What Is Measured In The Free Calculator:

  • This free carbon calculator provides a summary of some of the common GHG emissions and is suitable for businesses wanting to get an idea of their potential GHG emissions prior to taking the step to become carbon positive certified.

  • Be aware that many other online calculators often only show CO2e emissions. Both our free & full version calculators follow the GHG protocol (when measuring data is available) with a breakdown of emission gas types and totals expressed in CO2e. CO2e stands for carbon dioxide equivalent (includes CO2, NO2, CH4)

  • The data you enter into the calculator should reflect the GHG emissions that you / your organisation has directly or indirectly created over a 12 month period. 

  • The free calculator cannot be used towards carbon positive certification as it does not cover all of the emissions that are shown in our full version calculator. Our full version calculator also a breakdown of the emissions into scope categories (scope 1, 2, 3) that is required to follow the GHG protocol standards (see the Standards section in 'Become Certified').
