Against the background of increasing awareness and appreciation of issues such as global warming and the impact of mankind's activities such as agriculture on the global environment, this paper updates previous assessments of some key environmental impacts that crop biotechnology has had on global agriculture. It focuses on the environmental impacts associated with changes in pesticide use and greenhouse gas emissions arising from the use of GM crops. The adoption of the technology has reduced pesticide spraying by 503 million kg (-8.8%) and, as a result, decreased the environmental impact associated with herbicide and insecticide use on these crops (as measured by the indicator the Environmental Impact Quotient [EIQ]) by 18.7%. The technology has also facilitated a significant reduction in the release of greenhouse gas emissions from this cropping area, which, in 2012, was equivalent to removing 11.88 million cars from the roads.
在人们对全球变暖等问题的认识和重视程度不断提高，以及人类活动（如农业）对全球环境的影响不断增加的背景下，本文更新了之前对作物生物技术对全球农业产生的一些关键环境影响的评估。它重点关注与使用转基因作物导致的农药使用和温室气体排放变化相关的环境影响。该技术的采用使农药喷洒量减少了 5.03 亿千克（减少了 8.8%），因此降低了与这些作物上使用的除草剂和杀虫剂相关的环境影响（通过环境影响指数[EIQ]来衡量）18.7%。该技术还有助于显著减少该种植区温室气体的排放，相当于 2012 年从道路上减少了 1188 万辆汽车的排放量。
