Reducing emissions from driving has been a big challenge, said Conor Gately, who led the project mapping CO2 on America's roads as a postdoctoral researcher at Boston University. Emissions dipped during the recession of the late 2000s, but have been ticking back up since 2013.
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. 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. Freight trucking is also on the rise.
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.
First, and most important, this is not a map of pollution. Its a map of CARBON DIOXIDE which is not pollution, it is the stuff humans breath out. Plants -need- carbon dioxide, right? This is another global warming fairy tale filled with dire Greta Thunberg warnings about how your car is going to cause the end of the world.
To create their database, Boston University researchers used federal traffic data to calculate the number of miles travelled on local segments of each road in the United States and converted those miles to carbon dioxide emissions by estimating how much fuel is consumed by different types of vehicles using those roads.
An additional New York Times analysis used Boston University's on-road CO2 data and population figures from the National Institutes of Health and the U.S. Census Bureau to derive total and per capita emissions for each metropolitan area.
They made it up.

This eco crusade is a bit rich coming from a business that mainly turns trees into disposable fake news.
Unfit to wrap fish. Complete waste of perfectly good paper.
