Sources of our calculations

The calculations for primary emissions are based on conversion factors sourced from:

• Department for Environment, Food and Rural Affairs (DEFRA) - UK
• Vehicle Certification Agency (VCA) - UK
• US Environmental Protection Agency (EPA) - USA
• US Department of Energy (DOE) - USA
• Green House Office - Australia
• Standards Association (CSA) GHG Registries - Canada

The calculations for secondary emissions are based on estimates developed by Carbon Footprint to illustrate the impact on the environment from your day-to-day activities. Your actual secondary footprint may in reality be either lower or greater than that estimated here. Your total carbon footprint is the sum of your primary and secondary emissions.
