As the effects of climate change become clearer and more ominous, fossil fuel companies face a choice: Defy warnings of catastrophic climate change, or envision their roles in a post-carbon world.
Conflicting fuel standard reports from the Trump and Obama administrations disagree by billions of dollars.

Manufacturers always have to make trade-offs when they design new cars, balancing the need to protect public health and the environment with their urge to wow customers.
Fuel economy and air pollution regulations have lowered pollution and pushed industry to innovate.

The Trump administration announced a plan to relax fuel economy standards, but well-designed regulations can drive clean car innovations that make U.S. industry globally competitive.
Everyone looks for price, but there are smarter ways to communicate fuel efficiency on car labels.

It’s all in the presentation: In studies, consumers were more apt to choose fuel-efficient vehicles depending on how the same pieces of information were displayed on labels.
The current EPA administrator says the agency should prioritize clean air and clean water, rather than deal with greenhouse gases.

EPA Administrator Scott Pruitt has said the agency’s purview should not include climate change, but a look at its history under both Republican and Democratic presidents says otherwise.
Gas is cheap and Americans are back on in their cars and trucks.

Many people thought U.S. gasoline consumption had already peaked. They were wrong. What happened?
In 2015, gas prices fell below $2 per gallon in Moscow Mills, Missouri. The trend of low gas prices across the United States delay a signature Obama proposal to reduce emissions from cars and trucks.

Faced with stringent fuel economy standards but cheap gas, automakers may seek to delay CAFE rules. What’s the best way to reevaluate these emissions-cutting rules?
Americans like big vehicles – a serious challenge to reducing emissions.

American consumers just aren’t prioritizing fuel efficiency in a time of low gasoline prices. Is there a way to reverse the trend and make progress on climate change?
While the higher gas mileage may lead people to drive a green car more often, its other attributes may be less appealing.

Some worry that efforts to reduce energy consumption by increasing fuel efficiency cause a so-called rebound effect that eats into the expected savings. We tested the theory.
