There is an inherent conflict between free trade and environmental protection through market mechanisms. This conflict resides in the contradictory objectives of internalising the costs of environmental externalities and the pursuit of comparative advantage within free trade.
Economic externalities are created where the activity of one person or entity affects the welfare of other persons or entities who have no direct means of control over those activities, and the costs of this interference are not reflected in the price of the good that creates this intrusion.[1] In essence this means that the effect the product had on the third party goes unnoticed. The inequitable result of this is that the person or entity that causes the externality is receiving a public (or “neighbourhood”) subsidy for the product. Thus, the price of the product does not reflect its true cost.[2]
This problem has traditionally received only peripheral attention. However, in the area of environmental policy, these externalities have become so obvious with many international environmental problems that they can no longer be ignored.[3]
The solution to the problem is believed to lie in making the polluter internalise the cost of the externalities. Internalisation creates an incentive to reduce the activity that produces the external cost, as the prices paid for the item in question rise to reflect the full value of all the sacrifices made to produce it.[4] This argument has now been extended to cover environmental externalities. For example, Principle 16 of the 1992 Rio Declaration on the Environment and Development states:
National authorities should endeavour to promote the internalisation of environmental costs and the use of economic instruments, taking into account the approach that the polluter should, in principle, bear the cost of pollution, with due regard to public interest.[5]
In response to the problem of externalities, new methods have been devised to correct the market failure.[6] The primary method is through taxation, which is a popular idea in both Green theory[7] and contemporary political debate.[8]
This idea of taxes to counter environmental externalities is typically ascribed to Arthur Pigou. He devised a series of taxes and subsidies to account for the social costs which were not incorporated in private decision-making.[9] Crudely, a tax is placed on polluters to bring their cost function into line with what it would have been had they faced the true social cost of their production. Thus, environmental taxes are a way of incorporating the indirect costs into the economy, correcting the shortcoming of the market.[10] This ideal is also broadly consistent with the Polluter Pays Principle. This is a guiding principle of the OECD’s environmental policy, which recognises:
when the costs of [environmental] deterioration are not adequately taken into account in the price system, the market fails to reflect the scarcity of such resources ... the costs of these measures should be reflected in the costs of goods and services which cause pollution and/or consumption.[11]
This concept is intuitively attractive, as it embodies the idea that environmental externalities should be internalised by those who cause them.[12]
Adam Smith opened the door for international economic integration. His thesis of laissez-faire was embodied in his influential work The Wealth of Nations.[13] Smith disagreed with domestic protectionist ideals, and sought to end mercantile institutions by moving towards the “free laws of commerce” in an international setting which would allow the free market system and societies within them to find their true balance, and thus create economic efficiency via specialisation, which would benefit all of those involved.[14] David Ricardo elaborated upon this idea with his thesis of comparative advantage. He postulated that:
Under a system of perfectly free commerce, each country naturally devotes its capital and labour to such employments as are most beneficial to each. This pursuit of individual advantage is admirably connected with the universal good of the whole.[15]
The idea that all benefit from free trade has reappeared in the international environmental arena. For example, Section 2.5 of Agenda 21 states:
An open, equitable, secure, non-discriminatory and predictable multilateral trading system that is consistent with the goals of sustainable development and leads to the optimal distribution of global production in accordance with comparative advantage is of benefit to all trading parties.[16]
The use of comparative advantage is believed to be in accordance with sustainable development. This is because free trade is expected to improve the environment through international competition which is alleged to be environmentally beneficial because of the efficient use of resources, higher productivity and increasingly efficient technologies. These factors are all deemed necessary for sustainable development.[17]
In this context, the ideal of comparative advantage involves an important assumption, namely, that the environment can be used to achieve comparative advantage. In essence, this means that low environmental standards are seen as part and parcel of a country’s comparative advantage to be exploited through trade.[18] Thus, as the Secretariat of the GATT stated:
in principle there is no difference between the competitiveness implications relating to different environmental standards and the competitiveness consequences of many other policy differences between countries - tax, immigration and education policies for instance.[19]
Thus, as the OECD suggested earlier, “[d]ifferent national environmental policies, for example, with regard to the tolerable amount of pollution, are justified”.[20] Consequently, the international trading system ought not to apply to redress or harmonise the different environmental approaches that different countries are willing to tolerate.[21] Therefore, trade advantages gained by countries willing to accept lower environmental standards are treated as part of the “efficient reallocation of production internationally”.[22] Under this theory, Southern countries should take advantage of the fact that their environmental standards are lower than in Northern countries, as a means to attract more investment.[23]
A conflict arises between internalising environmental externalities and comparative advantage when one nation chooses to internalise environmental costs, through for example the creation of taxes, whereas another does not, and, in contrast, actively externalises environmental costs in an attempt to obtain comparative advantage.[24] In such settings, the externalising nation will be actively exploiting a malfunctioning market place, as it is in effect claiming an environmental subsidy by not insisting that the correct price, that takes into account the externality considerations, be paid.[25]
This problem comes to a head when two nations allow their products to compete in an international open economy. Indeed, as the Business Council for Sustainable Development recognised:
The question remains - and to which we have no convincing answer nor indeed know of one - is how can a ... nation charge a price for exports that reflects their environmental costs, and compete against other nations willing to absorb such costs for short term profits?[26]
The difficulty is that there is an imbalance in price, as any product that does not incorporate the costs of externalities, as opposed to a product that does, will be cheaper. This means that a country that chooses to internalise its environmental costs will be at an economic disadvantage in an open market place.[27]
In such a setting, the most obvious solution, if the objective is to internalise the costs of environmental externalities, is to be found in unilateral or regional actions between like-minded countries in an effort to create level economic playing fields.[28] To do this, it is primarily necessary to impose restrictions upon products which do not incorporate the costs of environmental externalities in the same manner that a domestic producer may.
