Step-by-step explanation:
The carbon footprint, as related to sustainability, is a measure of the impact on the environment based on the amount of greenhouse gases generated.
Carbon dioxide, methane, nitrous oxide, and water vapor are examples of greenhouse gases that trap heat in the atmosphere and contribute to global warming, air pollution, and extreme weather conditions. The carbon footprint is influenced by human activities, such as the burning of fossil fuels, deforestation, and industrial processes, which release these greenhouse gases into the atmosphere.
