Carbon Calculator

Every day, you produce greenhouse gases. These gases are measured in units of carbon dioxide. Your "carbon footprint" is the impact your activities have on the world's climate. Use this tool to assess where you're at today, so you can get on the road to lowering your carbon emissions.

 

Entering your email address is optional. If you do, we'll email your calculator results and sign you up to receive the latest in WWF's conservation news and urgent updates via e-mail. View our privacy policy.

 

This tool is geared for U.S. residents and the data is provided by the Berkeley Institute of the Environment.

Greenhouse gases are released to provide the energy you use to heat and cool your home, to heat water, and to run all your lights, appliances and electronic devices. You can make a big reduction in your carbon emissions by taking simple steps in your home and yard.

TIp: Improve Your Home

Plant a shade tree: Planting a shade tree blocks the summer heat and can decrease the energy you need to cool your home. Get the best results by planting trees to the west and southwest of your house.

How is this calculated?

It can take a lot of energy to produce food and to ultimately put it on your plate. Be aware of how much energy is required for your food and how your diet affects your carbon footprint.

Tip: Shop Smarter

Consume less animal protein. Producing animal protein and delivering to your table tends to generate more greenhouse gas emissions than alternatives. Reduce your carbon footprint by eating less animal protein, especially beef and cheese.
