So dumb.

SAN FRANCISCO (CBS SF) – A group of Bay Area environmentalists has proposed labels that will warn drivers of their contribution to global warming every time they pull up to the pump.

Similar to the Surgeon General’s warning on a pack of cigarettes, the proposed stickers would remind motorists of the State of California’s position that fossil fuels are leading to potentially hazardous climate change.

The labels are needed because, “There’s no immediate signal to a consumer of gasoline to show their effects on climate,” Jamie Brooks told the San Francisco Chronicle. Brooks represents, the group behind the proposal.

The Chronicle reports that the proposal is being proposed to individual city governments, and that San Francisco and Berkeley officials have already been approached about the idea. There was no timeline on when the labels could appear. If approved they would likely face legal challenges from the oil industry.
