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 why this happens, 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, and Car with emission factors provided by national sources (so that differs depending on where you are). Housing is using calculations based on national data on energy and electricity usage and national emission factors. Personal consumption, which is the clothes, furniture and other things you purchase, is based on a national average, weighted based on how much you purchase brand-new. To this we add a buffer for Public consumption which is infrastructure, hospitals, education etc.
