The U.S. Conference of Mayors, while meeting this weekend in Miami, adopted a resolution challenging use of high-carbon fuels — such as tar sands, liquid coal, and oil shale — and calling for the creation of guidelines and purchasing standards to help mayors understand the greenhouse-gas emissions of the fuels they buy.
The resolution was submitted by Mayor Kitty Piercy of Eugene, Ore., and was co-sponsored by 10 other mayors from across the nation, including Gavin Newsom of San Francisco, Jennifer Hosterman of Pleasanton and Beverly Johnson of Alameda.
The mayors noted these fuels come from hardt-to-access, lower-grade raw materials, and production can emit two to five times more global warming pollution than conventional oil.
Natural Resources Defense Council senior attorney Susan Casey-Lefkowitz said U.S. mayors in recent years have been becoming vital leaders in the war on global warming. “Mayors see their residents’ needs every day, and they see the impact that global warming is going to have on their cities. That’s why over 850 mayors across the nation already have taken action on climate change. This resolution will help implement their commitment to fight global warming by giving mayors the information they need about dirty fuels such as tar sands oil.”
