全球有机产品贸易的增长增加了对生产和运输过程中环境影响评估的需求。在一项案例研究中，使用生命周期评估方法确定了中国生产并进口到丹麦的有机大豆的环境热点。此外，案例研究还比较了有机大豆和传统大豆在农场门口的环境影响。丹麦进口的每吨有机大豆的全球变暖潜能值 (GWP) 总额显示，51% 来自运输，35% 来自农场。在农场门口比较有机大豆和常规大豆表明，每吨有机大豆的全球升温潜能值、不可再生能源使用、酸化和富营养化较低，而土地使用略高。 (C) 2010 Elsevier Ltd. 保留所有权利。
Growing global trade with organic products has increased the demand for environmental impact assessments during both production and transport. Environmental hotspots of organic soybeans produced in China and imported to Denmark were identified in a case study using a life cycle assessment approach. Furthermore, environmental impacts of organic and conventional soybeans at farm gate were compared in the case study. The total global warming potential (GWP) per ton organic soybeans imported to Denmark revealed that 51% came from transportation and 35% from the farm level. Comparing organic and conventional soybean at farm gate showed that GWP, non-renewable energy use, acidification and eutrophication was lower per ton organic soybeans, whereas land use was slightly higher.
