Trade and Environment: The Evolution from GATT to WTO

Few debates in international politics are as tangled as the one between free trade and environmental protection. On one side is the promise of economic growth through open markets. On the other is the worry that unchecked trade can drain forests, deplete fisheries, and pump carbon into the atmosphere. The story of how the world tried to reconcile these two goals runs through two institutions: the General Agreement on Tariffs and Trade (GATT) and its successor, the World Trade Organization (WTO). Understanding this shift explains a lot about why today’s trade rules look the way they do, and why developing economies remain wary of them.

What GATT was built to do 🔗

GATT came out of the post-war moment when nations wanted to rebuild shattered economies and avoid the trade wars that had deepened the Great Depression. Its roots trace back to the 1944 Bretton Woods Conference, which also produced the International Monetary Fund and the World Bank. Signed in 1947, GATT had one core mission: cut the barriers that countries threw up against each other’s goods, mainly tariffs and quotas.

On that narrow goal, it worked remarkably well. Through eight successive negotiating rounds, average tariffs among major participants fell from roughly 22 percent in 1947 to under 5 percent by the end of the Uruguay Round. Goods flowed more freely than ever before. But notice what is missing from that mandate: the environment.

Why the environment stayed off the table 🔗

GATT was deliberately limited to the traditional tools of economic protection at the border. For its first three decades, questions about whether trade degraded the environment or harmed workers were essentially kept off-stage. Part of the reason was political: negotiators were authorised to bargain over commercial policy, not over the social or ecological side-effects of trade.

This did not mean the issue was invisible. In 1971, GATT set up a Group on Environmental Measures and International Trade, known as the EMIT group, open to all members. The catch was unusual: the group could only meet if a member requested it. As the International Institute for Sustainable Development notes, that request did not come for twenty years. The dominant fear among trade officials at the time was “green protectionism”, the worry that environmental rules might just be disguised barriers to keep foreign goods out.

The turning point on the road to Rio 🔗

The silence finally broke in 1991. Members of the European Free Trade Association asked for the EMIT group to be convened at last, pointing to the upcoming 1992 United Nations Conference on Environment and Development, the famous Earth Summit in Rio de Janeiro. By then, the political climate had changed. Environmental treaties were multiplying, public concern about pollution and biodiversity loss was rising, and it was no longer credible to treat trade and ecology as completely separate worlds.

This shift fed directly into the negotiations that were already reshaping the global trade system. The marathon Uruguay Round, running from 1987 to 1994, was about to transform GATT from a loose agreement into a permanent organisation.

From GATT to WTO: a much wider remit 🔗

The Uruguay Round concluded with the Marrakesh Agreement, which established the WTO on 1 January 1995. The WTO kept GATT’s core principles, tariff reduction, non-discrimination, and a dispute settlement system, but it dramatically expanded the scope of what international trade rules covered.

New territory: services, investment, and intellectual property 🔗

Where GATT dealt almost entirely with trade in goods, the WTO brought in agreements on services (GATS) and on Trade-Related Aspects of Intellectual Property Rights (TRIPS), along with rules touching investment. Just as importantly, the language of the WTO acknowledged something GATT never had. The preamble to the Marrakesh Agreement tied trade to the broader objective of sustainable development, recognising that expanding world trade had to go hand in hand with protecting and preserving the environment.

There was also a quieter but crucial change in how disputes were settled. Under the old GATT, a ruling only became binding if every member, including the loser, agreed to adopt it, which meant any country could block a verdict against itself. The WTO flipped this into a “negative consensus” rule: a ruling is adopted automatically unless every member agrees to reject it. This made environmental cases far harder to bury.

The Committee on Trade and Environment 🔗

The single most visible institutional step was the creation of the Committee on Trade and Environment (CTE) through the 1994 Marrakesh Ministerial Decision. For the first time, a permanent body inside the trade system was tasked with examining the relationship between commerce and the environment.

