Carbon calculator

TreeProject can help you meet your targets to reduce the impact of your paper use and your carbon emissions. Use the Paper Use and Carbon Emission Calculators and calculate how many trees you need to grow.

Carbon calculator

Car use:

how many thousands of kilometres do you drive per year on average?

is your car:

total emissions for car (tonnes CO₂):

Air travel:

how many return flights you have taken in the last 12 months?

short-haul:

medium-haul:

long-haul:

total emissions for flights (tonnes CO₂):

Electricity:

If you use electricity from a renewable source then skip this section and move onto Gas. Enter the value of your electricity bills below. If you can, use your bills for the whole year if you have them, as this will cover seasonal variations. If you do not have bills for the last twelve months, you can estimate your total, for example by taking the last quarterly bill and multiplying it by four.

Off-setting emissions:

number of trees required to be planted to offset emmisions for this year:

One "tree planted" corresponds to 41m² of oak woodland matured over a period of 100 years, as calculated by the Edinburgh Centre for Carbon Management. 39% of the carbon is in fact stored in the woodland soil. For details, visit www.eccm.co.uk/counting
