The Nature Conservancy’s carbon footprint calculator measures your impact on our climate.
Our carbon footprint calculator estimates how many tons of carbon dioxide and other greenhouse
gases your choices create each
year. more info
Carbon dioxide (CO2)
is the primary greenhouse gas in our atmosphere. This means that the
amount of carbon dioxide in our atmosphere directly influences how much
of the sun's heat stays in the atmosphere, which is a key factor in
climate change. One ton of carbon dioxide is released when you travel
5,000 miles in an airplane, drive 2,500 miles in a medium-sized car, or
cut down and burn a tree that was about one foot in diameter and 40 feet
tall. There are other greenhouse gases as well, such as methane and
nitrous oxide. This carbon footprint calculator includes these gases in
your results and reports them in a standardized measure called "tons of
CO2 equivalent."
To get started, select the number of people in your home:
There are
people in my household.
Then choose whether you want to calculate a carbon footprint for yourself or for your household:
Please select number of people and choose "For Me Only" or "For My Household".
