At the Uruguay Round of the WTO a preamble was established in reference to WTO Agreements for the protection of the environment. At this same round members agreed to the establishment of a Committee on Trade and Environment. However it is important to note that the WTO does not set rules relating to environmental issues. It only relates to trade affiliated to environmental issues. Also, the WTO supports organisations protecting the environment and tries to co-operate with member organisations in terms of trade liberalisation and environmental issues. Thus the WTO addresses trade issues impacting on the environment.
