Although filling the MUGO calculator for estimating one's lifestyle's carbon footprint is simple, the calculations and data we used to build this algorithm are numerous and complex.
Let's try to summarize how it works:
a) to begin with, we use as basic values those of the carbon footprint per capita of the country and region in which the user lives. These are derived from scientific studies which analyze the average consumption of each inhabitant on 200 different categories of products and services in Europe ( consumption based carbon footprint calculated with a MRIO analysis "multiregional input-output");
b) based on further processing, this data is updated thanks to the questionnaire's 7 response sections which investigate: geographical area of residence, house and energy used, diet, land transport (cars, motorcycles and public transport), flights, clothing, electronics.
c) with the inputs coming from the questionnaire, the initially identified average values are replaced with ad hoc calculation based on the answers , thus obtaining a more precise value of the individual's carbon footprint. In case of missing information (even in the case of partial inputs), the average data of the region are always maintained.
d) we, therefore, present a report showing the carbon footprint in tons of CO2e with related equivalences and breakdowns of the data, in order to allow a better understanding of the impact that everyone's lifestyle has on the climate.
MUGO provides users with the results of calculations and analyzes carried out on a " best effort basis ". This is an estimate that is intended to be as accurate as possible but limited by the impossibility of fully and exhaustively tracking the user's consumption habits and the calculation approximations necessary to create a tool that can be used by each user.
