Washington may require more climate-friendly motor fuels

The Washington Legislature is considering whether to require use of more climate-friendly motor vehicle fuels. Although Washington collects and processes biodiesel – an alternative fuel made partially of vegetable oil or animal fats that has a distinctly lower carbon impact than traditional diesel – most of this renewable resource is shipped out of state because Oregon, California, and British Columbia have all passed legislation requiring progressive reductions in the amount of fossil fuel allowed in gasoline and diesel.
