|The study was conducted for the German Enquete-
Commission for theprotection of the atmosphere by an interdisciplinary working group for
agriculture and the food system in Germany. Besides the description of the status quo
proposals were made for the reduction of negative climatic impacts with view to
agriculture and nutrition.
The negative climatic impact in food processing is 6% lower as compared to agriculture. This is due to modern technologies in food processing which have lead to energy reductions of 30% and also to reduced direct climatic relevant emmissions in recent years. Within the food system processing of sugar (22%), drinks (22%) as well as noodles and bakery products (26%) are contributing most to negative climatic impacts.
Of relevance is also the distribution of the produced and processed foods with a total of 10% of the negative influences. The expectation of food availability at any time of the year and at any place in the world, the trend to highly processed foods and the alteration in food preparation techniques contain the danger of a tremendous potential to an increasing energy consumption. It is, therefore, clear that the highest potentional for the reduction of climatic relevant gases in the area in food processing and nutrition lies in the food habits of consumers. These activities (shopping, foodpreparation etc) account for 75 mio. tons CO2 equivalent. Therefore, on the bases of three case studies the possibilities for the reduction of climatic relevant emmissions were studied: 1. consumption of apples(regional/seasonal versus asaisonal) ; 2. comparison of menues with and without meat; 3. convenience menue (pre-prepared products) versus directly prepared menue (fresh products). These examples showed a clear advantage for regional and seasonal whole food nutrition.
