Cleaner Cars From Cradle to Grave (Union of Concerned Scientists)
"This report compares battery-electric vehicles (BEVs) with similar gasoline vehicles by examining their global warming emissions over their "life cycles"-from the raw materials to make the car through manufacturing, driving, and disposal or recycling. Toward that end, we performed up-to date assessments of the carbon footprints of BEVs, taking into account the latest information about electricity generation and BEV models."

Tesla's Electric Cars Aren't As Green As You Might Think (Wired)
"But how green is a Tesla, really? Devonshire Research Group, an investment firm that specializes in valuing tech companies, dug into the data and concluded that Tesla's environmental benefits may be more hyped than warranted. Devonshire isn't saying that Tesla is pulling a Volkswagen, or that its cars are spewing greenhouse gases from invisible tailpipes. It's arguing that Teslas (and, by extension, all electric vehicles) create pollution and carbon emissions in other ways."

How Green Are Electric Cars? Depends on Where You Plug In (New York Times)
"According to a report that the Union of Concerned Scientists plans to release on Monday, there would be a considerable difference in the amount of greenhouse gases - primarily carbon dioxide - that result from charging the cars' battery packs. By trapping heat, greenhouse gases contribute to climate change."
