Scientists agree that global warming is real, that its being caused by humans and that we need to dramatically reduce our emissions beginning immediately and through mid-century if we’re to avoid the worst consequences of a warming planet. This warming—which is leading to unpredictable weather patterns, drought and increased levels of ground-level ozone—is already having profound implications for New Mexico.

Over the last century, average annual temperatures in the Southwestern United States have increased. These changes have led to smaller snow packs and earlier snowmelts, decreasing available drinking water supplies and increasing the risk of spring flooding, summer droughts and more intense fire seasons.

Transportation is New Mexico’s second largest source of carbon dioxide pollution—responsible for more than one-quarter of the state’s emissions in 2000. And because there are more cars on the road and people are driving more, the problem is only getting worse. Putting cleaner cars on the roads in New Mexico is a critical first step toward cutting our global warming pollution.

Luckily, cleaner, more efficient car technology is available that reduces global warming and air pollution emissions, while saving consumers money at the pump.

The Clean Cars Program reduces global warming and air pollution emissions in three ways. First, it sets strong standards for emissions of toxic air pollutants. Second, its technology-driving component promotes advanced-technology vehicles such as hybrids and electric cars. Third, the program establishes fleet-wide average limits on emissions of pollutants that contribute to global warming.

Under the regulations, by 2016, new cars would emit 34 percent less global warming pollution and new trucks would emit 25 percent less. Tailpipe emissions of conventional air pollutants will also be reduced, making New Mexico’s air easier to breathe.

Cleaner cars are a win-win for New Mexicans. These vehicles reduce our dependence on foreign oil, save consumers money at the gas pump and protect pristine wild places from oil and gas development.
