Based on where they've been bought, the average EV's emissions are about equal to a 73-mpg car.

Zero-emissions vehicles accounted for about 3.5 percent of California new-vehicle sales last year, or almost half the state's mandated goal for 2025.

You've all been busy.

The Union of Concerned Scientists' Dr. Jeremy Martin gives a realistic look at the future of fuels both traditional and alternative.

Leilani Munter joins Neil deGrasse Tyson on Star Talk Radio to talk about racing, solar power, and dolphins.

Watchdog group says VW fleet's overall environmental impact may be 25% higher than previously thought.

Let's start with the good news. On average, any new car you buy in the US today will be 43 percent cleaner than any average new car in 1998. Here's some more good news, for Korea anyway, Hyundai-Kia has been named the cleanest automaker in the latest study by the Union of Concerned Scientists (UCS), which looked at 2013 model year vehicles sold between October 2012 and September 2013 from the top eight au

Plug-in vehicles, battery-electric cars and plug-in hybrids are cutting US gasoline use by 45 million gallons a year, which means Americans are already saving $100 million a year in refueling costs thanks to EVs. Now, imagine how those savings might look if startups like Aptera, Coda Automotive and Fisker Automotive had created

It's a solution that would please just about everyone, save Exxon. Find every American household that could theoretically get by with a plug-in vehicle, and make them buy 'em. The Union of Concerned Scientists (UCS) and Consumers Union says about 45 million households – about 42 percent of all the households in the US - could drive plug-in vehicles with "little or no change" in their driving habits. And more than half of those could go on just as they are today if they drove battery-electr

Americans are about to spend a lot of money on gasoline. If the number crunchers at the Union of Concerned Scientists (UCS) are correct, US drivers will spend a tidy $1.44 billion filling up for their Memorial Day travels as 31.2 million people use the long weekend to participate in the time-honored tradition of a road trip.

For those nostalgic for mullets, the Cosby Show and Oakland A's dominance, the Nissan Leaf may be for you.

It's easy to understand that, if you power your vehicle with electricity, you don't need to use as much gasoline. But, how much do you actually save, in terms of fuel costs and greenhouse gas emissions if you plug in instead of gas up?

Jim Kliesch, the Clean Vehicles Program research director for the Union of Concerned Scientists (UCS), is noticing a change. Instead of hyping marquee "green" cars, auto manufacturers are settling into a groove where they regularly show off packages of conventional fuel-saving methods that will allow them to bring more-efficient vehicles to market. These small changes add up to noticeable results, he said during an interview at the New York

Following the official announcement this morning that the new 2025 Corporate Average Fuel Economy standard would be set at 54.5 miles per gallon, our email box overflowed with something we rarely see: near-unanimous support. Everyone from the automakers to the Union of Concerned Scientists, from the United Auto Workers to the American people (through a study released today by the Pew Environment Group) seem to agree: Sebastian Blanco
