In the absence of international statutes prohibiting nations from causing each other environmental damage, scholars of international environmental law typically focus on trying to identify and clarify norms of "customary international law": that body of commonly accepted—but not formalized—legal principles that is manifest in the behavior of nations toward one another. ███

The pollutants are mentioned as an example of how nations don’t follow the two principles that are purported to be norms of environmental law. The author never claims that debates about customary international law don’t give enough attention to environmental issues.

This is the best answer. The pollutants are mentioned as an example of how nations don’t follow the two principles that are purported to be norms of environmental law. And because the nations don’t follow those principles, they do not meet the requirement that nations actually abide by a principle in order for that principle to be a part of customary international law.
