The Carbon Calculator

What are your carbon emissions?

Use our free online calculator to estimate your carbon footprint and find out how much you need to offset to compensate for your greenhouse gas emissions.

  • Please enter emission activity data for 12 months for each category.
  • We use emissions factors and averages for Australia.
  • For larger and more complex measurements we recommend our Carbon Advisors conduct a comprehensive emissions analysis. 

Contact us to measure other emissions, such as freight, that aren’t shown.
