Although WTO has no definite accord dealing with environmental problems, the WTO agreements confirm governments’ right to protect the environment which enable the provided certain conditions to be met. As the result of negotiation in the Uruguay Round in 1994, trade ministers of participating states determined to start a comprehensive work programmed on trade and environment in the WTO, they created the Trade and Environment Committee. The agreement that established WTO in the 1994 recognized “the objective of sustainable development, seeking both to protect and preserve the environment.” The committee takes a broad-based responsibility covering all areas of multilateral trading system- goods, services, and intellectual property. The roles of the committee are to study the relationship between trade and environment, and to make recommendations about any changes over trade agreements. As the WTO is not an environmental agency, its work is based on two important principles. First, the committee can only study the problems which emerge when environmental policies make an enormous impact on trade. Second, if the committee does identify problems, its solutions must continue to uphold the principles of the WTO trading system- market liberal and non-discrimination.There are three remarkable achievement of the WTO rules. First, under multilateral environmental agreements, no specific provisions have been challenged in the WTO, meaning that the environmental agreements may be the indispensable and effective ways to address environmental issues. Second, developing countries have more rights to participate in standard-setting, therefore allowing them to gain access to international markets. Lastly, the WTO has not given rights to environmental labelling to provide full information to consumers. Furthermore, according to official website of the WTO, the Dispute Settlement Body of the WTO has made some decisions which tended towards environmental interests. One of the cases is the ‘shrimp-turtle’ case brought by India, Pakistan, Malaysia, and Thailand in order to against the United States. The official title of the case is ‘United States — Import Prohibition of Certain Shrimp and Shrimp Products.’ The panel upheld the US prohibition on the imports of shrimp harvested in way that affected sea turtles. The panel also encouraged member states to protect the sea turtles, which resulted in the MoU on the Conservation and Management of Marine Turtles and Their Habitats in the Indian Ocean.
