Delta Air Lines has quietly adjusted its environmental commitments, removing or rephrasing key climate targets from its official sustainability website. According to a Bloomberg News report released on Tuesday, the Atlanta-based carrier has deleted its pledge to power 10% of its operations with sustainable aviation fuel (SAF) by 2030.
Furthermore, the airline has altered the language surrounding its long-term environmental vision. The previous “goal” of achieving net-zero emissions by 2050 has now been reclassified as an “aspiration.”
While SAF is considered a vital tool for decarbonising the aviation industry—offering significant emission reductions compared to traditional kerosene—the market remains constrained. The fuel currently costs between two and five times more than conventional alternatives, and supply levels remain critically low.
A spokesperson for Delta reportedly stated that while the airline still views SAF as a primary lever for decarbonisation, the slow pace of development across the sector threatens the industry’s broader climate ambitions.
The move follows warnings from the International Air Transport Association (IATA) regarding the difficulty of meeting global aviation targets. In February, IATA Director-General Willie Walsh noted that shortages of efficient new aircraft and alternative fuels are putting the industry’s flagship emissions goals at risk.
