Definition of sustainable aviation fuel modified.

This bill modifies Minnesota's definition of sustainable aviation fuel under state law. It specifies that qualifying fuel must be derived from biomass, gaseous carbon oxides from biomass or direct air capture, or green hydrogen - excluding palm fatty acid distillates - and must achieve at least a 50% reduction in life cycle greenhouse gas emissions compared to petroleum-based fuels. The requirement uses either the Argonne National Laboratory's GREET model or the International Civil Aviation Organization's methodology for verification. This directly affects Minnesota taxpayers engaged in producing or blending sustainable aviation fuel. The change ensures state compliance with specific environmental standards for eligible fuel.
