Donald Trump's White House appears to be readying another of its next big climate change overhauls, and like many of the administration's plans, it will weaken or eliminate regulations on industry. Specifically, President Trump touted the undoing of the Clean Power Plan at a rally in Huntsville...

You may not have heard it happen, but the global automotive industry changed forever on Thursday. China released its plan to require substantial sales of plug-in electric cars by all makers who want to sell in the world's largest car market, and they start in little more than a year. The levels far...

The prospect of bans on gasoline and diesel new-car sales have become a much greater threat not only to automakers but to oil companies as well, now that China has said it is studying such a move. The world's largest car market has not announced any timetables for such a ban, which will likely be...

It was quaint and adorable when Norway did it, saying it would end sales of cars with internal-combustion engines by 2025. The Netherlands followed suit, with little fanfare. More recently, France and the U.K. have enacted various forms of bans on non-electrified vehicles, on varying schedules. Now...

For 50 years, the state of California has led the United States when it comes to renewable energy and electric cars. The state features many programs to incentivize electric-car ownership, and 29 percent of the state's 2016 energy production came from solar, wind, and other renewable power sources...

Mazda is a tiny carmaker on a global scale, producing just 1.6 million vehicles a year. It competes with four companies (GM, Nissan-Renault, Toyota, and VW Group) that each sell around 10 million a year, as well as numerous other smaller makers still larger than Mazda. In a world where reducing the...

China made headlines around the world on Sunday when state media reported that the country is developing a timetable to end production and sales of new vehicles with gasoline engines. While Norway, The Netherlands, France, and the U.K. have adopted different timetables for various versions of such...

Lately, automakers haven't been touting the rising fuel economy of new vehicles, but it has to continue rising to meet reductions in the legal levels of carbon emitted. While major strides in fuel economy have been made over the past five years, the complex engine technologies and other...

Hurricane Harvey will go down as one of the most destructive and costliest natural disasters in the United States. While the storm has dissipated, with this week's attention focused on Hurricane Irma, the effects and damage tolls will last for years—and one thing already seems clear: Texas'...

Although electric cars do not emit exhaust, it's widely recognized that the electricity to charge their batteries often still comes from fossil fuels. This has led to the scrutiny of electric cars to determine whether their overall "wells-to-wheels" carbon footprints exceed those of regular...

Updated Volkswagen diesel vehicles with new engine software will soon be back on the market, but those looking to buy one will have to wait for their local dealership. Volkswagen will offer the hundreds of thousands of modified diesel vehicles to its franchised dealers first, offering them a "right...

Uber has announced it will require its 40,000 drivers in London to switch to hybrid or fully electric cars, and ban diesel vehicles from its fleet, by the end of 2019. By the end of 2021, it will extend that policy throughout the United Kingdom, where it presently operates in 40 cities. Uber said...

Most analysts agree the future of the automobile will slowly but increasingly come to rely on battery power. Electric cars will slowly displace internal combustion engines, many researchers suggest, and peak demand for fossil fuels used in transportation could arrive as soon as the next decade...

The state of California has officially launched its legislative push for stricter heavy-duty truck and bus emission regulations. Following calls for the state to use its recently-extended carbon cap-and-trade program to fund updates to fleets of semi trucks and other commercial vehicles, four state...

Fuel-economy ratings for cars sold in Europe have long been wildly unrealistic, sometimes more than 30 percent more optimistic than real-world consumption figures. Today, that will change. As of September 1, two new and more stringent testing regimes are to be used for certifying new vehicles going...

Sometimes it's best not to dare the public to do the research, especially if you're trying to persuade them of something that isn't true. Almost two years ago, Inside Climate News published a significant expose that confirmed Exxon's own scientists had agreed that human carbon emissions contributed...

Diesel-powered cars, long a staple on European roads, are starting to lose favor as million of dollars of inventory begins to pile up in used diesel models. The inventory, largely recent models certified under the superseded Euro-5 emission standards, has boomed recently over the possibility the...

It has been nearly two years since Volkswagen came clean and admitted its "clean diesel" engines were actually quite dirty. In 2015, a VW engineer admitted the TDI diesel cars sold in the U.S. since 2009 were outfitted with "defeat device" software that let them pass emission tests, only to emit...

Former Volkswagen employee James Liang was sentenced in Detroit on Friday to serve 40 months in prison and pay a $200,000 fine for his role in the global Volkswagen diesel-emission cheating scandal. It was a stiffer sentence than expected for an engineer who helped to create software that...

Just 30 years ago, people could smoke anywhere, including offices, malls, and restaurants. The 1987 opening of a New York City restaurant called "Nosmo King" (read it again) was considered a bizarre, if amusing, idea that restauranteurs said would bankrupt the place because no one would give up...
