A 985 km car journey (for example between Lille and Bayonne), ten days of gas heating, 26 meat meals, the manufacture of a sofa bed or even half of a 45-inch television, etc. generate no less than 190 kg of carbon dioxide equivalent (CO2). With their numerous and varied activities (work, transport, leisure), comfort (electricity, heating) or daily necessities (food, water), the French person emits on average almost ten tons of CO2 per year. By performing this test You can calculate your climate footprint. Let's face it: 10 tons is too much. To protect planet Earth, all people should limit themselves to an average of two tons of greenhouse gases (GHG). To arrive at this calculation, the Agency for Ecological Transformation (Ademe) adds up our direct emissions (the energy used to start a washing machine, for example) and our indirect emissions (the materials used to manufacture the machine, its transport to various warehouses before arriving at our premises and its waste when it becomes inoperable).
