Calculate Your Carbon Footprint and Offset

Carbon Calculator Station


All the food on this website it calculated in grams. There are a 1000 grams in a kilogram.


Create a balanced meal that you would want to eat with the highest and lowest carbon footprint.


Multiply the highest and lowest carbon measurements in the meals you found by the number of participants (ex: 100 participants). How many trees would you have to plant to make this meal carbon neutral for the whole conference?


NOTE: Tree offset calculation is based on a tree planted in the humid tropics absorbing on average 50 pounds (22 kg) of carbon dioxide annually over 40 years2  – each tree will absorb 1 ton of CO2 over its lifetime; but as trees grow, they compete for resources and some may die or be destroyed – not all will achieve their full carbon sequestration potential. This calculator assumes that 5 trees should be planted to ensure that at least one lives to 40 years or that their combined sequestration equals 1 ton.
