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.

Renault, Nissan limit French government interference

Renault and Nissan are taking action to limit the influence that one can exercise over the other's operations. The measures, announced by both automakers after meetings of their respective boards in Paris and Tokyo, aim to keep each other at arm's length. But more than that, they seek to cap the degree of influence which the French government can bring to bear on either automaker. The steps are being taken in response to investment moves by the French state. While the government's investment arm – known as the Agence des Participations de l'Etat (or state participation agency) – previously controlled 15 percent of Renault's shares, it increased its holdings this April to 19.73 percent. The action sparked concerns at Renault that the French government would attempt to dictate operating procedures to both automakers, potentially to favor production in France over other locations. Given that Renault holds a 43-percent stake in Nissan, the Japanese automaker grew concerned over potential French state interference as well. To assuage those concerns, Renault, Nissan, and the French government came to an agreement with three vital clauses. Most importantly, despite its nearly 20-percent holdings, the French government will be granted only 17.9 percent of voting rights in Renault (to be extended up to 20 percent under certain exceptional circumstances). Renault (and by extension the French government) will also be prevented from interfering in Nissan's governance. With those measures in place, Nissan will not seek more voting rights based on the 15-percent stake which it, in turn, holds in Renault. Having successfully concluded the deal and hedged against the threat of government interference, the Renault board reasserted its confidence in Carlos Ghosn. Through the unique terms of their alliance, Ghosn serves as chairman and CEO of both Renault and Nissan. The two cooperate closely and share resources extending far beyond their chief executive, but remain distinct companies rather than merge, as Fiat and Chrysler have. Renault Board approves alliance stability covenant between Renault and Nissan As early as 16th April 2015, the Renault Board of Directors unanimously reiterated that the sustainability, success and resilience of the Alliance since its very inception in 1999 were based on a balance of shares held by Renault and Nissan.

Ghosn predicts autonomous cars on the roads by 2018, if laws allow

Things appear to be going well inside Nissan's autonomous vehicle development program. Until now, the automaker believed that self-driving cars would be ready for major markets like the US by 2020. However, Renault-Nissan CEO Carlos Ghosn is now speeding up that prediction to 2018 in some places, assuming that local laws are ready to accept the computer-controlled vehicles.
"The problem isn't technology, it's legislation, and the whole question of responsibility that goes with these cars moving around," said Ghosn in a speech in France recorded by Reuters. He predicted that the first sales could begin in France, Japan and the US by 2018 and expand elsewhere in 2020.
The alliance has been among the forefront of automakers working on self-driving cars. Nissan has an autonomous Leaf (pictured above) test car that is licensed to drive on Japanese roads. Renault showed off an version of its Zoe EV earlier this year called the Next Two, that could pilot itself at speeds up to 18 miles per hour, and that the company predicted would be ready by 2020.
