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 senators have stepped forward with an official... CA legislators propose $1 billion to remove dirtiest diesel trucks
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 senators have stepped forward with an official... 
Efforts to loosen regulations on the oil industry now underway have met with public approval from fossil-fuel companies. But while the Trump administration has moved swiftly to create a more friendly regulatory environment for big oil, some executives have urged a slowdown behind the scenes. That's not for environmental reasons, but due to worries... 
Sometimes, when science and technology issues have economic or political consequences, incorrect or misleading information and analyses can be propagated through the media, leading both decision makers and the public astray. A piece published in April by Forbes, covering the effects of the 2022 through 2025 corporate average fuel economy... 
The warning came even before last week's plans for updates to 9 million European diesel cars by German luxury makers Audi and Mercedes-Benz were announced. In a letter sent to the transport ministers of European Union countries, EU industry commissioner Elzbieta Bienkowska warned that proposed bans on diesel cars in European cities could backfire... 
The U.S. Department of Transportation said yesterday the NHTSA is preparing to revise corporate average fuel economy requirements for model years 2022 through 2025. The proposed version of those regulations, which was issued by the Obama Administration in 2012, included steady increases for each of those model years. Among the alternatives that... 
The United States House of Representatives has taken the first step towards allowing automakers and technology companies to deploy self-driving cars on public roads. A House panel passed a proposal that would allow automakers and other companies to deploy up to 100,000 self-driving vehicles. Significantly, the bill does not require the... 
It may be human nature to avoid doing things that are for the long-term good but impose short-term costs. Exercising more, giving up smoking, or paying more for a car that is better for the environment all challenge many otherwise responsible citizens. And it's abundantly clear that the emergence and sales of electric cars benefit greatly from... 
Drivers in the U.S. have longer commutes than those in Europe and Asia, on average. In the U.K., short commutes in vehicles with combustion engines—whether gasoline or diesel—pose particularly tough emission problems. That's because the exhaust aftertreatment systems have to warm up fully before they cut emissions to the levels... 
A global push to reduce vehicle emissions and create cleaner air for future generations has been underway for half a century now. However, while many governments around the world have introduced lower emission and higher fuel-efficiency standards for passenger cars, another large contributor to global emissions has mostly traveled under the radar... 
The U.S. is coming up to its Independence Day holiday, in which we celebrate the Declaration of Independence from England and reflect on our history and traditions as a nation. This is an interesting time to do that, and there's a cynical argument to be made that backroom politics is as American as apple pie and bald eagles. Which brings us to the... 
Modern electric cars have been on U.S. roads for seven years or so, and owners love their smooth, quiet, close to noise-free operation. That silence has been a bone of contention for even longer, however, since hybrids operating purely on battery power are similarly quiet. For years, the U.S. Department of Transportation was charged with drafting... 
Volkswagen is following the lead of many other global automakers: it has signed a deal for a new electric-vehicle joint venture in China. The German automaker said this week it has partnered with Chinese automaker Anhui Jianghuai Automobile Co. (JAC) to produce electric vehicles, as well as to market various mobility services. Both Volkswagen and... 
What's a truck? If you tell your average suburban family that they're hauling their kids to school and sports practices in a truck, many will push back. "It's an SUV," you'll likely hear, or perhaps, "it's called a crossover"—short for crossover utility vehicle, or a car-based SUV. DON'T MISS: Are you driving a car, a crossover, an SUV, or a... 
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... ![Smog obscures George Washington Bridge, 1973 [From EPA Documerica series]](http://images.hgmsites.net/tmb/smog-obscures-george-washington-bridge-1973-from-epa-documerica-series_100594067_t.gif)
Much of the news out of Washington, D.C., these days has to do with the possibility of political scandal. But the wheels of government keep turning, and significant changes are happening at numerous agencies charged with missions as diverse as collecting intelligence, supporting education, and protecting the environment. Few groups are seeing... ![Natural gas flaring from oil well [licensed under Creative Commons from Flickr user Sirdle]](http://images.hgmsites.net/tmb/natural-gas-being-flared-from-oil-well-licensed-under-creative-commons-from-flickr-user-sirdle_100443858_t.gif)
While much of the nation's capital is preoccupied with the unpredictable Trump administration and its possible ties to Russia, the fate of the Environmental Protection Agency generates less news coverage. That's not to say there hasn't been news. Administrator Scott Pruitt is proceeding swiftly with a radical plan to restructure—critics... 
It was one of several common tropes used 10 years ago against proposed regulations to boost average fuel economy. "More efficient cars will have to be lighter-weight, and they'll be unsafe because in accidents, they'll crumple up like Kleenex." Logical conclusion: if you require higher fuel economy in cars, more people will die in crashes. DON'T...
