Most discussions about biofuels center on ethanol, but biodiesel—a diesel-substitute made from vegetable oils and animal fats—is increasingly important as well. But where does biodiesel come from, and what does it mean for the climate? Like most important things, the answers aren’t black or white—but they’re critical to get right. Read more >

At the end of October I went to Iowa for the grand opening of DuPont’s cellulosic ethanol facility. It will be the largest of its kind in the world, ultimately producing 30 million gallons of ethanol from corn stalks annually. This important milestone is a fruit of the much maligned Renewable Fuel Standard, or RFS, a policy passed in 2007 that is the subject of many misleading TV ads from the oil and ethanol industries airing in DC and elsewhere. It may come as no surprise that more valuable insight about our clean fuel future is being developed inside the factory than is available on political ads.

There are no quick or easy answers, but the Environmental Protection Agency’s (EPA) proposal to get the Renewable Fuels Standard back on track is balanced and flexible. It will take more than one rulemaking process to clean up our fuel system, but the EPA’s proposal is a good start, helping accelerate the transition from oil to clean, renewable alternatives.

Interview with Harvard’s James Stock: Navigating a Sensible Middle Path Forward on the Renewable Fuel Standard

Earlier this month I had the chance to sit down with Professor James Stock of Harvard University to discuss the future of biofuels and the key federal policy governing them, the Renewable Fuels Standard (RFS).
Professor Stock served as a member of President Obama’s Council of Economic Advisors in 2013 and 2014. He was deeply involved in deliberations about the RFS during his tenure, and it was in that context that I first met him, back in October 2013, when I went to the White House to offer perspective on how best to implement the RFS.
