  1. Random gripe: Who came up with the term “carbon footprint” anyway, and how did it get so popular? If you think about it, it makes no sense. How is a quantity of CO2 a “footprint”?

    Why don’t they talk instead about “ecological footprints,” the amount of land it takes to support your lifestyle (including, I think, absorbing all the CO2 that you personally generate)? That term, I’m pretty sure, predates “carbon footprint,” it’s a better metaphor (since footprint = area), and it’s a more meaningful thing to visualize (since you can compare your footprint with the amount of land on Earth per person, whereas most people don’t have any idea what the consequences are of saving X tons of CO2).

  2. Buzzard asks:

    Who came up with the term “carbon footprint” anyway, and how did it get so popular?

    The clever men at Oxford offer this as the earliest recorded use of the phrase:

    1999 BBC Vegetarian Good Food Apr. 86/2 To cancel out the damage we do, Morrell believes we should plant trees, and that in doing so an individual or organisation can erase their carbon ‘footprint’.

    I have been unable to discover who this Morrell may have been, but at any rate, the possibility exists that the person who came up with the term “carbon footprint” was a vegetarian.

    The OED does not believe, however, that software engineers can speak English. In this it may well be entirely correct; certainly I have never encountered any evidence to the contrary.
