At Home: Use Less Energy
Home energy accounts for 21 percent of America's global warming pollution. If we make smart choices, we can cut more pollution than the entire emissions of over 100 countries!

• Change a bulb: Better energy-saving lights
• Greener power: Re-thinking home energy
• Full list of tips: How to cut pollution at home

On the Road: Be Efficient
When it comes to global warming, how and what we drive are two of our most powerful choices. Transportation is the biggest source of U.S. carbon dioxide emissions, more than factories or homes. 

• Save fuel: Use less gas with your current car.
• Choose green: Buy a clean, efficient car.

Neutralize the Rest

• Even if you are already driving efficiently and using less electricity, there's more you can do. Buying offsets, or credits, neutralizes what we can't cut. How to buy carbon offsets.
