10 minutes chrono to calculate your carbon and water footprint
Before you start
It's an individual test!
Answer the questions on your behalf, not for your household. Of course, some things are shared (in my home with my family, the car with my carpoolers): this will be taken into account when calculating your carbon footprint, so don't worry!
It's about your personal life, not your activity.
You start your test with a starting score.
This is calculated from default answers assigned in advance to each question. If you pass a question, these same answers will be taken into account.
Any other questions?
What's my carbon footprint?Cliquez pour afficher la réponse
It's a fact that the climate is warming because of human activity. Everything we consume, use and then throw away requires materials and energy. Whether it's during the production, use or end-of-life phase of the good or service. So all our activities contribute to greenhouse gas emissions. Some a great deal, others very little. But what is our impact, as individual citizens?
To estimate our own contribution to global warming (our "climate impact"), we usually calculate the carbon footprint of our individual consumption.
How is it measured?Cliquez pour afficher la réponse
With a unit with a barbaric name: the CO₂ equivalent. Carbon dioxide
, you know it: we breathe it out all day long, but it has no influence on the climate.
It's the machines that make our modern comforts and conveniences that emit massive amounts of it, so much so that we count it in thousands of kilos per year and per person, and therefore in tonnes of CO₂e!
💡 But what does that little e mean?Cliquez pour afficher la réponse
Other gases, especially methane
and nitrous oxide 
also warm the planet: we convert their warming potential into CO₂e to simplify measurement. Where does my footprint come from?Cliquez pour afficher la réponse
Driving a car, eating a steak, heating your home, getting medical treatment, buying a TV...
Our individual consumption footprint is the sum total of all the activities that make up our modern lives.
Why have we added the water footprint?Cliquez pour afficher la réponse
Water is a precious global resource. Like the climate, the water cycle is heavily impacted by human activities. We have decided to add the water footprint to our calculation model to help you understand this impact.
