It's no secret that China's auto market has been growing rapidly, surpassing the US market in unit sales for the last two years. While that's an indicator of the country's strong economy, it has also created serious pollution and congestion problems in China's largest cities. During the week of...

Some of the first emissions regulations in the world came about because of the way the Los Angeles Basin is shaped. Reports of smog in southern California started with the Conquistadors, and by the Sixties, LA was notorious for its foul air. California began regulating auto emissions before the...

Why are many European carmakers now planning to build electric vehicles? Because many European cities are widely expected to ban high-emissions vehicles from their city cores over the next decade--perhaps even vehicles with any emissions at all. Now, Paris may be the first city to experiment with...

Well, now we know the numbers. And there are a lot of them. The U.S. Environmental Protection Agency and Department of Transportation jointly proposed cutting greenhouse-gas emissions from medium and heavy duty trucks by 10 to 20 percent, starting in 2014 and extending through 2018. (The actual...

We like it when a study confirms a common-held belief. And for hundreds of would-be electric car owners across the U.S. a recent study has done just that. Years into the Military Conflict in the Middle East, and just months after the Deepwater Horizon Oil Spill a team at Rice University have...

With electricity not always generated through renewable methods, it can be hard to claim that an EV is truly zero-emissions. It's generally accepted that you aren't pumping any gasses out the back as you drive along, though. Well, the car shouldn't be anyway... Despite this, electric vehicle...

It was so much easier just a few short years ago. Luxury cars wafted and sports machines roared, with nary a thought to gasoline consumed. Hybrids were for weenies, and everyone knew their place. But now? A hybrid Ferrari, a hybrid Porsche race car, an electric BMW ... what is the world coming to?...

Not only do old cars pollute more than new ones, they pollute a lot more. According to a rule proposed by the California Bureau of Automotive Repair, fully “75 percent of vehicular pollution is caused by just 25 percent of the vehicle fleet" in the state. Those vehicles were built before 1995...

We are mostly humble peasants here at Green Car Reports. We just try to report on green cars fairly, with an occasional bit of acerbity tossed in for flavor. Once in a while, we post a story that hits a chord, including our discussion of why the 2011 Chevrolet Volt may not get either an EV purchase...

If you've been to New York City lately, you may have noticed an increasing number of hybrid taxis on the roads: mostly Ford Escape Hybrid SUVs, but also Toyota Camry Hybrid and Nissan Altima Hybrid sedans, and a scattering of others too. It's part of a long-term plan to green the fleet of 14,000...

 The EPA and CARB like zero emissions vehicles, but don't want you controlling when you decide your vehicle is zero emissions. According to Tony Posawatz, line director for the Chevy Volt program, the two agencies concerned with protecting the emissions from cars aren't happy about a plug in...

We read a lot of stuff here to cover the world of green cars. No surprise there. But there's a lot we see that doesn't lend itself to a full article, though we hate to let it pass by altogether. So this is a new type of piece, one that brings together stuff that's sort-of-relevant to green cars...

It must be Friday, when the silly stuff comes up. According to Japan Times, in the Kansai region of Japan, four companies have got together to produce a new vehicle which they hope will capture the hearts and minds of eco-minded visitors needing a way to get around the ancient cities of Kyoto and...

Yesterday, we published a piece called Five Myths About Electric Cars, Courtesy of Think, whose CEO Richard Canny sent them to us. Today we have five more, to finish off his list of 10 myths. Below is the second half of Canny's list (which is why it begins with # 6), along with our assessment of...

Last Thursday was the 40th anniversary of Earth Day, and the CEO of one electric-car maker took the occasion to speak out on some of the popular myths around the manufacturing and use of electric vehicles. Richard Canny, who runs the recently refinanced Think, published a list of "top 10 EV myths...

Almost a year ago, we called Bentley's much-touted biofuels strategy "bogus," in an alliterative headline to a piece that was much forwarded around the green-car world. Now we've had a chat with the very reasonable and polite David Reuter, Bentley's head of PR and communications. We still think...

As we keep saying, one of the ways that automakers will meet more stringent fuel economy regulations is by making smaller engines that work harder. Now Fiat has one-upped its European competition by announcing it will offer a 900cc turbocharged twin in European models of its Fiat 500 mini-car. That...

When automakers and the Obama White House announced agreement on a single national standard for emissions and fuel economy last May, the entire auto industry heaved a huge sigh of relief. The issue was settled, at least until 2016. Yesterday, however, the state of Texas filed suit in the U.S. Court...

One problem with raising fuel efficiency is that unless total miles driven rises radically, receipts from gasoline taxes will fall over time. And that poses a major problem for the steady stream of revenue needed for road construction and repairs. Taxing vehicle miles traveled has been one proposed...

The dirty little secrets of Top 10 lists are in the methodology, as Forbes found out with its weirdly inaccurate "10 Dirtiest Cars" list. (It's the end of the year, so it's time for a lot of Top 10s.) But we see no such problems in the EPA Green Vehicle Guide, which rates vehicles not only on...
