The EPA has loosened or eliminated a lot of regulations since President Trump took office, but last week the agency announced it would tighten regulations on emissions of nitrogen oxides from heavy trucks such as semis. The EPA notes that smog-forming NOx emissions from heavy trucks fell 40 percent between 2007 and 2017 after the agency last... EPA announces tighter smog regulations on heavy trucks

Last Friday, California released a 400-page repudiation of the Trump administration's plan to freeze fuel economy standards and revoke California's statutory right to set its own limits on vehicle emissions. The report comes in response to the EPA and NHTSA's proposed Safer Affordable Fuel Efficient Vehicles Rule, which would undo fuel-economy... 
Honda joined General Motors on Friday and called on the EPA to abandon its proposed fuel-economy rollback, asking federal officials to negotiate with states like California to offer a single, comprehensive update to federal fuel-economy standards. Honda filed its comment Friday, the last day for public comments, on the Trump administration's plan... 
The term “hail Mary” might be appropriate for what General Motors, led by chief executive officer Mary Barra, is attempting at this stage of the federal government’s dialog on fuel efficiency and electric vehicles. GM is launching an effort to propose a 50-state solution for electric vehicles, including a national version of... 
The EPA has dismissed two panels of outside scientists that advised the agency on particulate matter and ground-level ozone, which have been linked to smog and respiratory problems. Under acting administrator Andrew Wheeler, a former coal-industry lobbyist, analyzing those pollutants will be left to the EPA's internal Clean Air Scientific Advisory... 
A new shorter-range Tesla Model 3 drops into the mix—but not the $35,000 model that many deposit-holders have been waiting for.

Tesla released a... 
Electric cars keep getting cleaner, despite efforts by the EPA and NHTSA to roll back pollution standards on cars and powerplants.

At its meeting on Friday, the California Air Resources Board officially confirmed that it will stick with planned increases in emissions and fuel economy standards for cars sold in the state.

Following news that the EPA dropped plans to keep boosting fuel-economy standards, it quietly dropped another bombshell: It's now fine to guzzle gas. Burn as much as you want. According to an AP report carried by the Detroit News, the Energy Department quietly released the news online in a memo in July in support of freezing fuel economy... 
Smaller, lighter cars always get the blame when politicians want to lower fuel-economy standards. They lobby that too many Americans will be driving lighter cars and that that will lead to more deaths on America's roadways. That's exactly the argument that the Trump administration made earlier this month in its proposal to weaken fuel economy...
