Beyond the ICAO’s CORSIA: Towards a More Climatically Effective Strategy for Mitigation of Civil-Aviation Emissions
April 2018 – In a peer-reviewed research article published in the journal Climate Law, air transport economist Chris Lyle examines ICAO’s role in addressing international aviation’s growing emissions since referral by the UNFCCC to the UN agency through the Kyoto Protocol. He examines the ‘basket of measures’ developed by ICAO to mitigate emissions through to the adoption of a framework for a market-based measure that aims at carbon-neutral growth from 2020 onward. The Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) is to be the primary emission-mitigation tool for international aviation. However, even with an increased use of alternative fuels and CORSIA implementation, the ‘basket’ will not produce a reduction in global aviation emissions, he argues, and proposes a derivative but more ambitious strategy.
This would include incorporation of international aviation emissions in the Nationally Determined Contributions (NDCs) of parties to the Paris Agreement and a more direct role for the UNFCCC in determining eligibility of emission units and alternative fuels, with ICAO remaining accountable for monitoring, reporting and verification.
