#GreenhouseGasEmissions

According to the Environmental Protection Agency, the auto industry outperformed national greenhouse gas emissions standards for a second consecutive year.

Mazda’s green vibes must just feel right with the Environmental Protection Agency, as the agency has proclaimed the automaker has the highest fuel economy and lowest greenhouse gas emissions of any automaker in 2013.

Though automakers still have a decade to hit the 2025 CAFE target average of 54.5 mpg, the Environmental Protection Agency proclaimed in a just-released annual report that the automakers were ahead of schedule in meeting said target.

The Environmental Protection Agency said Fiat Chrysler Automobiles’ Chrysler and Ferrari divisions, as well as Daimler’s Mercedes-Benz unit, bought greenhouse gas (GHG) credits to remain in compliance with the agency’s 2025 twin goals of 54.5 mpg and halved greenhouse gas emissions.

Before a gathering at a distribution warehouse in Maryland, United States President Barack Obama announced that his administration has set March 2016 as the deadline for the next round of fuel efficiency and emissions standards for medium and heavy trucks to meet compliance.

There’s all kinds of controversy over what makes a car “green” and what doesn’t. Some point to size and efficiency, crucifying Hummers and full-size trucks as criminals against the planet. Others point to lifecycle greenhouse gas emissions, battery-component mining pollution and other less-obvious measures to excoriate hybrids. In any case, TTAC’s scientific department isn’t well-funded enough to issue a comprehensive report on the subject. Forbes may not have tested cars itself, or dug into true “dust-to-dust” footprints, but it’s gone ahead and published a list of “America’s Dirtiest Vehicles” anyway. Let’s take a look, shall we?