Despite the possibility of averting the conflict through unilateral actions which may create level economic playing fields by making all competitors internalise environmental costs, a further impediment stands in the way. This is the prima facie rejection of unilateral actions in international trade policy when dealing with environmental concerns. In such settings the emphasis is that all actions on environmental issues which could affect differing nations’ exports should be based upon international consensus. This belief stems from an established fear that individual domestic environmental protection justifications which are unilaterally introduced into free trade arenas could act as potential barriers to products that are produced in different, and in this instance, environmentally unfriendly ways. [29] This fear has been particularly acute with Southern countries.[30] Consequently, they are strong advocates of “environmentally unhindered” free trade.[31]
This idea was forcefully brought out at the 1992 United Nations Conference on Environment and Development (UNCED), where the use of unilateral trade distorting measures designed to protect the environment was explicitly and repeatedly rejected.[32]
This outlook reflects the 1991 ruling by a GATT panel of the “Mexican Tuna” issue, where the United States unilaterally restricted the importation of tuna which was caught by Mexican fishermen using fishing methods that are detrimental to dolphins.[33] There it was held that environmental protection considerations extending beyond a country’s jurisdiction could not be used to restrict imports. This would be acceptable only if action was required by international law, such as the Convention on International Trade in Endangered Species of Flora and Fauna[34] or the Montreal Protocol on Substances that Deplete the Ozone Layer,[35] but not if it was required only by domestic law.[36]
Thus, the application of tariffs to the products of other countries which do not attempt to incorporate the costs of environmental externalities may be struck down if there is no pre-existing international agreement dictating the needs for such policies.
Comparative advantage, which works upon externalising environmental costs, is not only an oversight in pricing, it also provides a subsidy by discounting the cost of environmental destruction. However, the Subsidies Code of GATT[37] encourages parties to eliminate subsidies as a form of domestic trade regulation because they are trade distorting.[38] Nevertheless, despite this general appearance of GATT and its inherent dislike for subsidies, certain subsidies continue to be tolerated within free trade agreements (such as for defence industries.)[39]
This is a political choice. If this type of trade distorting subsidy is accepted, there should be an equal or more compelling reason for the elimination of environmental subsidies, through externalities, which openly distort free trade. Yet ironically the definition of subsidy is often stated in very broad terms, and environmental protection, not environmental destruction, can be classified as such.[40] Additionally, the preference in times of conflict is for the capture of comparative advantage, rather than the internalisation of environmental costs. For example, point five of the OECD’s Guiding Principles on the Environment notes that the correct pricing of the environment:
Should be an objective of member countries ... provided that they do not lead to significant distortions in international trade and investment.[41]
This perspective is in accordance with the view that a willingness to destroy the environment should be openly tolerated to achieve comparative advantage. However, this comparative advantage works upon a manipulation of market pricing. Hence the contradiction of free trade in a manipulated market.
There are three possible responses to this problem. One, the nations that internalise environmental costs protect their markets and risk retaliatory measures in the international trade arena. Two, comparative advantage is retained in its classical sense, and environmental costs are willingly incurred and the environment is increasingly destroyed in a race to the bottom for environmental concerns, in the absence of international agreements. Finally, environmental costs are internalised and the market is corrected, consequently increasing environmental protection, and comparative advantage is rightfully orientated to mean free trade, in a free market, in a more sustainable manner.[42]

[31] This position can be traced back to the 1971 Founex report which stated some of the fears Southern countries had of international environmental regimes: (1) Fear that the developed nations will create rigorous environmental standards for products traded internationally and generate “neo-protectionism” excluding non-conforming goods from poor lands. (2) Fear that the developed lands will unilaterally dictate environmental standards to the developing lands without considering how to relate those standards to the conditions of the developing lands (Founex Report, Environment and Development (1971), reprinted as Annex 1 to UN Doc A/CONF 48/10, December 10, 1971, or International Conciliation No 586, 1972). These fears partly found their way into Recommendation 103 of the 1972 Stockholm Conference on the Human Environment, which states: “All countries present at the Conference agree not to invoke environmental concerns as a pretext for discriminatory trade policies or for reducing access to markets, and recognise further that the burdens of the environmental policies of industrialised countries should not be transferred either directly or indirectly to the developing countries” (UN Doc A/Conf 48/14, 1972). This ideal was earlier recognised in principle 4 (e) of the UNGA Res 2849 (XXVI) Dec 7, 1970 on Development and the Environment which suggested that the 1972 Stockhom Conference should “avoid any adverse effects of environmental pricing on the economies of developing countries, including [through] international trade”.

[42] Note that certain important commentators such as David Pearce (supra note 40, at 299-300) suggest that it is better to adopt “corrective policies” such as international financial assistance and technology transfers to Southern countries, rather than distort international trade in an attempt to incorporate environmental externalities. The problem with this is that while it may encourage Southern exporters to adopt better environmental policies it neither economically protects countries that do incorporate the costs of environmental externalities, nor encourages Southern countries to work directly towards incorporating environmental costs. A better approach would be to protect the entities which internalise environmental costs, and redistribute a portion of the increased tariffs that are incurred by non-internalising countries (depending upon their economic position) to parties which do attempt to internalise their costs.
