Plastic pollution is one of the most challenging problems affecting the marine environment of our time. Based on a unique dataset covering four European seas and eight European countries, this paper adds to the limited empirical evidence base related to the societal welfare effects of marine litter management. We use a discrete choice experiment to elicit public willingness-to-pay (WTP) for macro and micro plastic removal to achieve Good Environmental Status across European seas as required by the European Marine Strategy Framework Directive. Using a common valuation design and following best-practice guidelines, we draw comparisons between countries, seas and policy contexts. European citizens have strong preferences to improve the environmental status of the marine environment by removing and reducing both micro and macro plastic litter and implementing preventive measures favouring a pan-European approach. However, public WTP estimates differ significantly across European countries and seas. We explain why and discuss implications for policymaking.
塑料污染是当今影响海洋环境最具挑战性的问题之一。基于一个涵盖欧洲四个海域和八个欧洲国家的独特数据集，本文补充了与海洋垃圾管理的社会福利效应相关的有限实证证据基础。我们使用离散选择实验来引出公众为按照欧洲海洋战略框架指令的要求在欧洲各海域实现良好环境状态而去除宏观和微观塑料的支付意愿（WTP）。采用共同的估值设计并遵循最佳实践指南，我们对不同国家、海域和政策背景进行了比较。欧洲公民强烈倾向于通过去除和减少微观和宏观塑料垃圾以及实施有利于泛欧方法的预防措施来改善海洋环境状况。然而，欧洲各国和各海域的公众支付意愿估计值存在显著差异。我们解释了原因并讨论了对政策制定的影响。
