This document discusses how to calculate the marketing value of Green IT initiatives. It suggests that rather than counting tonnes of carbon emissions reduced, one should count the number of "Toms" saved, where one Tom is equal to one tonne of carbon emissions saved per person per year. The document provides some examples of potential carbon savings from various transportation options in Toms to illustrate how one can quantify the marketing value of Green IT programs.
