Fuel-efficient cars the best way to fight climate change, researchers say

February 17, 2016 by Bernie Degroat

While Americans can do a lot of little things in their daily lives to help reduce carbon emissions, driving a vehicle that gets better gas mileage is by far the best way for an individual to combat climate change, say University of Michigan researchers.

A new study by Michael Sivak and Brandon Schoettle of the U-M Transportation Research Institute examines how individuals can contribute to reductions of five man-made sources of , without substantial effort and time and little alteration to one's lifestyle, if any.

These sectors include: industry, commercial, residential, agriculture and transportation.

It is the latter three sectors where individuals can make the greatest impact, the researchers say. For comparison, the following actions related to transportation would each reduce total emissions by 0.2 percent, if performed by each American driver: reducing driving by 1.25 percent, buying a vehicle that gets 21.7 mpg instead of the current average of 21.4, using tires with rolling resistance that is 9 percent better that the current average, reducing the frequency of very high-speed driving or aggressive driving by 25 percent, or reducing the amount of flying by 10 percent.

On the residential and agricultural fronts, a reduction of 0.2 percent of total emissions could be achieved by turning the thermostat down 3 degrees for eight hours a day, replacing 20 percent of the existing incandescent bulbs with LEDs, cutting food consumption by 2 percent, decreasing meat consumption by 7 percent or reducing the amount of discarded food by 13 percent, according to Sivak and Schoettle.

"However, to achieve larger reductions in emissions—-5 percent to 10 percent—there is only one realistic action that by itself would accomplish the goal. And that is a more-fuel efficient vehicle," Sivak said.

If every American driver bought a vehicle that gets 31 mpg instead of the current average of 21.4 mpg, total emissions would decrease by 5 percent, the researchers say. Buying a that gets 56 would result in a 10-percent reduction.

Are your science gods also only 99% certain the planet isn't flat?

REAL? If a climate change Armageddon was "real" then science would have agreed it was as real as smoking causing cancer not "99% real". Deny that. 35 MORE years of debate, denial and climate action failure is certain and unstoppable.
*Even Occupy no longer mentions CO2 in it's list of demands so follow the herd sheeple.

Is this how you climate drama queens want your kids and history remembering you?

anti stopped posting on the other thread where he sarcastically asked for proof of my work for NASA. After I gave it to him, he disappeared.

Now, he/she tries to find something else to denigrate, but he/she can't.

anti, I suggest you back up your words with action, like I did.

Denigrate...REALLY!!
If I did not know better I would say you were schizophrenic but then, it's quite obvious you are the only one who remain oblivious of your talent for deceit. Hence, the poor attempt to deflect.
Now let's see how much you are saving the environment by telling us what was the annual mileage in your Toyota.

Tell us Senior Engineer, how do you compare an EV with an IC vehicle?
gkam
1 / 5 (5) Feb 19, 2016
IC vehicles are now losers for some applications, such as ours. Not just no gas, but no oil, and no leaks, and no filters. We just went through what is probably the only consumable, windshield washer fluid. No tune-ups, ever. No transmission. The first time the dealer sees it is after 20,000 miles. Quiet and really peppy, since it has full torque at zero speed. We "fill it up" at home, usually at night.

No contest in that environment. Others will not be so lucky because of climate or latitude, or applications/needs.

Lemmee tell you penny-pinchers what will sell it to you: Regenerative Breaking. When you see the car "brake" by turning the engine into a generator, you will not be able to take your eyes off the gauge. This one has four stages of regen, and we drive in #3. Taking the foot off the gas pedal puts the momentum proportionally into the battery as more miles. If your trip is slightly downhill, you can put miles into the battery instead of using it. It also saves the 4-wheel disks.
