Washington State’s Proposed Clean Air Rule Ignores Biofuels’ Climate Benefits

July 22, 2016


WASHINGTON Washington states proposed Clean Air Rule (CAR) fails to recognize the climate benefits associated with biofuels and in fact penalizes their use, the Renewable Fuels Association (RFA) told the Washington Department of Ecology in comments submitted today. The proposed rule is inconsistent with virtually every other program designed to reduce greenhouse gas emissions and could have the perverse effect of reducing or eliminating the production and use of liquid biofuels in Washington state. In an effort to address climate change, Washington state has proposed its first-ever rule to cap carbon pollution. The rule, which would take effect next year, would regulate a number of emissions, including those from biofuels. However, the CAR proposal eschews globally accepted bioenergy carbon accounting methods out of fear that properly recognizing the carbon benefits associated with biofuels would trigger the so-called poison pill legislative provision that would shift funding from climate-friendly transportation investments to road and highway construction projects, according to RFA comments. Analyses from the California Air Resources Board, Oregon Department of Environmental Quality, and U.S. Department of Energy show that first-generation ethanol is reducing greenhouse gas (GHG) emissions by 3060 percent compared to petroleum, while second-generation ethanol can reduce GHG emissions by 80 percent or more. Washington states proposal fails to recognize those clean air benefits from biofuels. The proposed CAR treats biofuels and fossil fuels identically, which sets a dangerous carbon accounting precedent with potentially far-reaching impacts, RFA wrote in its comments. Other GHG cap-and-trade programs exempt biofuels from a compliance obligation because it is broadly understood that bioenergy combustion emissions are carbon neutral (i.e., the biomass recently removed an amount of atmospheric carbon through photosynthesis that is equivalent to emissions from combustion). Curiously, Washington state seems to understand this point, as it exempts emissions from biomass combustion in stationary sources, such as the use of woody biomass to generate electricity. It is perplexing that this approach would be (properly) applied to stationary emissions from bioenergy production from biomass combustion, but not to emissions from liquid biofuel combustion, RFA wrote. Implementing the CAR as proposed would set a perilous regulatory precedent, deter investment in the states biofuels market, and compel reduced consumption of low-carbon biofuels, the comments continued. If implemented, developers of advanced biofuel technologies would avoid the Washington state market and instead shift focus on investments in California, Oregon, British Columbia and elsewhere. For these reasons we strongly urge the Department of Ecology to exempt biofuels from compliance obligation in the final CAR, RFA added. A full copy of RFAs comments is available here.
