About the Calculator

This questionnaire enables you to estimate the amount of CO2 (carbon dioxide) and other greenhouse gas emissions that you are responsible for, as a Business, over a 12 month period. You can then  explore ways in which you can reduce your effect on the environment.


You will see the term CO2-e used throughout this app. It stands for "carbon dioxide equivalent", and is a standard unit for measuring carbon footprints. Rather than identifying each greenhouse gas individually (CO2, NO2, CH4 etc), their effects are grouped together and expressed in terms of the amount of CO2 that would create the same amount of warming.


​You can leave the calculator at any time - whether you come back in 10 minutes or next month the data you have entered will still be visible and can be amended.


You will notice this symbol           throughout the calculator - run your mouse over it and relevant information will appear in a pop-up window

Your Business

By capturing this information you will be able to compare your carbon footprint with other companies in the same industry.

How many people are involved or employed in your Business?

Most studies worldwide use the household or business as their basic unit, but others to work out their statistics on a 'per-capita' basis. 

By capturing the number of people in your business we can compare our results to those generated by either method.
