King County recently announced plans to significantly increase the amount of biodiesel fuel used by Metro buses. Metro’s current biodiesel blend contains 5% biodiesel and 95% Ultra Low Sulfur Diesel. The goal is to increase the percentage of biodiesel to 20%, in support of the county’s intention to “cut pollution, reduce our dependence on foreign oil and encourage growth in the domestic clean-fuel industry.”

No word yet on a timeline, but your friendly neighborhood bus chick is on the case.
