How do we know our carbon footprint calculation is accurate?

    Carbon footprint calculations are based on information like average emissions, and is not going to be an absolutely accurate reflection of your impact on the planet. One service, with link given below, has the following disclaimer: “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.”

    There are many companies and organizations which provide carbon footprint calculations, all of which use different methods (but usually with the same data). Examples include The Carbon Trust (, The Carbon Footprint (, Nature Magazine (, the EPA ( and many more. I suggest taking several and finding your average for the best idea of what your carbon footprint could be!
