The City of Asheville, N.C., cut its carbon footprint by 4.5% from the prior year largely due to switching from B-5 to B-20 biodiesel for its city and transit vehicles, according to the Citizen-Times.

Use of B-20 accounted for 40% of the year’s carbon footprint improvement, according to the city’s interim sustainability officer.

The city met its goal to reduce carbon emissions by 4% annually.
