As you may have seen in the news, a recent PNAS article by Tyler Lark contains wildly overstated and speculative claims about the environmental impact of biofuels, in particular the relationship between the RFS and greenhouse gas (GHG) emissions.

As has been shown repeatedly, there is simply no evidence that the RFS increases GHG emissions on a lifecycle basis, compared to gasoline.

Quite the opposite, plant-based, cleaner-burning biofuels provide almost 50 percent lifecycle GHG emission reductions compared to gasoline. Further claims that have sought to tie the RFS to impacts to wildlife have been thoroughly disproven.

In addition, to claim that the RFS is a driver of land use change is wholly unsupported by the evidence.

The total acreage of land devoted to corn agriculture has remained unchanged for nearly a century, and to claim that the RFS somehow drives corn prices and land use change is just simply untethered from reality.

We’ll continue to set the record straight on these inaccurate claims and let the science speak for itself when it comes to the many climate and environmental benefits of biofuels.
