There are lots of ways to reduce your carbon footprint, or the amount of greenhouse gas emissions you generate as a result of your daily life. Trade in your car for one with better gas mileage, for example. And walk, bike, or take public transportation whenever possible.

Emissions of two air pollutants from the U.S.'s largest electricity generators have fallen since 1990, while emissions of carbon dioxide, the most significant human-caused greenhouse gas, have been steadily rising, according to new research.

CO2 is not subject to government regulation.
