Methodology behind the carbon footprint calculator

There are different ways to calculate the carbon footprint of an individual. If you have tried out more than one calculator, you have probably noticed that the questions differ and so do the results. The quick answer to this is that it depends on which data the calculator is based off, and what assumptions are made. For the GoClimate calculator, we have explained the rationale between the choice of underlying data and the calculations that we base the tool on in the Methodology, which can be accessed HERE

If there is anything in the methodology that you find questionable, please reach out to us! Let us know if you disagree, have a better source of data for something, or how we could improve. The calculator will change over time because emission factors are updated regularly, which means that your result can change in the future. It could also change if we find better data or an even better way to calculate. These adjustments are however most likely minimal, and the biggest change is what you do yourself!

We calculate Food with general values from a UK study, Flights are calculated with our own API, Car with emission factors provided by national sources (so that differs depending on where you are), and Housing are the most complex calculations based on national data on energy and electricity usage and national emission factors. To this, we add a national average for Personal consumption which is the clothes, furniture and other things you purchase, and a buffer for Public consumption which is infrastructure, hospitals, education etc.
