International Environmental Agreements and Trade
Global environment is subject to two adverse externalities. Transnational environmental degradation, a type of negative externality, imposes certain costs not only on the originating country but also on the other countries (ozone-layer depletion is a good example of this). On the other hand, policies aimed to tackle transnational environmental degradation, involve positive externality from which all countries benefit regardless of their taking action. As a result, countries leave it to others to take pro-environmental actions, and this may result in under-production (if not zero) of environmental good. Thus, as in the public good case, global environmental protection is subject to free-riding. In this chapter, we will present the interactions between trade and environment in the context of international environmental agreements with special attention to international trade regime, trade-environment disputes, and free-riding incentives on global environmental protection.

- 1.In an earlier literature, there has been put some doubt on the importance and the existence of the free rider problem. Explicitly, we can cite Bohm (1972), Sweeney (1973), and Smith (1979), who designed experiments which resulted in negligible free-riding when the agents had strong incentives to free ride. Nevertheless, Kim and Walker (1984) suggested that there were some’ invalidating factors’ in these previous experiments and by removing these factors in their experiment, they found out that, in fact, free-riding was substantial.Google Scholar
- 2.First principle requires that like products from different countries must be treated equally; second one applies the same rule to imported products versus domestic products; third one mandates that all non-tariff barriers, quotas, bans, etc., be converted to tariffs; and the last principle requires parties to try to settle their trade disputes through consultation and negotiation. See, for example, Esty (1994).Google Scholar

- 7.Note that this enforcement policy through trade barriers could be challenged under GATT regulations by non-member countries; however, most members of the GATT are also members of the Montreal Protocol, so such challenges need not diminish the effectiveness of this enforcement policy. Trade works for environment here.Google Scholar

- 10.We will only summarize the eight out of the twelve cases mentioned. The distinction is based on whether the disputes have been based on articles XX-b and XX-g, which provide explicit provisions for environmental protection.
