The City of Seattle would reduce fleet greenhouse-gas emissions by 50% by 2025 by using electric vehicles as well as renewable diesel and biodiesel under a new plan announced by Mayor Ed Murray.

The plan, known as Drive Clean Seattle, would also attempt to reduce air pollution caused by city residents and businesses by setting a goal to have 15,000 electric vehicles on city roads by 2025.

The city has also enlisted commercial fleets in the initiative. MacDonald-Miller Facility Solutions, a mechanical contractor in the Northwest, has agreed to continue adding electrified vehicles to its fleet.

"MacDonald Miller has made conversion to electric vehicles a priority for our fleet," said Bruce Birdsell, the company’s fleet manager. "Mayor Murray’s Drive Clean Seattle initiative will create the infrastructure necessary for our continued conversion, saving carbon emissions from our transportation fleet as we continue to help our customers save carbon emissions through building energy efficiency.”

Other planned initiatives include tripling the number of fast-chargers in the city. Seattle City Light will also launch a pilot program to support residential charging stations though on-bill repayment and time-of-day pricing.

The plan is taking aim at public transportation by attempting to boost the "electrified transportation economy," according to a release from Murray's office. Earlier this year, BMW launched its DriveNow car-sharing service that uses ActiveE and i3 electric vehicles to compete with Car2Go.

The city is working with King County Metro and Sound Transit to "identify opportunities to continue to use our clean electricity as a transit fuel."
