carbon footprintThe total contribution of carbon dioxide and other greenhouse gases by a particular activity, enterprise, or product. The increasing concern about the harmful effect of human activity on the environment has promoted the use of this term, which may soon be a cliché. The Boston Globe travel section headlined an article on “green” (ecologically harmless) vacations: “Leave Your Carbon Footprint at Home” (June 6, 2010). Gregg Hurwitz’s novel They’re Watching (2010) has the lines, “‘What’s a lifestyle coach do, exactly?’ I asked. ‘We’re working on reducing Keith’s carbon footprint.’”See also: carbonCarbon footprint
Carbon footprintA measure of the amount of carbon dioxide emitted through the combustion of fossil fuels that a community, industry, or other entity contributes to the atmosphere through energy use, transportation, and other means. A carbon footprint is often expressed as tons of carbon dioxide or tons of carbon emitted, usually on an annual basis. It is the total set of greenhouse gas emissions caused directly and indirectly by an individual, organization, event, or product. |
