Carbon footprint calculator

According to carbonfootprint.com, currently 1 tonne CO2e = 1 tree.

Use the calculator below to ascertain how many trees you need to plant in a year to offset your emissions.

“The amount of CO2e a tree will offset depends on many factors, such as the type of tree, where it is planted and the amount of room it has to grow. On average, one broad leaf tree will absorb in the region of 1 tonne of carbon dioxide during its full life-time (approximately 100 years).”
