Establishes low-carbon transportation fuel standard program in DEP.

S 2425 requires gasoline and diesel suppliers in New Jersey to reduce the average greenhouse gas emissions per unit of fuel by 10% below 2019 levels by 2030. The law establishes a credit trading system where producers meeting the standard earn tradable credits to offset deficits from fuels that exceed the standard. It applies to refiners, wholesalers, importers of gasoline and diesel, and alternative fuel producers who choose to participate. Emissions are measured using a life-cycle analysis covering all stages of fuel production and use.
