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 throughout its lifecycle. This concept helps to quantify the environmental impact of human activities and provides a framework for understanding how various practices contribute to climate change. By analyzing carbon footprints, strategies can be developed to reduce emissions and promote sustainable behaviors across different sectors.
