Summary

The aim of this broad conceived study was to analyse greenhouse gas emissions (GHGE) of more than 130 foodstuffs from two organic agricultural production methods (Organic premium brand and Organic EU-standard) as compared to conventional farming in Austria. The system boundaries of the life-cycle study ranged from agriculture and its upstream supply chain to the retailer, including changes in soil organic carbon (humus) and land use change. In conclusion, all organic products in both organic methods showed lower GHGE per hectare but also per kg of foodstuff than comparable, conventional products. Therefore, the product carbon footprint (PCF) of organic products was lower throughout the implemented study. Organic dairy products resulted in 10 to 21 % lower CO2-eq per kg of product than conventional foodstuffs, organic wheat bread showed 22 to 25 %, bread products 34 to 42% and organic vegetables 10 to 35 % lower CO2-eq per kg of product. Furthermore, this detailed calculation throughout the whole value chain pointed out “hot spots” of CO2-eq-emissions for producers and retailers with existing GHG reducing potentials.
