The Marine Strategy Framework Directive (2008/56/EC) aims to achieve Good Environmental Status of the European Union's marine waters for which the EU Member States are preparing Programmes of Measures (PoMs) to coordinate policies and improve the marine environmental status. These Programmes are revised every six years, yet there is currently no comprehensive and robust methodology to assess the effectiveness of PoMs and their contribution to reaching Good Environmental Status. This paper presents a new and concrete methodology combining policy, socio-economical, and environmental aspects, relying on available monitoring data, official reporting, and expert judgement to yield easily comparable numerical results. The utility of this methodology is also demonstrated on a series of hypothethical measures under descriptors 1 (Biological diversity), 3 (Commerical fisheries stocks), 6 (Seafloor integrity), and 10 (Marine litter). The demonstration shows how the method can be used by policy and decision-makers across the EU, as well as a variety of expert and non-governmental actors to evaluate the progress and potential of individual PoMs on national and (sub)regional levels. Therefore, the method could pave the way to more coherent, coordinated and effective measures to protect EU seas.

海洋战略框架指令 (2008/56/EC) 旨在实现欧盟海洋水域的良好环境状况，欧盟成员国正在为此制定措施计划 (PoM)，以协调政策并改善海洋环境状况。这些计划每六年修订一次，但目前还没有全面和稳健的方法来评估 PoM 的有效性及其对实现良好环境状态的贡献。本文提出了一种结合政策、社会经济和环境方面的新的具体方法，依靠可用的监测数据、官方报告和专家判断来产生易于比较的数值结果。该方法的实用性还体现在描述词 1（生物多样性）下的一系列假设测量中，3（商业渔业种群）、6（海底完整性）和 10（海洋垃圾）。该演示展示了整个欧盟的政策制定者和决策者以及各种专家和非政府行为者如何使用该方法来评估国家和（次）区域层面单个 PoM 的进展和潜力。因此，该方法可以为采取更加一致、协调和有效的措施来保护欧盟海域铺平道路。
