The Biden Administration announced support for renewable fuels used as sustainable aviation fuel (SAF), a landmark decision providing a pivotal win for the ethanol and biodiesel industries. However, some uncertainty remains regarding requirements around SAF feedstocks. Ultimately, the global aviation industry is slated to profit a whopping $20 billion in 2023, accounting for about 2% of global carbon dioxide emissions.

The airline industry has long argued incentives are needed to switch to SAF, which generates 50% less greenhouse gas emissions than petroleum fuel but is at least twice as expensive. The Biden Administration has remained neutral on the topic for months. Farm groups have responded in favor, praising the President’s decision to support the Greenhouse Gases, Regulated Emissions and Energy Use in Technologies (GREET) model.
