Some of the country's first gas-pump warning labels about climate change are coming to Berkeley, a city with a long history of green and clean policies.
The Berkeley City Council voted late Tuesday to draft a proposal by next spring that will put stickers on gas pumps citywide to warn consumers that burning fuel contributes to global warming.
San Francisco is drafting a similar ordinance that the city's Board of Supervisors could vote into law by March. The proposals in the liberal Bay Area cities are thought to be the first of their kind in the U.S.
Supporters of Berkeley's measure hope that simply putting the labels in front of consumers will motivate them to drive less. One environmental group compares the labels to health warnings on cigarette packages.
