Throughout the world, the accepted science of climate change is no longer in dispute. Every nation on earth has now signed the Paris Climate Treaty to develop plans to reduce the carbon emissions that contribute to global warming. Only one plans to withdraw from that treaty: the United States of America. DON'T MISS: All renewable energy types to... 
With the release of proposed new and lower fuel-economy rules expected from the NHTSA by March 30, many eyes have turned to the powerful California Air Resources Board. The state's pioneering role in reducing emissions and cutting air pollution predates even the existence of the U.S. Environmental Protection Agency. That agency, now run by Scott... 
Today, there are roughly 750,000 plug-in electric vehicles on U.S. roads and about 3,800 powered by hydrogen fuel cells. Proponents of each type of vehicle argue strenuously that their powertrain is a better way to produce vehicles with zero emissions from the tailpipe. Electric cars can be charged at home overnight, and electricity in many areas... 
While VW is moving toward the end of buybacks, payments, and fines for eight years of cheating on diesel emission standards, Fiat Chrysler is still in the thick of its own diesel mess involving Jeep SUVs and Ram trucks. On February 2, the U.S. Justice Department offered to let the company move forward if it recalls all 104,000 EcoDiesel models of... 
The subject of carbon dioxide emissions is hardly a simple one, especially when it comes to electric cars. They may not have tailpipes, but the electricity generated in order to keep them going has to come from somewhere. Electric utilities, it turns out, are doing their bit to reduce carbon emissions—and that makes it even more important... 
You may recall that President Donald Trump made some ambitious and audacious campaign promises about his plans to revive America's dwindling coal industry. Two weeks ago, The Washington Post fact-checked the president's delivery on those promises after his first year in office—in multiples of "Pinocchios," its measure of untruthfulness for... 
Last month, U.S. Energy Secretary Rick Perry signed an agreement with Saudi Arabian officials to research "carbon capture" technology for fossil fuels, the Department of Energy announced. Perry and Khalid Al Falih, the Saudi Minister of Energy, Industry, and Mineral Resources, signed a memorandum of understanding to "establish a framework for... 
As automakers await the National Highway Traffic Safety Administration's new fuel-economy rules for 2022 through 2025, due March 30, regulators from California and Washington are still hammering out the specifics. A meeting between state and federal regulators on fuel-economy and emissions targets took place on Monday as both sides attempt to... 
As nations, automakers, and utilities contemplate how to tackle climate change in real terms, a perfect storm of competition is brewing that will—ideally—produce positive change for the rest of us. Automakers and electric utilities have been incentivized to build electric vehicles and install vast numbers of public charging stations to... 
One year ago at the Detroit auto show, a company called Achates Power unveiled models of a new kind of internal-combustion engine. With opposed pistons in the middle and crankshafts at either end, it was sufficiently different to startle most visitors who paid attention. That engine came with some audacious claims, too: How about an EPA combined... 
One of California's largest electricity producers recently published a white paper that analyzed how the state will achieve its 2030 greenhouse-gas targets—and it called into question targets set forth by California regulators. Specifically, Southern California Edison (SCE) said the targeted 4 million electric vehicles isn't nearly enough to... 
It's been hanging out there in limbo for more than six months: the answer to the question of what happens to gas-mileage rules under Trump. Given the daily political turmoil emanating from Washington, D.C., the fate of corporate average fuel economy rules may have gotten lost in the noise. But for automakers and consumers, the fate of current CAFE... ![First all-electric articulated bus in the world, Palmdale, CA, by Nate Pitkin [CC BY-SA 4.0]](https://images.hgmsites.net/tmb/first-all-electric-articulated-bus-in-the-world-palmdale-ca-by-nate-pitkin-cc-by-sa-4-0_100638880_t.gif)
California is using the growing sums of money it receives from its emission cap-and-trade auction for good, including to tackle up some of the state's most egregious transportation polluters. In mid-December, California announced it would invest $663 million in a plan to clean up particularly dirty fleets, especially those operating in low-income... ![Electric-car rally in Geiranger, Norway [Image: Norsk elbilforening via Flickr]](https://images.hgmsites.net/tmb/electric-car-rally-in-geiranger-norway-image-norsk-elbilforening-via-flickr_100530088_t.gif)
Norway was one of the earliest nations to set a coherent and broad-based national plan to cut its carbon emissions, and then stick to it. For road transport, it plans to phase out sales of cars with internal-combustion engines by 2025 using a variety of carrots (financial incentives and special privileges) and sticks (very high taxes on... 
As children, we're all taught to turn off the lights behind us as we leave an empty room. But it seems Norwegians have taken that lesson one step further. Along a 5.5-mile stretch of road in Hole, Norway, smart streetlights automatically dim when nobody's around—then come back to full power when a car, pedestrian, or other object approaches... 
In discussions of climate change, much of the focus has been on the combustion of fossil fuels: coal, oil and its gasoline and diesel-fuel derivatives, and natural gas. Collectively, the trillions of tons of carbon dioxide emitted into the atmosphere by man since the start of the industrial revolution around 1750 have contributed to a massive rise... 
China has taken a major step toward cleaning up the new cars sold in the country beginning January 1. As numerous countries debate plans to end sales of fossil-fuel vehicles completely at points in the future, China has now forced the end of production for some 553 models, starting Monday. The vehicles, from a wide range of automakers, can no...
