摘　　要：本研究预测了截止2060年的塑料使用、塑料垃圾产量及环境泄漏量,讨论了塑料循环一揽子计划情景(抑制行业需求、加强循环回收、降低管理不善)对不同经济发展区域实现循环、缓解污染的作用.研究发现:如果塑料行业按现状发展,到2060年塑料的环境泄漏量较2022年预计会翻一番但实施塑料政策可以有效地限制全球塑料使用和废弃物的增长趋势(减少近23%),改善塑料使用的循环性(2060:回收,+30%)并减少塑料的环境泄漏(2060:管理不善,-15%).塑料政策中的所有方案都有助于减少管理不善的废弃物,预计泄漏到环境中的塑料将减少64.09%.政策情景使得塑料的环境泄漏与使用量间相对脱钩,这意味着塑料的环境泄漏将不再直接受使用量影响.未来的政策构建可以转向强化回收及废物处理结构管理,推进全球可持续发展.This study provides an overview of plastic use,waste,and environmental leakage to 2060.The role of plastic policy scenario implementation(curbing industry demand,enhancing recycling,and reducing the mismanagement rate)in mitigating plastic pollution is illuminated.The research found that if the plastic industry continued as it is,it would remain unsustainable.Environmental leakage of plastic would be expected to double by 2060 compared to 2022.Implementing plastic policies could limit the global growth trend in plastic use and waste(nearly 23%reduction),improve the recyclability of plastic(2060:recycling,+30%),and reduce the environmental leakage of plastic(2060:mismanagement,-15%).The policies consider several scenarios,all of which would contribute to the reduction of mismanaged waste,with a 64.09%reduction in plastic leaking into the environment project.Policy scenarios make the relative decoupling between the environmental leakage and the use of plastic,which conveys that the environmental leakage of plastic will no longer be directly affected by usage.Future policy construction can turn towards strengthening recycling and disposal structure management to achieve sustainable development.
