Pascal Lamy has made a major break with past WTO positions, and suggested that the WTO should include a chapter on trade and environment. The doctrinal core of his speech seems to be the following:
But it [the Doha Round's promise for the environment] also includes a promise to ensure greater harmony between the WTO and MEAs: a promise to tear down the barriers that stand in the way of trade in clean technologies and services; as well as a promise to reduce the environmentally harmful agricultural subsidies that are leading to overproduction and harmful fisheries subsidies which are encouraging over-fishing and depleting the world's fish stock.
The MEA problem may not be so great after Shrimp-Turtle, and agricultural subsidies is an important part of the trade agenda already--it was earlier called a trade-environment "win-win". Emphasis on freeing trade in clean technologies and services is perfectly consistent with the WTO free trade agenda also. So, this appears to be a speech that looks at areas where there is little conflict between free trade and environmental protection. Of course, the big issue that Lamy does not address is Kyoto and the possibility of a trade response to the U.S. failure to reduce greenhouse gases. This is an area where the goal of internalization of externalities (posited by Lamy in his speech) is inconsistent with free trade.
