Hopes For Sustainable Jet Fuel Not Realistic, Report Finds
Hopes that replacement fuels for airplanes will slash carbon pollution are misguided and support for these alternatives could even worsen the climate crisis, a new report has warned. The Guardian: There is currently "no realistic or scalable alternative" to standard kerosene-based jet fuels, and touted "sustainable aviation fuels" are well off track to replace them in a timeframe needed to avert dangerous climate change, despite public subsidies, the report by the Institute for Policy Studies, a progressive thinktank, found. "While there are kernels of possibility, we should bring a high level of skepticism to the claims that alternative fuels will be a timely substitute for kerosene-based jet fuels," the report said. Chuck Collins, co-author of the report, said: "To bring these fuels to the scale needed would require massive subsidies, the trade-offs would be unacceptable and would take resources aware from more urgent decarbonization priorities. It's a huge greenwashing exercise by the aviation industry. It's magical thinking that they will be able to do this." In the US, Joe Biden's administration has set a goal for 3bn gallons of sustainable aviation fuel, which is made from non-petroleum sources such as food waste, woody biomass and other feedstocks, to be produced by 2030, which it said will cut aviation's planet-heating emissions by 20%.
