Hybrid Carbon Footprints are a significant advance in terms of speed and accuracy of carbon foot printing.
There are 3 ways of calculating the carbon footprint of a product or organisation:
In the majority of cases Input - Output models are more than good enough and provide a good first level calculation of carbon footprints. For products that are used in very high volume, a second or third level calculation is appropriate and this is where hybrid models come in to their own, by providing another level of accuracy.
