The city of Berkeley is considering putting stickers on gas pumps citywide to warn consumers that burning fuel contributes to global warming. The Berkeley City Council was set to vote to possibly move forward by early next year with the proposal, among the first of its kind in the U.S. Supporters of the gas pump measure hope that simply putting the labels in front of consumers will motivate them to drive less. However, there is criticism elsewhere. Many oil and gas companies feel the plan imposes a burden on their businesses. Berkeley Chamber of Commerce Chief Executive Officer Polly Armstrong said, 'We are in the business of helping businesses in Berkeley, and some of the people on the council seem to be working in the opposite direction,' Armstrong said. 'In terms of putting stickers on gas pumps, I would argue that the people in Berkeley are really smart and they know about gasoline (impacts).'
