Political posturing from a small segment of the petroleum industry has the Trump administration considering damaging changes to our most successful American energy policies that we’ve seen in decades: the renewable fuel standard. The RFS was passed by a bipartisan Congress and signed into law by President George W. Bush more than a decade ago, provides an avenue for domestic biofuels producers to gain access to the U.S. transportation fuels market, which has been monopolized by the petroleum industry for more than a century. The results of the program have been impressive. Americans now enjoy the benefits of increased jobs, economic growth in rural America, and more clean-burning fuels like biodiesel being used in school buses, emergency vehicles, and trucking fleets across the country. That is success worth celebrating.
