    Carlos Ghosn, the man behind the Nissan Leaf electric car and now the chairman of the Renault Nissan Alliance, isn't the first to say it. But his recent comment that cities are driving the push for electric cars is an important one, because it indicates a prime market for their advantages. The result is that city governments all over the world are starting to push aggressively for more plug-in vehicles—and tackle the impediments to deploying them.

    Could California climate-change rules raise gas price enough to backfire?

    California has by far the most aggressive climate-change policies in the nation, and the state is a global leader in plans to reduce carbon-dioxide emissions. It's also the world's eighth-largest economy, with a growing population, soaring economic output, and a resolutely progressive legislature...

    Real-world diesel emission study shows latest standards must be applied to heavy trucks

    When a major lobbying group issues a statement replying to an academic study the same day that study first hits the media, you know it's major. On Monday, the Diesel Technology Forum responded to an article in Nature with a statement that supported "improved real-world testing" of diesel emissions...

    EPA's Ann Arbor test lab threatened; emission tests in the balance

    The 436 scientists who spend their days testing new vehicles and enforcing environmental rules at the National Fuel Emissions Lab in Ann Arbor, Michigan, face a very uncertain future. The lab sits in the crosshairs of President Trump's proposed budget, which eliminates 99 percent of its funding, as...

  • Golden Gate Bridge, connecting San Francisco and Marin County, California

    California began regulating vehicle emissions within its boundaries before the Environmental Protection Agency was even a gleam in President Richard Nixon's eye. Since that agency was founded in 1971 with an executive order by Nixon, the state has retained the right to set its own—more stringent—emission rules. Now, under President Donald Trump and climate-science denier Scott Pruitt, who runs the EPA, there's widespread fear that the agency will attack the "waiver" it granted to California that permits its zero-emission vehicle sales requirements.

    Ruling that EPA must regulate carbon emissions: now 10 years old

    Extra fuel used if 2022-2025 CAFE rules delayed would be low: here's the math

    Barbie never said "Math is hard!" The talking doll did, notoriously, say "Math class is tough!" in 1989, sparking a media firestorm over gender roles in childrens' toys and then a voluntary recall by Mattel for offended parents. Reworded, however, the point remains accurate: many people don't...

    Newest, cleanest diesels in Europe can still be very dirty: analysis

  • EPA administrator Scott Pruitt  [photo from 2014]

    The current EPA administrator, Scott Pruitt, does not accept the scientific consensus on human contribution to climate change, though he has given some contradictory statements on that matter. His views correspond closely to those of his boss, President Donald Trump, who notoriously compared the science to bovine excrement in a tweet and called climate change a hoax created by China to hurt the U.S. But even Pruitt, it seems, does not plan to challenge a key agency finding on climate science.

    As the Trump Administration nears its 100th day, it seems fair to say that it is still emitting mixed messages on multiple issues, from foreign policy to climate change.

    Despite efforts by Chevrolet to step into the void left by Volkswagen, sales of diesel passenger vehicles in the U.S. may have been permanently crippled by the VW diesel emission scandal.

    Despite some alarmist reporting, President Donald Trump hasn't abolished the EPA's vehicle emission limits. Nor has he wiped out corporate average fuel-economy rules, set by the NHTSA. So far, he's done two things: signed an executive order reopening the comment period for 2022-2025 EPA emission limits, and proposed a budget that would slash EPA funds for actual enforcement.
