How do I calculate my carbon footprint?

Modified on Thu, 05 Oct 2023 at 03:25 PM

You can calculate your carbon footprint by using an online carbon calculator. There are a number of calculators that can help you to measure and understand the impact of your activities. 


1: Reduce your emissions where you can. We won’t reach global net-zero without a collective effort. Decarbonisation is critical at work and at home. 

2: Determine the number of credits you need:

  • Business emissions: There are specialist organisations that support companies with assessing business emissions. You can find more information through ICROA, The International Carbon Reduction and Offsetting Accreditation. 
  •  Travel emissions: Use the ICAO calculator to identify the amount of CO2 emitted by your flight.
  •  Personal emissions:

USA: CoolClimate Calculator

World Bank’s estimates of average emissions per capita:

  • 1 tonne a month or less: Most European countries, emerging economies and developing countries
  • 2 tonnes a month: Australia, Canada, Estonia, Luxembourg, United States + several oil exporting countries
  • 3 tonnes a month or more: Curacao, Kuwait, Qatar, Trinidad & Tobago


Also, many governments have environmental departments that provide tools and calculators to help you calculate your emissions. You can also find a list of reputable carbon consultants on the International Carbon Reduction and Offset Alliance website:
