Anything to raise the price of gas to stiffle the american public.
Check it out:

The Environmental Protection Agency on Monday issued stricter emissions standards for cars and trucks that limit the amount of sulfur that can be used in gasoline.

EPA officials hailed the new standards, which they said would prevent as many as 2,000 respiratory deaths per year while imposing minimal costs on refiners and automakers.

The American Petroleum Institute (API), however, said the standards would raise gas prices while providing little environmental gain. The group also said a 2017 deadline for meeting the standards could cause an interruption in supply.

“Besides the enormous costs and negligible environmental benefit, we are also concerned about the timeline of EPA’s new rule,” said Bob Greco of the American Petroleum Institute.
