Carbon Calculator

What is your climate impact?

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

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.

Why do I need to create an account?

  • To save your calculations and access them later
  • To access the advanced features of the calculator
  • To offset your emissions and be carbon neutral
