The Carbon Diet is a self-funded project aimed at creating an advanced carbon footprint calculation tool, intended to provide users with the level of information they require in order to produce effective behaviour change. Using accurate regular data, the site calculates a daily carbon footprint, so that users can see very quickly how their daily actions affect their impact on the environment. The site is developed using a "Getting Real" approach; the first version went online in June 2007, and additional functionality has been rolled out regularly since then.
