Certification Scheme: ISCC CORSIA

CORSIA, the Carbon Offsetting and Reduction Scheme for International Aviation, is an emission mitigation instrument to address the increase in total CO2 emissions from aviation. It has been developed by the International Civil Aviation Organization (ICAO) and is the first Global Market Based Measures (MBM) scheme for an industry sector. ICAO Member States have set ambitious targets to mitigate greenhouse gas emissions from air transportation, including carbon-neutral growth from 2020 (baseline: 2019 emissions) and a 50% reduction of net aviation carbon emissions by 2050. 104 states (including all EU Member States), representing around 80% of international aviation, participate in CORSIA. Hence, the majority of airlines will be affected by the emission mitigation scheme. The Council of ICAO establishes and maintains international Standards and Recommended Practices (SARPs) that build a core aspect of ICAO’s mission and role and which are published in the form of Annexes. The first edition of Annex 16, Vol. IV, Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) has been adopted by the Council of ICAO on 27 June 2018 and became effective on 22 October 2018. Among other things, the Annex outlines COoffsetting requirements from international flights and the calculation of emissions reductions from the use of CORSIA eligible fuels. ISCC offers two options for certifying CORSIA eligible fuels: ISCC CORSIA and ISCC CORSIA PLUS.

For a general overview of CORSIA, ICAO has published a comprehensive series of brochures and leaflets.
