To do its part to avert catastrophic climate change, the United States would have to eliminate carbon emissions from transportation in the next 35 years. But America is nowhere near on pace to make that happen.
Transportation recently overtook the electric power sector to become the nation’s largest source of carbon emissions. That’s what you would expect out of a transportation policy framework that prioritizes cars, highways, and sprawl — and hasn’t changed very much in 60 years, despite some recent tinkering around the margins.
The U.S. Public Interest Research Group and the Frontier Group are out with a new report [PDF] outlining 50 steps to eliminate carbon pollution from the American transportation sector by incentivizing low-carbon modes of travel, more efficient development patterns, and cleaner vehicles. Here are three of the most important steps.
First step — get a grip on the damage being done
America is basically flying blind when it comes to charting a greener course for transportation emissions — we have no idea how all the money spent on transportation infrastructure affects the climate. Only in a handful of states do transportation agencies even consider how their very expensive highway projects lead to more greenhouse gas emissions.
