چکیده انگلیسی:
Animal-based food supply chains lead to significant environmental impacts, which can be influenced by
production systems, distribution networks and consumption patterns. To develop strategy aimed at
reducing the environmental impact of animal-based food supply chains, the common environmental
hotspots among different types of food, the role of transport logistics and the consequence of end market
need to be better understood. Life cycle assessment was adopted to model three types of animal-based
food chains (beef, butter and salmon), with specific technologies, high spatial-resolution logistics and
typical consumption patterns for three markets: local, regional (intra-European) and international. The
results confirmed that the farm production stage usually had the greatest environmental impact, except
when air transport was used for distribution. Potentially, the role of end market also can significantly
influence the environmental impacts. To understand more, three improvement options were examined
in detail with regard to hotspots for climate change: novel feed ingredients (farm production stage), sustainable aviation fuel (transport and logistics stage) and reduction of wasted food (consumption and end
of life stage). Significant reduction was achieved in the salmon system by sustainable aviation fuel (64%)
and novel feed (15%). Minimizing food waste drove the greatest reduction in the beef supply chain (23%)
and the international butter supply chain can reduce 50% of GHG mission by adopting sustainable
aviation fuel. Combined interventions could reduce GHG emission of animal-based food supply chains
by 15% to 82%, depending on market, transport and food waste behaviour. The results show that ecoefficiency information of animal-based foods should include the full supply chain. The effective mitigation strategy to achieve the greatest reduction should not only consider the impacts on-farm, but also
detail of the downstream impacts, such as food distribution network and consumption patterns.
