emissions

Journalism as an industry is under great pressure these days. There are far more people writing "content" than in past decades, and in general they are having to produce more of it for less money than they did 10, 20, or 50 years ago. That's no excuse, however, for getting the basics wrong. DON'T...

Norway and The Netherlands started the trend a few years ago, though they're relatively tiny car markets. Then France and the U.K. joined in. China, the world's largest new-car market by far, is doing it—though the country hasn't decided when. All of those countries plan to ban, or work the...

Despite the sturm und drang around the announcement by embattled EPA chief Scott Pruitt that he will relax emission limits for 2022 through 2025 vehicles, not much will happen immediately. His determination last week that the Obama administration was "incorrect" and that the limits on those...

New York Magazine article draws dire conclusion that catastrophic climate change is nearly inevitable, with or without Paris climate accord.

While the name of EPA administrator Scott Pruitt is often preceded by "embattled" these days, his agency is now on record as rejecting its own recommendation of just 16 months ago. It concluded in July 2016 that the auto industry had handily met lower carbon-emission limits from 2012 through...

EPA administrator Scott Pruitt said yesterday the agency plans to modify rules limiting carbon-dioxide emissions for light-duty vehicles in model years 2022 through 2025. The agency, he said, had reached a determination that the limits put in place in 2012 under the Obama administration were...

EPA administrator Scott Pruitt would be controversial even if he hadn't flown to Morocco in December (first-class, on the taxpayer dime) to lobby the country on the benefits of liquified natural gas while living in a condo owned by a lobbyist for the country's largest LNG exporter. He is likely the...

The omens have been accumulating for months, as bits of information dribble out of the regulatory rumor mill in Washington, D.C. Now we have the most concrete reports yet that the U.S. EPA plans to modify exhaust emission limits for vehicles in model years 2022 through 2025. The EPA delivered its...

Last Tuesday, EPA administrator Scott Pruitt said the agency does not intend to let California set the agenda for national emission limits on vehicles. He suggested to Bloomberg the EPA plans to cut emission rules aggressively to respond to carmakers' pleas for easing of the corporate average fuel...

Well, that's awkward. At its annual media briefing on Wednesday, Volkswagen Group executives said the costs of meeting new emission tests in the EU, lowering carbon emissions globally, and launching multiple new electric models would eat into the company's profits. With the company's diesels in...

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...

It might be the world’s largest single-company junkyard and pick-a-part business, if not for the prominent "No Trespassing" and "Drone-Free Zone" signs. Instead, it’s a massive storage facility in Colorado for thousands of disgraced VW and Audi TDI diesel vehicles awaiting whatever fate...

More good news about electric cars in the U.S.: the emissions associated with the electricity used to charge them have fallen. Again. Based on the latest data on powerplant emissions from the EPA, an electric car on the road in the U.S. now has average emissions as low as an 80-mpg car. DON'T MISS...

First Paris, then a pair of German cities, and now the Eternal City. Two weeks ago, the mayor of Rome announced on her Facebook page that the city would ban diesel cars altogether by 2024. It's not clear whether the ban applies solely to the older, most-polluting diesels as it does already in...

The most recent detailed studies on the likely warming of Planet Earth are grim indeed, suggesting that we are collectively at "very high risk" for the most extreme effects of climate change. To stem that, mankind collectively will have to reduce its ongoing emissions of carbon dioxide radically...

That huge intake of breath you may have heard from across the Atlantic Ocean was the sound of German carmakers gasping at a court decision handed down on Tuesday. After a week's delay in issuing its ruling, a German court decided that individual cities in the country may ban vehicles with diesel...

Last November, the Environmental Protection Agency said it would rescind a rule that banned companies from fitting outdated, older, and dirtier diesel engines into brand-new "glider" chassis-cab trucks. Among the many regulations to limit emissions and other forms of pollution that EPA...

Fiat Chrysler will abandon the use of diesel engines in all its passenger vehicles by 2022, according to a report Sunday. Demand for diesel versions of passenger cars in Europe is waning and car makers face extraordinarily high costs to get diesel engines to comply with emission limits in...

Investigators probing U.S. models of Mercedes-Benz sold with diesel engines have found software, possibly illegal under EPA rules, that helped them pass emission tests. Such software may be similar to that notoriously used in 580,000 vehicles sold by VW, Audi, and Porsche from 2009 through 2015 in...

The processes of climate change don't care about politics. Or economics. Or public sentiment about science. Last December, an analysis showed the most accurate climate-science models to date predicted the worst effects in future years. Now, two more grim assessments have arrived. DON'T MISS...
