    Examples of Carbon footprint


      The idiom "carbon footprint" is commonly used to refer to the environmental impact of human activities, particularly in terms of carbon emissions and their contribution to climate change. It is often used in discussions about sustainability and reducing one's impact on the environment.

      Origin of "Carbon footprint"

      The term "carbon footprint" originated in the early 1990s, when it was used in a research paper by William E. Rees, an ecological economist, and Mathis Wackernagel, a sustainability expert. They used the term to describe the impact of human activities on the Earth's natural resources.

      The term became popularized in the mid-2000s, as concerns about climate change and the environment grew. It has since become a widely used idiom in discussions about sustainability and environmental responsibility. The use of "carbon" in the term refers to the element carbon, which is present in carbon dioxide, a greenhouse gas responsible for trapping heat in the Earth's atmosphere and contributing to global warming. The use of "footprint" is a metaphor for the impact or mark left by one's actions.
