Delta Airlines has reportedly removed two key environmental targets from its sustainability webpage, including a pledge to use sustainable aviation fuel (SAF) for 10% of its jet fuel needs by 2030. The company has also rephrased its goal of achieving net-zero emissions by 2050 to now depict it as an 'aspiration' rather than a firm target.

Why it matters

The airline industry has long viewed SAF as a critical solution to reduce carbon emissions, but the slow development and high costs of SAF have made it difficult for airlines to meet their ambitious sustainability goals. Delta's decision to scale back its 2030 SAF target reflects the broader challenges the industry faces in decarbonizing air travel.

The details

According to reports, a Delta spokesperson cited the 'slow development' of SAF as the reason for removing the 10% SAF target by 2030. SAF remains two to five times more expensive than conventional jet fuel, and there are also shortages of efficient new aircraft and alternative fuels that are pushing up profits for suppliers and putting the industry's emissions reduction goals at risk.

  • Delta updated its sustainability webpage in April 2026.

What’s next

Delta has not provided a timeline for when it may revisit or reinstate its 2030 sustainable aviation fuel target.

The takeaway

Delta's decision to scale back its sustainability goals reflects the broader challenges the airline industry faces in transitioning to lower-emission fuels and technologies. The slow development and high costs of sustainable aviation fuel remain major obstacles to the industry meeting its ambitious climate targets.
