The House Energy and Commerce Committee wrapped up the comment period May 24 for its third white paper on the environmental impacts of the renewable fuel standard. The American Petroleum Institute commented that the standard would increase nitrogen oxides and particulate matter emissions; the Biotechnology Industry Organization said emission reduction will continue to improve as technology improves; and the Renewable Fuels Association responded that the standard is reducing emissions compared to baseline petroleum. The committee’s first white paper examined the ethanol blend wall while the second paper reviewed the impact on the agricultural sector.
