List of environmental lawsuits that concern the well-being of an environmental asset, like water or air, or lawsuits with environmental relevance, in which a non-environmental entity was in a dispute that had relevance for a specific environmental asset. This list of environmental law cases spans several centuries and lawsuits all over the world. The most popular common subjects of eco lawsuits include water, wildlife, and land pollution, protection, and access rights. Environmental laws can be complicated as environmental assets can impact more than just the jurisdictions in which they lay. Water, oil, air, and forest and coastlands are frequently in dispute as private citizens, local communities, special interest groups, and the federal government debate how to treat them.
