Carbon footprint

Definition

A carbon footprint is the total amount of greenhouse gases, primarily carbon dioxide, that are emitted directly or indirectly by an individual, organization, event, or product, usually expressed in equivalent tons of CO2. It serves as a measure of the impact of human activities on the environment, particularly in relation to climate change and global warming.
