When electric cars first arrived in 2011, it was a reasonable question: Aren't you just shifting emissions from the tailpipe to the smokestack? The answer is yes, but the carbon emissions per mile of an electric car—properly measured on a wells-to-wheels basis—are virtually always lower than those of a gasoline or diesel car. It's not... Electric cars emit less carbon than average U.S. new car, everywhere in the world
When electric cars first arrived in 2011, it was a reasonable question: Aren't you just shifting emissions from the tailpipe to the smokestack? The answer is yes, but the carbon emissions per mile of an electric car—properly measured on a wells-to-wheels basis—are virtually always lower than those of a gasoline or diesel car. It's not... 
When the Environmental Protection Agency quietly issued its new four-year plan in mid-October, the phrase "climate change" did not appear anywhere in the 38-page document. It is now clear the Trump Administration intends to delay, halt, or erase government efforts to limit U.S. emissions of carbon dioxide, the global-warming gas that is the main... 
Donald Trump's White House appears to be readying another of its next big climate change overhauls, and like many of the administration's plans, it will weaken or eliminate regulations on industry. Specifically, President Trump touted the undoing of the Clean Power Plan at a rally in Huntsville, Alabama, which foreshadowed a formal announcement... 
The prospect of bans on gasoline and diesel new-car sales have become a much greater threat not only to automakers but to oil companies as well, now that China has said it is studying such a move. The world's largest car market has not announced any timetables for such a ban, which will likely be implemented to give domestic automakers the maximum... 
Mazda is a tiny carmaker on a global scale, producing just 1.6 million vehicles a year. It competes with four companies (GM, Nissan-Renault, Toyota, and VW Group) that each sell around 10 million a year, as well as numerous other smaller makers still larger than Mazda. In a world where reducing the carbon emissions from road vehicles is... 
Sometimes it's best not to dare the public to do the research, especially if you're trying to persuade them of something that isn't true. Almost two years ago, Inside Climate News published a significant expose that confirmed Exxon's own scientists had agreed that human carbon emissions contributed to global warming as early as July 1977. But as... 
On August 10, the U.S. Environmental Protection Agency announced it would reopen the Comment Period for the vehicle-emission standards for model years 2022 through 2025 it had finalized in January. The auto industry and its lobbyists had complained that the agency had moved too quickly, despite its issuance last summer of a voluminous Technical... 
As corporate average fuel economy requirements that started in 2012 continue to tighten, automakers have turned to an entire arsenal of tactics to reduce the fuel their vehicles burn. Downsized and turbocharged engines, transmissions with many more gears, lighter-weight structures, better aerodynamics and more all add incrementally to efficiency... 
The best analog to EPA administrator Scott Pruitt's latest action might be for the U.S. Geological Survey to undertake a "scientific critique" of theories that the world is round. After all, numerous authoritative sources over the years have raised doubts that the Earth is not flat. Surely their views deserve to be aired. Late last week, it... ![Electric-car wells-to-wheels emission equivalencies in MPG, May 2017 [Union of Concerned Scientists]](http://images.hgmsites.net/tmb/electric-car-wells-to-wheels-emission-equivalencies-in-mpg-may-2017-union-of-concerned-scientists_100608699_t.gif)
Electric cars have no tailpipe emissions when running. But unless they're charged entirely on renewable energy—still statistically unlikely today—there are emissions associated with generating the electricity used to charge their batteries. For several years now, rigorous "wells-to-wheels" analyses of the carbon-dioxide emissions...
