A carbon footprint quantifies the total greenhouse gas emissions produced by individuals, organizations, or products, primarily from fossil fuel combustion. It encompasses direct emissions (Scope 1), indirect emissions from purchased energy (Scope 2), and other indirect emissions (Scope 3), with the latter being the most challenging to measure. Reducing carbon footprints is essential to mitigate climate change impacts, which include global warming, resource depletion, and severe weather conditions.
