States Agree Not to Set Targets as ICAO Unveils Its Long-Term Vision on Sustainable Aviation Fuels Deployment
(GreenAir Online) ICAO concluded its second Conference on Aviation and Alternative Fuels (CAAF/2) held in Mexico City with an agreement on a long-term vision for the development, production and supply of sustainable aviation fuels (SAF) through to 2050. Delegates from Member States, industry and environmental groups had initially been asked to support ICAO’s Vision 2050 proposals for short, mid and long term goals that would ensure a 2% share of SAF in international aviation fuel demand by 2025, rising to 32% in 2040 and 50% by 2050. However, a number of States, along with industry and NGOs, failed to back the setting of targets and the conference settled instead for wording that calls for a “significant percentage” of SAF by 2050. The aviation industry said it welcomed the emphasis on developing robust sustainability criteria as a central component of alternative aviation fuels deployment.
Given accepted significant uncertainties in predicting the long-term contribution of SAF, ICAO’s Committee on Aviation Environmental Protection (CAEP) evaluated 120 SAF deployment scenarios for 2050, taking into consideration the global availability of resources, economic conditions, financial investments and policy decisions required to reach the assessed levels of global SAF production. The associated CO2 emissions reductions were calculated for each scenario.
The short-term goal of 5 Mt per year of SAF by 2025 is considered by the ICAO Secretariat as a “reasonable assumption”, based on current off-take agreements reached by airlines with biofuel producers of around 0.9 Mt per year. It sees recent policy decisions in countries like Norway, India, France and the UK to end the sale of gasoline and diesel cars by or before 2040 as driving large quantities of ‘green diesel’ – a current global capacity of 3.45 Mt/year – from road transport towards the aviation sector.
The Secretariat also believes international agreement on the SAF sustainability criteria under the ICAO CORSIA carbon offsetting scheme will address some of the uncertainties faced by industry and foster confidence in SAF investment. READ MORE
