carbon copy

A person or thing that closely resembles another, as in Our grandson is a carbon copy of his dad. Originally this term meant a copy of a document made by using carbon paper. The linguistic transfer to other kinds of duplicate survived the demise of carbon paper (replaced by photocopiers, computer printers, and other more sophisticated devices). [c. 1870]

carbon copy

Also, cc. An exact duplication. The original carbon copy, long used for correspondence and other written materials, was made by placing a sheet of carbon paper between two sheets of paper, the top one to be copied onto the blank bottom sheet by pressure from a pen, typewriter, or other instrument. Although this type of duplication has become largely obsolete, replaced by photocopying and electronic printers, it survives in the abbreviation cc, used to signal additional recipients of a letter or e-mail. A 1981 film, Carbon Copy, uses the term in the figurative sense; in it a white man discovers he has a black son who wants to be adopted.

carbon footprint

The 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.’”
