by Patrick Newkumet (OPIS) Alternative low-carbon fuel producers would receive tax credits for reaching net-zero emissions under a U.S. Senate bill introduced last month, but biofuel industry stakeholders are concerned they will find it difficult to reach that target by 2030 unless the government revises its count of the carbon intensity (CI) of their fuels to what they say would be a more accurate and lower number. Under the Clean Energy for America Act, introduced by Senate Finance Committee Chairman Ron Wyden (D-Oregon) on April 21, tax breaks for fossil fuels would be replaced with a technology-neutral tax break for producers whose fuels have zero or negative carbon emissions.
