We provide a free carbon emissions calculator for businesses wanting an idea of their potential emissions before making the decision to become carbon positive certified. Please note, this sample calculator does not contain all the values for measuring your business emissions & so it should not be used to accurately measure or offset your emissions. For a full emissions calculator please contact us here.

Please see the following information before downloading the calculator at the bottom of the page

What Is Measured In The Free Calculator:

  • Our free carbon calculator provides a summary 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.

  • Unlike some basic online calculators, our calculators follow the GHG protocol with a breakdown of emission gas types and totals expressed in CO2e (carbon dioxide equivalent), covering CO2, NO2, CH4.

  • Enter data reflecting the GHG emissions created directly and indirectly over a 12 month period. 

  • This calculator does not cover all the emissions required for carbon positive certification. Our full version calculator includes 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').
