Here’s the per person trend for your selected area. Per capita emissions have also ticked up in most metro areas in recent years. The New York Times identified the 100 metropolitan areas with the highest total emissions from driving, based on Boston University’s local estimates: Gately said.īut, he added, “even in the densest cities, the vast majority of trips still happen in a motor vehicle.” These trips include work commutes, school drop-offs and millions of other daily errands, as well as freight deliveries and other business traffic, all of which contribute to planetary warming. Suburban driving, including commuting, has been a major contributor to the expanding carbon footprint of urban areas, Dr. The Trump administration is expected to finalize a rollback of efficiency standards for passenger vehicles this month, a move that could significantly increase future emissions from America’s cars and trucks.Įmissions From Driving Have Grown Fastest in America’s Cities and Suburbsīoston University’s emissions database, first published in 2015 and updated this month with an additional five years of data, reveals that much of the increase in driving-related CO 2 has occurred in and around cities.
But even as vehicles have become more efficient, Americans, buoyed by a strong economy and low gas prices, have been driving more miles and buying more S.U.V.s and pickup trucks, which have lower gas mileage.
National fuel economy standards put in place under the Obama administration have helped temper the rise in automotive emissions because the rules require cars and trucks to use less gasoline per mile traveled. Emissions dipped during the recession of the late 2000s, but have been ticking back up since 2013. Reducing emissions from driving has been a big challenge, said Conor Gately, who led the project mapping CO 2 on America’s roads as a postdoctoral researcher at Boston University. Charts show the carbon dioxide equivalent of greenhouse gas emissions.
