（b）make appropriate recommendations on whether any modifications of the provisions of the multilateral trading system are required, compatible with the open, equitable and non-discriminatory nature of the system.
部长们决定把上述宽泛的授权限定在10项具体工作的议程，并将该议程作为其讨论的框架。2001年多哈部长级会议后，成员方要求委员会主要集中考虑三个问题：（1）WTO与多边环境协定的关系；（2）多边环境协定的秘书与WTO信息交流的程序，以及在WTO会议中承认多边环境协定观察员地位的标准；（3）减少或消除环保货物和服务贸易的壁垒。此外，委员会在履行其工作计划时还应格外注意以下三方面内容：（1）环境措施对市场准入的影响，以及消除贸易冲击对环境的益处；（2）TRIPS协定的相关条款；（3）为环境保护目的的标识要求。
在10项授权范围事项中，第1项、第5项和第10项，即多边贸易体制规则与多边环境协定中的贸易措施的关系及其争端解决机制的关系，WTO与政府间和非政府组织的关系，目前正处于谈判中。第3项、第6项和第8项被列为重点问题。
