CARBON FOOTPRINT IN SUSTAINABLE FOOD CHAIN AND ITS IMPORTANCE FOR FOOD CONSUMER

摘要

Freshness, sensory attributes and food safety are currently indicated as main criteria in respect to food purchasing decisions. However, growing number of consumers are ready to choose also environmentally friendly food products. Carbon Footprint (CF) expressed in CO_(2 )equivalent of greenhouse gas emission seems to be an innovative indicator useful to evaluate environmental impacts associated with production and distribution of food. The review carried out in this study is based mainly on data presented in papers and reports published in recent decade, including some opinions available on various internet websites. In this study are discussed some examples of CF values calculated both, production of primary raw materials, food processing stages, final products transporting and activities taken during food preparation in the household, as well. The CF indicator offers also a new tool to promote disposition of food products distributed e.g. through big international supermarket chains. Mostly due to the suggestion of ecological institutions, direct comparison of CF values for different food products leads even to postulate almost total elimination of less eco-friendly animal origin food (like red meat) from the diet of typical consumer. So, improving the state of consumers education in respect to environmental issues of whole food chain might effect not only their eating habits but also their health.
