This map reveals the cleanest vehicles based on location

Naysayers love to point out how dirty the electricity grid mix is when it comes to charging electric vehicles. Curmudgeons are eager to jump into any conversation about EVs to enlighten the lucky listeners about how plug-in cars contribute to pollution, sometimes even throwing in a dash of climate-change denial for good measure. (Thanks, buddy. Pray, tell me more about the plight of oppressed SUV owners.) Unless someone buys an EV just because they think they're cool (which, yeah, they often are), they probably have at least a passable understanding of their environmental pros and cons. As many EV owners are already aware, location has a lot to do with any particular plug-in car's carbon footprint. Still, there's always more to know, and knowledge is not a bad thing, especially if one uses it to do the right thing. That's why this handy-dandy map from Carnegie Mellon University is so interesting. CMU researchers have compiled information about the lifecycle greenhouse gas emissions of various EVs based on where they're charged, as compared to gasoline-powered vehicles. The researchers looked at the Nissan Leaf, Chevrolet Volt, and Prius Plug-In Hybrid versus the gasoline-dependent Toyota Prius hybrid and the stop-start-equipped Mazda3 with i-ELOOP and compared grams of CO2 emitted per mile. CMU takes into account the grid mix, ambient temperature, and driving patterns. CMU takes into account the grid mix based on county, as well as ambient temperature and driving patterns in terms of miles traveled on the highway or in the city. For instance, if you drive a Nissan Leaf in urban areas of California, Texas, or Florida, your carbon footprint is lower than it would be if you were driving a standard Toyota Prius. However, if you charge your Leaf in the Midwest or the South, for the most part, you've got a larger carbon footprint than the Prius. If you live in the rural Midwest, you'd probably even be better off driving a Mazda3. Throughout the country, the Chevrolet Volt has a larger carbon footprint than the Toyota Prius, but a smaller one than the Mazda3 in a lot of urban counties in the US. The Prius and Prius Plug-In are relatively equal across the US. Having trouble keeping it straight? That's not surprising. The comparisons between plug-in and gasoline vehicles are much more nuanced than the loudest voices usually let on.

Nissan Leaf EVs slip through French village to make a quiet point

Bjork's 1995 freak-out hit It's Oh So Quiet may have reflected the singer's oddball Icelandic sensibilities, but Nissan is making the concept of relative silence a French thing. The Japanese automaker recently promoted its all-electric Leaf by staging a mini-rally through what it called "one of the quietest villages in Europe." And with the exception of a couple damaged trash bins and a destroyed rear-view mirror from an old-school archway, the race kept the drivers wide awake but everyone in the Southern French village in Provence Alpes Cote d'Azur sleeping. Nissan sent four vehicles on a five-kilometer jaunt through the village in the wee morning hours. Screeching tires and a couple booms notwithstanding, the company said everyone in town stayed snoozing. There was a broader purpose to this exercise, of course, which Nissan blatantly admits was a stunt. Nissan was helping celebrate 19th Annual International Noise Awareness Day (INAD), which took place on Wednesday and highlighted the emotional and health issues as well as high blood pressure and insomnia caused by excessive exposure to noise.

NISSAN LEAF CELEBRATES INTERNATIONAL NOISE AWARENESS DAY WITH A NIGHTTIME "SILENT RIDE" ROLLE, Switzerland – To mark the 19th annual International Noise Awareness Day (INAD), Nissan has taken to the streets of one of Europe's quietest villages during the middle of the night with a silent "ride" of its 100 percent electric Nissan LEAF. The activity, complete with a start and finish line in Provence Alpes Cote d'Azur, was designed to demonstrate the noise reduction levels of the Zero Emissions car compared to traditional combustion engines. The World Health Organization (WHO) states at least 13.5 percent of Europeans are exposed to road traffic noise at levels exceeding 55 dB, which is considered detrimental to human health*. The medical effects of noise levels include insomnia (50dB), obesity (50dB), psychic disorders (60dB) and reduction in life expectancy (50dB)*. As a result, Nissan has filmed a 'silent ride' to help support INAD in raising awareness about noise pollution levels across Europe.

Nissan presents NV200 is the brave new face of London taxis [w/video]

In most cities, just about any vehicle can serve as a taxi - so long as it meets the owner/operator's requirements for reliability, comfort and utility. But certain cities have their own unique taxis, and Nissan has been working hard to corner those markets. It has already designed specific taxis for such locations as New York, Barcelona and Tokyo, but its latest effort will bring a new Hackney Carriage to the streets of London.
A year and a half ago, Nissan displayed its NV200 on the streets of London in traditional black livery. But this new design takes the customization for the British capital one step further. Working closely with the mayor's office and with cab drivers across the city, Nissan's European design center in the Paddington district has reskinned the NV200 specifically to serve as the new black cab in London. The new face features round headlights, a new grille, LED lighting and a restyled front bumper. The steering has also been reconfigured to meet the 25-foot turning circle requirements for Hackney Carriages, as the black cabs are known on the streets of London.
The result is a distinctly British take on the NV200 taxi - one that we're guessing won't go without its fair share of controversy. Nissan will begin offering the black cab at the end of the year with a 1.6-liter gasoline engine mated to an automatic transmission, a powertrain said to be cleaner than the diesels used in existing taxis. And Nissan should know, having supplied many of those 2.7-liter turbodiesels in the '80s and '90s. But if that's not clean enough, the Japanese automaker will also begin selling an electric version, the e-NV200, starting next year.
