This paper examines protectionist trade policies and their potential benefits for domestic industries, with a particular focus on environmental justifications. It outlines common protectionist tools — including subsidies, government procurement restrictions, and tariffs — using the U.S. agricultural and steel industries as examples. The paper then argues in favor of protectionism on environmental grounds, contending that unequal regulatory burdens between nations, such as differing carbon footprints in steel production and inconsistent environmental standards, distort fair competition. It also discusses the limitations of the WTO's National Treatment principle and calls for the development of standardized environmental performance indicators to support equitable, ecologically informed trade policy.
Protectionist policies are policies aimed at supporting a domestic industry against international competitors. These policies can take a range of different forms in their implementation. For example, the U.S. agricultural industry is heavily subsidized, allowing domestic farmers to sell their crops at a price level far below what the market price would otherwise be. This represents a form of indirect subsidy, as opposed to a direct market intervention such as a tax on foreign goods. Another way governments can apply protectionist policies is through targeted government spending.
One example can be seen in the U.S. steel industry, which can be protected by the government procuring steel for public works projects exclusively from domestic steel companies. When the government places such buying restrictions on its demand for steel, it artificially influences market demand through its purchasing activities. The government can justify this intervention on the grounds that the U.S. steel industry is a "strategic" industry vital to the national interest — for instance, a well-developed domestic steel industry would be a significant asset if the U.S. were engaged in a major war.
Such interventions can also be justified on other grounds. One example involves safety or environmental interests. A government may wish to restrict imports of medical or edible goods from a country that lacks significant safety regulations, in order to protect its population from potentially unsafe products. Environmental objectives can be cited in similar reasoning. As noted in congressional testimony in March 2009, United Steelworkers president Leo Gerard explained how unrestricted trade in steel would both ship jobs abroad and worsen global pollution: "Ton for ton," he said, "Chinese steel leaves a carbon footprint three times as large as American steel" (Are Protectionist Policies Beneficial to Business?).
Although a strong case can be made that free trade policies spur innovation through greater levels of competition, the factors of production are not necessarily equal throughout the world. Firms operating in the United States must abide by numerous regulations governing production — imposed by labor unions, minimum wage laws, the EPA, and others. Firms in China and India do not operate under such restrictions and therefore already hold an advantageous position in many industries. A pro-protectionism position holds that the government can play a vital role in ensuring that the terms of competition are fair and equitable in key industries, especially with regard to how those industries treat the environment.
