Keeping track of your Carbon Footprint is actually the summation of the Carbon Weights of all products and services your consume. Calculating these individual Carbon Weights has been left to large collection of different Carbon Calculators. Each Carbon Calculator represents a trade-off in simplicity versus reality. This means that all of them help you begin to see your individual Carbon Footprint, but none can capture the full list of products and services that you consume that have an impact. Since the Carbon Weight of everyday things is not known, these calculators provide best guess estimates of your actual Carbon Footprint.
