USDA finalizes guidelines for measuring carbon intensity of biofuel crops

The Agriculture Department has issued a final rule establishing technical guidelines for calculating the greenhouse gas emissions associated with growing crops used as fuel. This rule updates an interim version from January 2025 and creates a standardized way to measure how much carbon dioxide is emitted per bushel of corn, soybeans, sorghum, or canola produced under specific low-carbon practices.

Why it matters: This rule matters primarily for producers of biofuel feedstocks who want to participate in emerging markets that reward lower-carbon agricultural practices. By standardizing how emissions are calculated, it allows buyers and regulators to verify that crops were grown using methods that reduce greenhouse gas output. It does not create new taxes or mandates but provides the data framework needed for voluntary environmental services markets.

Who it affects

• Farmers and ranchers growing field corn, soybeans, sorghum, or spring canola who use low-carbon practices
