If international aviation were a country, it would be a global top-ten carbon emitter, with emissions expected to triple or quadruple by 2040. This is why the International Civil Aviation Organization (ICAO) has agreed to cap net carbon emissions from international aviation at 2020 levels.
ICAO aims to achieve this goal through technical and operational measures; carbon pricing through market-based measures (MBM’s); and biofuels. Many airlines see biofuels as a “silver bullet” for meeting their carbon goals. Already over 40 airlines have flown over 600,000 biofuel-powered flights.
Biofuels: aviation's silver bullet?
ICAO established the Alternative Fuels Task Force (AFTF) to answer the key question: how much do biofuels actually reduce greenhouse gas (GHG) emissions? The AFTF is close to finalizing its answer. EDF, WWF-UK and our colleagues in the International Coalition for Sustainable Aviation are working to secure an MBM of high environmental integrity for international flights. Getting biofuel carbon accounting right is vital. If biofuels reduce carbon pollution, then airlines’ obligations under the MBM will decrease. But if biofuels increase carbon pollution, then airlines’ MBM obligations will increase. Read More
