Only option 1 has been tested to date to include the impact of product waste into the packing evaluation. Using an environmentally extended US Input Output model published by Suh (2004)the impacts of the Frozen foods sector was analyzed. A total of 165 sectors contributed to this sector. These were further grouped into those from the food, packaging (paper, plastics glass bottles etc) and transport sectors amongst others as shown in Table 1. In all categories the product impacts are dominant and in some cases constitute almost all the impact such as in land use and eutrophication potential. In other impact categories packaging can become significant from 4% to 10%. The variations between contribution from different sectors means that a fixed ratio of product to packaging impact would not be suitable. A second comparison of the impacts of breakfast cereal production compared to packaging shows similar results in Table 2 however the packaging impacts are larger than for frozen food products. This is due to the meat in frozen food products having substantially higher impacts compared to cereal grain which is the dominant ingredient of breakfast cereal.
