Life cycle screenings of two food products

Life cycle screening, defined as the initial data collection and interpretation of the environmental effects of a product system, is applied to two food products. Examples of the results are given and some methodological suggestions are given to simplify the procedures related to product definition, geographical origin and co-product allocation. It is suggested that life cycle studies of food products may be more easily performed and their results become more comparable if industrial conventions can be agreed to on these aspects.
