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's Twizy-like New Mobility Concept EV adds modern charm to old town in Japan

While alliance partner Renault gets to give its quirky, side-window free electric vehicle a fun name like Twizy, Nissan has opted for the much-less-interesting New Mobility Concept. To company is promoting the vehicle with a similar, let's-not-get-too-excited-here vibe, saying that it's "perfect even for mom" (not that mom's aren't exciting) and limiting it to carsharing and test program users. In the latest promotion effort, Nissan has brought the NMC to the tourist town of Shikano, in the east of Tottori Prefecture, to be used to get to hot spring excursions and other visits. Renting the vehicle costs roughly the equivalent of $10 an hour ($40 for six) as well as $12 to get a training license. You can see the little car in action in the video above, including some entirely interesting shots of the NMC painted like a cow with a pair of cows.

Carlos Ghosn video: 'This is about conspiracy. This is about backstabbing'

TOKYO — Nissan's former Chairman Carlos Ghosn maintained his innocence in a video released by his legal team Tuesday and accused some executives at the Japanese automaker of a "conspiracy" that led to his arrest on financial misconduct allegations. "The first message is that I'm innocent," said Ghosn, wearing a white shirt and dark jacket and speaking calmly in the nearly 10-minute video shown at the Foreign Correspondents' Club in Tokyo. "This is a conspiracy," he said. "This is not about specific events, this is not about, again, greed, this is not about dictatorship. This is about a plot. This is about conspiracy. This is about backstabbing." His lawyer Junichiro Hironaka said the video was prepared in case Ghosn was not able to speak at a news conference planned for Thursday. Ghosn was arrested last week while out on bail and remains at the Tokyo Detention Center. Ghosn said the executives behind the conspiracy were motivated by what he called "selfish fears," including what they saw as a merger with French alliance partner Renault SA. They mistook his leadership for greed and dictatorship, when he was the biggest defender of Nissan's autonomy, Ghosn said. He also said he was worried about Nissan, wondering whether those executives were really watching out for the company. Hironaka said a section of the video in which Ghosn mentioned names was removed on his legal advice. Nissan Motor Co., while declining to comment on the criminal case, has said an internal investigation has found that Ghosn falsified financial documents to under-report compensation, and that he used Nissan money for personal gain. "Nissan's internal investigation has uncovered substantial evidence of blatantly unethical conduct," company spokesman Nicholas Maxfield said when asked for comment on Ghosn's video. "The company's focus remains on addressing weaknesses in governance that enabled this misconduct." Ghosn's fourth arrest was on a fresh breach of trust allegation based on suspicion that payments from a Nissan subsidiary to an Oman dealership were diverted to a company effectively run by Ghosn. On Monday, Nissan Motor Co. shareholders voted to oust Ghosn from its board and to approve the appointment of French alliance partner Renault SA's Chairman Jean-Dominique Senard as Ghosn's replacement. Renault owns 43 percent of Nissan.
