The carbon footprint is a measure of the environmental impact of human activities, in particular greenhouse gas emissions from energy consumption, transport use, industrial and agricultural activities, and waste management.
The carbon footprint measures the emissions, in particular, of carbon dioxide (CO2), but also of other gases such as methane (CH4) and nitrous oxide (N2O), emitted into the atmosphere due to human activities.
The carbon footprint can be calculated at the individual, company or entire country level, and is expressed in tons of CO2 equivalent.
The calculation of the carbon footprint takes into account all phases of the life cycle of a product or service, from production to distribution, from consumption to disposal, and evaluates the energy used, the materials used, the distances travelled and other variables.
The carbon footprint has become an important tool in the fight against climate change, as it allows the identification of the main sources of greenhouse gas emissions and the identification of the actions needed to reduce them.
