Calculator Instructions

Just 3 Easy Steps:
1. Fill in your estimates or numbers.
2. Click calculate.
3. Donate trees.

Enter exact figures into the left-hand columns or select one of the national averages in the second column. The CO2 generated by your use of fossil fuels is instantly tallied in the third column, while the number of trees it will take to remove that amount of CO2 is given in the last column. If you make a mistake or want to delete a factor from your total, enter a zero in the left-most columns as needed until a zero appears in the corresponding CO2 column. If you wish to start over, hit Reload or Refresh on your browser. Once you have filled in all the appropriate boxes, hit "Calculate and Verify" at the bottom of the page.
