JetBlue is taking back its 2020 promise to offset greenhouse gas pollution from its domestic US flights and will instead focus on cutting its per-seat pollution in half by using “sustainable aviation fuels” generated from waste or plants. The aviation sector is responsible for a massive amount of climate pollution, made even worse by the lack of high speed rail in the U.S., but carbon offsets and the flashy purchasing thereof, have been shown to rarely reduce real-world pollution and can perpetuate devastating exploitation of Indigenous land and resources. Early last year, United Airlines also decided against buying carbon offsets, opting instead to invest in CCS efforts. (The Verge, Reuters, Bloomberg $)
