Vastly lowered emissions. Biodiesel meets California's strict CARB standards. Because biodiesel is derived from plants, it has a complete carbon cycle - burning biodiesel emits about as much carbon as was absorbed by the plant when it was alive. In May 2000, biodiesel became the only alternative fuel in the country to have successfully met the EPA's Tier I and Tier II Health Effects standards under Section 211(b) of the Clean Air Act. Biodiesel mixes cleanly at any ratio with petrodiesel-- in fact, adding only a small amount of biodiesel to petrodiesel results in greatly lowered emissions.
