Long a leader in environmental regulation, California is pushing to reduce greenhouse gas emissions from automotive fuels. At the center of this effort is the state’s low carbon fuel standard (LCFS), which promotes the use of biofuels that have a gentler climate impact than gasoline. Now, a new report from California’s air regulators shows the LCFS is ahead of schedule in ratcheting down the amount of carbon in fuels. But this progress could be countered by the Trump administration, which last week recommended reducing federal mandates for the most advanced low-carbon biofuels. The administration’s budget has also proposed eliminating funds for the Department of Energy program responsible for funding most of the research on novel low-carbon fuels.
