Remark : This calculator takes into account three greenhouse gases: carbon dioxide (CO₂), methane (CH₄) and nitrous oxide (N₂O). To measure the impact of their combined action on the climate, we use a common unit : the tonne of CO₂equivalent. It is obtained by comparing the global warming potential of a greenhouse gas to that of CO₂ over a given period (usually 100 years).
