CORSIA will begin in 2021 with a voluntary pilot phase that will last until 2023. During this phase airlines must compensate any additional emissions compared with the baseline years of 2019-2020 for routes between ICAO states participating in CORSIA.
Due to the COVID-19 pandemic, ICAO has decided to use only the year 2019 as the baseline period in the initial phase of CORSIA, lasting from 2021 to 2023. Which years will be included in the baseline period in subsequent phases will be considered as soon as it is clear what impact the COVID-19 pandemic has had on the aviation industry and CORSIA.
The scope of CORSIA is defined in European law in the delegated act (EU) 2019/1603.
Airlines with obligations under CORSIA are those which meet both of the following conditions:
- Hold an aircraft operator certificate issued by a Member state or registered in a Member state, including in the outermost regions, dependencies and territories.
- Produce annual CO2 emissions greater than 10 000 tonnes from the use of aeroplanes with a maximum certified take off mass greater than 5700kg conducting flights falling under the scope of CORSIA from 1 January 2019.
The flights falling under the scope of CORSIA are flights between:
- Aerodromes located in different states in the European Economic Area (EEA);
- Aerodromes located in Member states and aerodromes located in third countries;
- Aerodromes located in Member states and aerodromes in outermost regions, dependencies or territories of other Member states;
- Aerodromes located in outermost regions, dependencies or territories of Member states and aerodromes located in third countries or dependencies or territories of other Member states
- Aerodromes located in two different third countries (recommended).
Emissions from state flights, humanitarian flights, medical flights, military flights and firefighting flights are exempted .
Submitting the monitoring plan
In order to determine the amount of emissions generated in 2019 and 2020 all airlines with obligations under CORSIA must monitor and report their emissions from flights falling under the scope of CORSIA. The European Commission has created a dedicated monitoring plan template (nr.2bis) for the monitoring of emissions for both CORSIA and EU-ETS.
Monitoring rules for CORSIA
The monitoring rules for CORSIA are defined in the SARPS. The rules are however not directly enforceable and have been translated into European law by the European Commission through the delegated regulation (EU) 2019/1603. The same monitoring rules apply for the monitoring of CORSIA flights as apply for the EU-ETS for flights between countries within the EU and between EU countries and third countries. It is recommended to use the same monitoring method for your CORSIA flights between third countries. The monitoring plan template provides further information on how to monitor your CORSIA flights. You can find further information on this topic here.
Reporting for CORSIA
The European Commission will publish a dedicated reporting template for the reporting of emissions for both CORSIA and EU-ETS in January 2020. Airlines with obligations under CORSIA must report their 2019 CORSIA emissions by 31st March 2020 at the latest using the provided template.
In their verification, verifiers must use the verification report format drawn up by the European Commission. The verification report for the combined CORSIA & EU-ETS is the same template as for the EU-ETS. Although the EU-ETS and CORSIA emissions are reported in a combined reporting template, a separate verification report must be issued for the EU-ETS emissions and for the CORSIA emissions.
During the baseline years of 2019 and 2020 there is no requirement to monitor the number of offsetting flights or to surrender any offsetting credits.
