"Nearly everywhere you turn during this frigid stretch of winter, much of the world seems covered in a layer of salt aimed at keeping our roads drivable and sidewalks free of ice. All that salt is one reason — although not the only one — that many of the nation’s rivers and streams are becoming saltier, according to new research published Monday in the Proceedings of the National Academy of Sciences."

"OSLO - Sales of electric and hybrid cars exceeded half of new registrations in Norway in 2017, a record aided by generous subsidies that extended the Nordic nation’s lead in a shift from fossil-fuel engines, data showed on Wednesday."

"Some of the most common avatars of climate change – hulking power stations and billowing smokestacks – may need a slight update. For the first time in more than 40 years, the largest source of greenhouse gas pollution in the US isn’t electricity production but transport – cars, trucks, planes, trains and shipping."

"Replacing fleets of medium- and heavy-duty trucks can help cut greenhouse gas emissions and make cities quieter and cleaner."

"Even as President Trump and Republicans in Congress seek to cut federal taxes, the White House has quietly come up with a very different plan for infrastructure: It wants to reward states and localities willing to raise taxes or other revenue to pay for new projects."

"The Trump administration is rolling back a requirement for trains carrying highly explosive liquids — like the oil trains that run through the Columbia River Gorge en route to Northwest refineries."

"A top Volkswagen official in the United States was sentenced on Wednesday to seven years in prison for his role in the German automaker’s decade-long scheme to cheat on diesel emissions tests."

"Elon Musk has always dreamed big, and tonight he showed off his biggest reverie yet: the fully electric Tesla Semi. Powered by a massive battery and capable of hauling 80,000 pounds, it can ramble 500 miles between charges. It’ll even drive itself—on the highway, at least."

"The Environmental Protection Agency proposed a rule Thursday to repeal tighter emissions standards for heavy-duty trucks with older engines, an Obama-era regulation aimed at controlling soot and other pollutants along with greenhouse-gas emissions linked to climate change."

"House Republicans proposed eliminating a $7,500 electric vehicle tax credit that automakers have depended on to prop up early sales."