The CTE has a two-fold mandate: to identify the relationship between trade measures and environmental measures in order to promote sustainable development, and to recommend whether any changes to the trade rules are needed. Crucially, this mandate stretches across goods, services, and intellectual property, building on the work the old EMIT group never quite got around to doing. Over the years its agenda has expanded to cover eco-labelling, fisheries subsidies, climate change, the circular economy, and plastics pollution.

What the CTE cannot do 🔗

It is just as important to understand the committee’s limits. WTO members have been clear that the organisation should not become an environmental agency. The CTE does not set environmental standards, review national priorities, or write global green policy; those tasks remain with national governments and specialised bodies like the UN Environment Programme. The committee is a forum for dialogue, not a regulator. Its job is to make sure trade rules and environmental goals reinforce rather than undermine each other, a balance the WTO calls “mutual supportiveness”.

When trade rules collided with green rules 🔗

The real test of the new system came not in committee rooms but in the dispute settlement process. Two cases shaped the entire debate.

Tuna, dolphins, and turtles 🔗

The first was the tuna-dolphin dispute, handled under the old GATT procedure in the early 1990s. The United States banned tuna imports from Mexico because Mexican fishing methods killed dolphins. The panel ruled against the US, raising a question that still echoes today: can one country use trade restrictions to force another to change how it produces goods, rather than judging the goods themselves?

The more consequential case for our region was the shrimp-turtle dispute, decided by the WTO in 1998. The US banned shrimp imports from countries whose trawlers did not use turtle-excluder devices, and India, Malaysia, Pakistan, and Thailand challenged the measure. The outcome was subtle and significant. The Appellate Body agreed that protecting sea turtles was a legitimate environmental objective. The US lost the case not because it tried to protect the environment, but because it discriminated, giving Caribbean nations technical help and longer transition periods while denying the same to the four Asian complainants. The ruling signalled that environmental measures are permissible under the trade rules, provided they are applied fairly and not as a disguised form of protectionism.

TRIPS, biodiversity, and the developing-country fault line 🔗

If disputes exposed one tension, the TRIPS Agreement exposed another. By setting global minimum standards for patents and other intellectual property, TRIPS became deeply controversial, with the dividing line running largely between developing and developed nations. Many poorer countries are rich in biodiversity and traditional knowledge but lack the capital and laboratories to commercialise it, while the firms that patent these resources are often based in wealthy economies.

This is where the environmental angle sharpens. Critics argue that strong patent rules can slow the transfer of climate-friendly technology to the countries that need it most. There is also the problem of biopiracy, where genetic resources and traditional knowledge are patented abroad without consent or benefit-sharing. Cases involving neem and turmeric became rallying points for this concern.

Where India and the Global South stand 🔗

India has been one of the most active voices on these issues. Alongside Brazil and Peru, it has pushed at the WTO to link the TRIPS Agreement with the Convention on Biological Diversity, demanding that patent applicants disclose the origin of genetic resources to prevent misappropriation. India has also argued consistently for technology transfer, capacity-building, and protection of farmers’ rights. These positions reflect a broader Global South argument: that trade rules written largely by industrialised economies should not lock in environmental and developmental disadvantages for everyone else.

The Doha Round, launched in 2001, was meant to address many of these grievances and marked the first time environmental issues featured explicitly in a multilateral trade negotiation. Yet it has stalled, and the WTO’s dispute settlement system has faced its own paralysis, leaving many of these questions unresolved.

The bigger picture 🔗

The journey from GATT to the WTO is, at heart, a story about scope. GATT treated the environment as a distraction from the real business of lowering tariffs. The WTO, born of a changed world, accepted that trade and ecology are interlinked and built institutions to manage that link. The shrimp-turtle ruling showed the system can accommodate environmental goals; the TRIPS debate shows how much friction remains, especially for developing nations trying to protect their resources and reach their development goals at the same time.

What do you think? Should the WTO go further and actively set environmental standards, or would that overstep the proper role of a trade body? And when a rich country and a poorer one disagree over how to balance trade liberalisation against environmental protection, whose priorities should the global rules reflect?
