Not only do polluters have lower standards to meet under the Trump administration, they may not really have to meet those standards at all.

A newly formed organization called Allow Independent Road-testing (AIR) wants to make impartial emissions ratings available to vehicle shoppers. Using a simple rating from A (best) to H (worst), they would tell you, at a quick glance, how much you’re endangering the health of your family with tailpipe pollutants. Although the idea may seem...

A new investigative report by the New York Times has revealed the puppeteer pulling the strings in the Trump administration's efforts to undo fuel-economy and emissions improvements: no surprise, the oil industry. Backed by America's largest refiners and organizations tied to or funded by the Koch brothers, an underground network coordinated a... 
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... 
The EPA is planning to cancel the special waiver that California has relied on since 1970 to set its own emissions standards, according to a Bloomberg report. As part of its plan to reverse a program to steadily tighten fuel economy standards that it coordinates with California and the National Highway Traffic Safety Administration, the EPA has... 
With automotive emissions regulations again coming under political pressure, we thought we'd re run this Earth Day question from 2014 in an attempt to answer the question: Why all the fuss? Why do we still focus on green cars some 40 years after the EPA imposed the most significant emissions limits on cars? We hope it will provoke thought engender... 
The first major emission controls on motor vehicles were introduced in 1975 with the advent of the catalytic converter. Today's cars emit less than 1 percent of the three "criteria" pollutants that came out of their tailpipes half a century ago. They emit relatively so little carbon monoxide, nitrogen oxides, and hydrocarbons that the collective...
