It has been evident for some time that trade policy and environmental policy cannot long pretend to ignore each other’s existence. Conceptually, each is an integral element of sustainable development; which, ostensibly, is a stated goal of both. Practically, they already cast long shadows on each other and the actual implementation of each influences, and is influenced by, the other. After years of tortured public discussion on the subject, the Fourth Ministerial Meeting of the World Trade Organization (WTO), held in Doha, Qatar, finally placed a limited set of trade and environment issues on the negotiating agenda of the multilateral trading system. The World Summit on Sustainable Development (WSSD) held in Johannesburg, South Africa, reaffirmed the need to establish more coherence between trade policy and environmental policy. Limited as these incursions might be, they suggest a trend and a tendency that is likely to be irreversible. It has been argued that within the context of the WTO, the question is no longer whether trade and environmental policy are going to be linked, but how. The answer, of course, is far from clear because a) the Doha mandate on trade and environment was left purposely vague; b) the issue is new to multilateral trade negotiations and its many implications and manifestations have not yet been fully explored; and c) because of that, parties have yet to fully develop and firm their positions on this subject as they have on many others. For all of these reasons, there is an opportunity for all parties to shape the agenda on future trade and environment negotiations in rather more profound ways than might be possible on many other issues. This opportunity is particularly pertinent to the developing countries of the South because they, for most part, have been generally suspicious of environmental issues seeping into trade deliberations and accepted the Doha mandate for trade and environmental negotiations rather hesitantly, if not grudgingly. The purpose of this paper is to better understand Southern concerns about the forthcoming trade and environment negotiations and to explore how an emergent Southern agenda might take shape. The analysis presented here derives directly from a review of Southern views on trade and environment issues compiled as part of an ICTSD/IISD/RING research project on the ‘Southern Agenda for Trade and Environment.’ While a budding literature on the subject does exist, this project was an early attempt to systematically collect and analyze the views of developing country delegates themselves. Methodologically, two distinct ‘data’ sets were constructed. The first compiles together the various formal interventions and proposals made by developing countries within the WTO; most particularly within the WTO Committee on Trade and Environment (CTE). The second data set of Southern views on environment and development is drawn from several months of consultations and discussions with developing country negotiators in Geneva and Brussels. These small group discussions sought to elicit a first-hand articulation of Southern concerns and interests in relation to trade and environment issues from developing country delegates, especially in terms of the post-Doha negotiation agenda. This paper presents a review and synthesis of the learning from these two data sets of Southern views on trade and environment. The research concludes that although the developing countries are likely to adopt a conservative strategy in negotiating the environment and trade aspects of the Doha workplan, this is to be expected. This is because developing countries a) had initially resisted these provisions, b) are the historically weaker parties and therefore prone to risk-minimizing strategies, and c) the newness of this issue for trade negotiations coupled with the resource and time strains on Southern delegations will itself limit the scope of innovation by any party. The previous section has outlined three key ingredients of the South’s post-Doha concerns that are likely to influence the defensive aspects of the South’s negotiation position between now, and January 2005. However, the more important conclusion relates to the emerging willingness within the developing countries to begin engaging the trade and environment agenda and to possibly re-craft it within the framework of sustainable development. This is neither going to be easy, nor automatic. While it is to the obvious benefit of the South (and many other parties) for the developing countries to adopt a proactive strategy, doing so will require much effort from the South itself and a supporting environment from other actors interested in a furthering the links between trade, environment and sustainable development. What can the South do itself to move from a reactive agenda defined by its apprehensions about trade and environment to a proactive agenda that seeks the opportunities to be realized by defining sustainable development as the goal of international trade? How can other international actors assist? The paper will outline four key steps in this direction. [ABSTRACT FROM AUTHOR]
