On August 7, 2014, a group of nine Democratic Senators led by Senator Tom Harkin (D-IA) sent a letter to the EPA Administrator, Gina McCarthy, on the treatment of biogenic carbon emissions from stationary sources. The other eight Senators who signed the letter are: Tim Johnson (D-SD); Heidi Heitkamp (D-ND); Ron Wyden (D-OR); Maria Cantwell (D-WA); Al Franken (D-MN); Patty Murray (D-WA); Joe Donnelly (D-IN); and Amy Klobuchar (D-MN). The letter comes at a time when EPA is working to issue in final a rulemaking providing guidelines for such treatment.
In their letter, the Senators caution that treating biogenic carbon emissions in the same way as fossil fuel emissions could negatively impact the development and commercialization of advanced biofuels, biopower, renewable chemicals, and other industrial biotechnologies. They urge EPA to recognize in its treatment of biogenic carbon emissions that "carbon emissions resulting from the utilization of sustainably-sourced, renewable biomass feedstocks do not result in lasting increases in atmospheric carbon dioxide, and therefore should not be subject to greenhouse gas regulations."
