（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.
部長們決定把上述寬泛的授權限定在10項具體工作的議程，並將該議程作為其討論的框架。2001年多哈部長級會議後，成員方要求委員會主要集中考慮三個問題：（1）WTO與多邊環境協定的關係；（2）多邊環境協定的秘書與WTO信息交流的程序，以及在WTO會議中承認多邊環境協定觀察員地位的標準；（3）減少或消除環保貨物和服務貿易的壁壘。此外，委員會在履行其工作計劃時還應格外注意以下三方麵內容：（1）環境措施對市場準入的影響，以及消除貿易衝擊對環境的益處；（2）TRIPS協定的相關條款；（3）為環境保護目的的標識要求。
在10項授權範圍事項中，第1項、第5項和第10項，即多邊貿易體製規則與多邊環境協定中的貿易措施的關係及其爭端解決機製的關係，WTO與政府間和非政府組織的關係，目前正處於談判中。第3項、第6項和第8項被列為重點問題。
