheme. In this article, we will focus on understanding which states and airlines are involved.

 

Are all states concerned by CORSIA?

Starting in 2019, 73 voluntary states will implement CORSIA. These 73 states represent 87.7% of international aviation activity. Those voluntary states will gain more experience and enable the carbon market to adapt more quickly to the raising demand of offsets.

You can find the list of the 73 voluntary states on ICAO's website.

 

The rest of the world will start to implement CORSIA in 2027, when the mandatory phase starts.

 

However, there will be some states exempted, if they comply with one of the criteria:

  • Aviation criteria: less than 0.5% of total Revenue tonne kilometers (RTKs) or after 90% of cumulative RTKS (by classifying states from the highest to the lowest contributors).
  • Social-economic criteria: LCDs (Least Developed Countries), SIDs (Small Island Developing States), LLDCs (Landlocked Developing Countries)

 

Which airlines are concerned by CORSIA?

 

Right from the start, in 2019, ALL AIRLINES need to start monitoring and reporting their emissions. Even airlines based on a non participating state are required to monitor and report all their flights.

 

You may be surprised and wonder why?

 

For the baseline to be correct, all flights should be reported in 2019-2020.This will enable the baseline to be adaptive to the new states joining the scheme. Reporting flights from or to non-participating states is therefore very important because they will be considered when the state starts participating.

 

Moreover, even if you are based in a non-participating state, if you are operate flights between two participating states, you will need to offset your emission for the flights on those routes.

Remember:

  • Reporting scope: ALL international civil flights
  • Offsetting scope: Covered route (routes between participating states)

 

What is the risk if airlines do not report their 2019-2020 emissions?

 

Since the baseline is the limit over which emissions will need to be compensated, a low baseline due to airlines not reporting in 2019-2020 will only increase the compensation from 2020-onwards.
