PARALLEL SESSION 4B: DIET 8 th Int. Conference on LCA in the Agri-Food Sector, 1-4 Oct 2012 salmon, cheese, milk and eggs on a per kcal basis are relatively similar, but applying the NuVal based “nutritional weighting” clear differentiates these foods on a per nutritional kcal basis. The influence of a “nutritionally weighted” functional unit is perhaps clearer in more extreme comparisons. Coca-Cola reports that their product delivered in 2 L plastic bottles has a carbon footprint of 0.25 kg CO2e/ L (Coca-Cola Co., 2010), which, on a caloric content basis, is a factor of 3 smaller than whole milk. Coca-Cola receives a NuVal score of 1, however, so on a nutritionally weighted basis, the carbon footprint of Coca-Cola is 17 times greater than that of whole milk. 5. Conclusion We propose a functional unit that addresses a primary function of food, which is to deliver healthpromoting nutrition. The NuVal score, which evaluates multiple nutritional properties of food, provides a convenient basis for more comprehensive comparisons of life cycle environmental sustainability performance across diverse food types.

The NuVal score is based on empirically derived weighting factors that currently remain confidential; thus, the nutritional factors that are the major drivers of the NuVal score are not immediately apparent. This approach to establishing a nutritional equivalency metric for environmental impact studies of food is intended to stimulate and encourage discussion and further exploration of an important topic. Given limitations to the approach presented here, extreme care must be taken in fully communicating, and further considering, the meaning of a “nutritionally weighted kcal.” Other similar nutritional indicators, such as the Nutrient Rich Foods Index (Drewnowski, 2010), may warrant consideration. Ultimately, it may be more beneficial to consider nutritional equivalency and environmental impact of foods by aggregating to the whole diet level. Given a diversity of research goals and the complexity of food and agricultural systems, there are likely many ‘correct’ answers to the question of food functional equivalency; our hope is that the approach presented here provides practitioners with an additional tool to consider. 6.
