Biodiesel Blend Mandate
Pursuant to state law, all diesel motor vehicle fuel and all other liquid fuel used to operate motor vehicle diesel engines in Massachusetts must contain at least 2% renewable diesel fuel by July 1, 2010; 3% renewable diesel fuel by July 1, 2011; 4% renewable diesel fuel by July 1, 2012; and 5% renewable diesel fuel by July 1, 2013. For these purposes, eligible renewable diesel fuel includes diesel fuel that is derived predominantly from renewable biomass and yields at least a 50% reduction in life cycle greenhouse gas (GHG) emissions relative to the average life cycle GHG emissions for petroleum-based diesel fuel sold in 2005. The Massachusetts Department of Energy Resources (DOER) must also study the feasibility, benefits, and costs of applying the percentage mandates on a statewide average basis rather than for every gallon of diesel motor fuel sold.
DOER may delay the implementation of the biodiesel blend mandate if DOER determines that it is not feasible to meet the mandate due to lack of supply, lack of blending facilities, or unreasonable cost. As of June 2010, DOER suspended the formal requirement on grounds of unreasonable cost.
