Is the Renewable Fuel Standard enough to spur progress in advanced biofuels? Probably not.

Production of cellulosic biofuel is expected to fall nearly 7 billion gallons short of meeting the statutory Renewable Fuel Standard (RFS) volume for this type of advanced biofuel in 2018, which has...Government grant and loan guarantees, not the Renewable Fuel Standard, have been essential in spurring progress in the cellulosic biofuel industry.

Bioenergy can solve some of our climate problems, but not all of them at once

Bioenergy has become a popular decarbonization strategy—so popular that policy makers and researchers in several sectors are claiming biofuels, bio-electricity, and bio-heat can deliver a large...Bioenergy has become a popular decarbonization strategy to reduce greenhouse gas (GHG) emissions. However, even if bioenergy production is maximized, competition across industry sectors is high.
