This paper updates previous assessments of the environmental impacts associated with using crop biotechnology in 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 since their first widespread commercial use over 20 years ago. The adoption of GM insect resistant and herbicide tolerant technology has reduced pesticide spraying by 671.4 million kg (8.2%) 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 18.4%. The technology has also facilitated important cuts in fuel use and tillage changes, resulting in a significant reduction in the release of greenhouse gas emissions from the GM cropping area. In 2016, this was equivalent to removing 16.7 million cars from the roads.

1996-2016年转基因作物使用对环境的影响：对农药使用和碳排放的影响。

本文更新了以前对与在全球农业中使用作物生物技术相关的环境影响的评估。自20年前转基因作物首次广泛用于商业用途以来，它着眼于与使用转基因作物引起的农药使用变化和温室气体排放相关的环境影响。采用转基因抗虫和耐除草剂技术使农药喷洒量减少了6.714亿公斤（8.2％），因此减少了与除草剂和杀虫剂使用相关的环境对这些农作物的影响（按指标“环境”衡量）。影响商（EIQ））提高了18.4％。该技术还大大减少了燃料的使用和耕作变化，从而大大减少了转基因作物种植区域的温室气体排放量。
