Do you travel regularly for leisure or want to offset your household emissions?

Join us in creating a more sustainable future. Measure your carbon emissions & offset them with New Zealand native trees.

We offer a free carbon emissions calculator for individuals wanting an idea of their potential carbon emissions. The measured results from the calculator can be used to offset personal emissions with New Zealand native trees here. Please note, this calculator cannot be used to obtain carbon positive certification. To become certified please contact us here.

What Is Measured In The Free Calculator:

  • Our free carbon calculator provides a summary of the common GHG emissions, and is suitable for individuals offsetting.

  • 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 or indirectly over a 12 month period. 

  • This does not cover all the emissions required for Carbon Positive Certification. Our full version includes a breakdown into scope categories (scope 1, 2, 3) that is required to follow the GHG protocol standards (see the Standards section in 'Become Certified').
