TOKYO -- Japan's campaign to cut greenhouse gas emissions is extending to the skies, as the government aims to have airlines replace 10% of their jet fuel with eco-friendlier alternatives by 2030.
Sustainable aviation fuels, or SAFs, are made from waste, biomass or scrap material. While they generate 70% to 90% less carbon dioxide than conventional jet fuel, they can cost up to 10 times as much to produce. The government plans to set up a public-private committee this year to consider specific measures to encourage Japanese companies to make and use these fuels.
