Environmental groups say new fuel economy standards will reduce US oil dependence and air pollution

August 29th, 2012

New gasoline standards for cars and light trucks set by the US Department of Transportation and the US EPA won final approval on Tuesday after several months of public review and hearings.

The new mileage standards will require that American cars get an average of 54.5 miles per gallon by 2025. The EPA touted the change as a near doubling of fuel efficiency for cars, and predicted the effect on consumers would be like lowering the price of gasoline by $1 a gallon. Overall, the measure will save consumers more than $1.7 trillion at the gas pump and reduce U.S. oil consumption by 12 billion barrels, according to the EPA.

Be part of the solution: Travel lighter

After running our households, transportation is the second biggest way we humans degrade the environment. If we were traveling in droves, on say trains, it wouldn’t be so bad. But our penchant to scoot around solo or in small groups in gas-fueled vehicles has left an impressive scar on the globe. Starting with the paved roads that carve up wildlife habitat, and ending with those recently popular luxury SUVs that spurn air quality with their single and low double digit gas mileage, automobiles have created a huge carbon footprint.

Find your car’s emissions and greenhouse gas ratings

May 19th, 2009

From Green Right Now Reports

How do cars pollute? In two main ways, through inefficient mileage (guzzling a gallon of gas every eight or 10 or 14 miles) and through tailpipe emissions.

There’s the pollution associated with manufacturing, also, but to keep it simple let’s stick with emissions and mileage. Obviously, both affect the air. Think of mileage as a measure of your car’s pollution volume over time – if a gallon of gas doesn’t take you very far, you have to burn a lot more gas — and emissions as the chemistry of that pollution; if the mix is particularly noxious, your car will be a bigger offender than one with better tailpipe controls.

So if you want to buy the cleanest car you can — in the price range you need — you’ll look at both factors. Fortunately, the U.S. Environmental Protection Agency has already done this work, assigning a “greenhouse gas” score to most models. Find it at the EPA’s Green Vehicles website.

GM’s 20/20 vision

February 18th, 2009

By Barbara Kessler
Green Right Now

There’s a chart on that’s a graphic illustration of what happened to GM. The chart is a compilation of 2009 hybrid vehicles. It lists 27 hybrid vehicles in descending order from the highest mileage cars to the lowest.

At the top of the chart, perch some of the highest mileage vehicles available on the market, the Toyota Prius, the Honda Civic and the Nissan Altima. The top two clock in at 40 mpg and up. The Altima at 33-35 mpg.

The lowest mileage vehicles reside at the bottom of the chart. And the bottom five are all GM products: The GMC Yukon, Chevy Tahoe, GMC Sierra, Chevrolet Silverado and Cadillac Escalade.

Engine Idling: A Standard Practice Gets Re-Examined

August 11th, 2008

By John DeFore

Not long ago, a City of Austin crew spent the day installing new “No Parking” signs along the streets of my neighborhood. Two big Ford F450 trucks sat outside my home-office window for hours while the men dug holes and planted posts — and their engines ran the entire time.

Not wanting to be the block’s eco-scold, I said nothing as the trucks rumbled. But the waste of fuel nagged at me even after the noise was gone, and I eventually called the city to find out why workers would be allowed to run their engines like that. Surely the city didn’t approve of polluting the air all morning just so the truck would be pre-air-conditioned when workers took a coffee break?

After calls to three or four city departments, I found a public works supervisor with some answers. All work trucks keep their engines running, she told me, because of the LED arrow boards mounted on them which warn drivers to keep their distance. “You can’t turn the engine off and keep the arrows going, because your battery will die down,” she said.

It was easy to see how a safety-based practice might serve as an excuse to keep the cab cooled off, even when running the arrow was unnecessary: In my case, the truck was parked on a dead-end block where no traffic could approach from behind it. The woman I spoke with agreed that conserving fuel wasn’t the easiest topic to raise with work crews. “They’ve been here a while,” she said, “and when I mention this they kind of get, ‘Well, fine, what do you want us to do for safety?’”
