To start our adventure into sustainability, on 7 January 2020 I completed the free questionnaire on carbonfootprint.com and got the results below. There are a lot of generalisations in the questionnaire but as a mechanism for creating a comparison I think it is useful.
The questionnaire is for one person, so for our household (3 people) our household's carbon footprint is likely to be 3 times higher than my results. My results are for the year 2019 and I was as honest as possible but some estimation was required (eg how many miles I have travelled by bus).
Your Carbon Footprint:
House - 0.89 tonnes of CO2e
Flights - 0.51 tonnes of CO2e
Car - 1.98 tonnes of CO2e
Motorbike - 0.00 tonnes of CO2e
Bus & Rail - 0.02 tonnes of CO2e
Secondary - 2.67 tonnes of CO2e
