As the Trump administration abandons numerous U.S. efforts to rein in emissions of the climate-change gas carbon dioxide over time, another large polluter is pushing ahead with an aggressive plan to slash pollution from energy producers. China, currently the top carbon emitter and largest consumer...

A scrappage scheme in Germany launched by Volkswagen to take the dirtiest diesels off the road has been extended beyond its planned end date of this month. Two years after the diesel emissions scandal that cost it over $25 billion, Volkswagen is extending an incentive program aimed at owners of...

The denial of accepted climate science by the Trump Administration has now put the U.S. at odds with essentially every other nation in the world. Meanwhile, the news on the effects of higher concentrations of carbon dioxide in the atmosphere is, if anything, getting worse. A recent analysis of...

With the exception of California's longstanding ability to set its own tougher emission standards, any car legal to sell in one state of the U.S. is legal to sell in all of them. And aside from a handful of differences—daytime running lights, speedometers marked in km/h—Canadian-market...

As the electric-vehicle market matures and more global automakers commit to building battery-powered cars, one driving force has emerged to lead the pack. With apologies to the title of a comedy from half a century ago ... The Chinese Are Coming. That's the assertion made by old China hand Michael...

In grade school, students commonly ran through the halls when teachers or other school staff weren't looking. Signs forbidding the act of sprinting past lockers did little to deter the practice, since there was no incentive not to run unless someone present was enforcing the rule. The same can be...

One of the interesting side effects of plug-in electric cars turns out to be a greater awareness of energy sources and uses. A 2012 California study, for instance, showed roughly four out of 10 electric-car drivers either had or were considering solar panels to provide electricity to their home...

EPA head Scott Pruitt will likely go down as one of the most controversial agency chiefs in that agency's history of almost 50 years. The former Oklahoma attorney general, who sued the EPA 14 times on behalf of fossil-fuel interests during the Obama administration, has a radically different view of...

For 45 years, the Environmental Protection Agency has been charged with protecting the U.S. from pollution in its air, water, and land. Under the Trump Administration, its administrator Scott Pruitt is aggressively muzzling and removing scientists, eradicating climate-science from its activities...

When top U.S. scientists released the fourth National Climate Assessment, it spelled out one blunt conclusion: human activity in releasing carbon dioxide into the atmosphere caused the climate change that has warmed the globe. Mandated for release every four years, the report will apparently have...

When electric cars first arrived in 2011, it was a reasonable question: Aren't you just shifting emissions from the tailpipe to the smokestack? The answer is yes, but the carbon emissions per mile of an electric car—properly measured on a wells-to-wheels basis—are virtually always lower...

When the Environmental Protection Agency quietly issued its new four-year plan in mid-October, the phrase "climate change" did not appear anywhere in the 38-page document. It is now clear the Trump Administration intends to delay, halt, or erase government efforts to limit U.S. emissions of carbon...

Diesel-powered cars have enjoyed a comfortable market share in Europe for decades, but their decline in popularity continues following numerous diesel-emission cheating scandals and regulatory crackdowns. As if diesel cars hadn't already had enough negative press, a new study says "fuel-efficient"...

Presuming China sticks to its statement that it will ban sales of new vehicles with combustion engines in some future year, the auto industry is facing a very different future than it was a year ago. Similar bans from Norway, The Netherlands, France, and the U.K. all represented smaller markets...

Numerous European countries have rolled out target years in which they plan to ban the sale of new cars powered by internal-combustion engines. At the same time, many European cities have introduced car-free zones in highly congested or polluted areas—which has led to worries that...

European countries continue to assess more aggressive policies that favor or mandate zero-emission vehicles to move away from fossil fuels for transportation. Last year, a recommendation passed by the Dutch senate proposed The Netherlands join Norway in banning the sale of new cars powered solely...

France followed two other European countries—Norway and the Netherlands—with a plan to ban the sale of new cars powered by gasoline and diesel by 2040. While the country will stick to the 2040 timeline, France's capital city of Paris announced a more aggressive timeline. Ten years ahead...

Toyota announced on Thursday that it will begin testing in two California ports a hydrogen fuel-cell heavy-duty truck adapted from the Toyota Mirai's powertrain for drayage use. Initially, Toyota is looking at how it can use hydrogen fuel-cell-powered vehicles to significantly reduce vehicle...

EPA head Scott Pruitt told miners in Kentucky on Monday that he intends to begin dismantling former President Barack Obama's signature climate-change agenda effort to curb greenhouse gas emissions from coal power plants. Standing alongside Senate Majority Leader Mitch McConnell (R-Ky.), Pruitt told...

California, long a leader in emission reduction and electric-car incentives, may be ready to take the next big step: a full ban on the sale of new cars powered by gasoline or diesel. Such a ban would follow India, the United Kingdom, France, the Netherlands, Norway, and others around the world with...
