The idea of blending biodiesel into diesel fuel is not new in Minnesota. The law that requires a minimum of 10 percent biodiesel that started July 1 isn’t new, either. The original law was passed in 2008 — largely through the efforts of biodiesel stakeholders, the agriculture sector and even the trucking industry — to support local economies with a renewable replacement for diesel fuel. And the state has had a minimum blend of biodiesel for more than a decade, starting with B2 in 2002.
Because it was a big change — from a single fuel source in petroleum diesel — the law was written to be implemented in steps. Much care was given to ensure all the benefits of biodiesel could be achieved without adversely affecting Minnesota consumers or industries.
