As a free-market environmentalist, Paul sees polluters as aggressors who should not be granted immunity from prosecution or otherwise insulated from accountability. Paul argues that enforcing private property rights through tort law would hold people and corporations accountable, and would increase the cost of polluting activities—thus decreasing pollution. He claims that environmental protection has failed due to lack of respect for private property:
The environment is better protected under private property rights ... We as property owners can't violate our neighbors' property. We can't pollute their air or their water. We can't dump our garbage on their property ... Too often, conservatives and liberals fall short on defending environmental concerns, and they resort to saying, "Well, let's turn it over to the EPA. The EPA will take care of us ... We can divvy up the permits that allow you to pollute." So I don't particularly like that method.
He believes that environmental legislation, such as emissions standards, should be handled between the states or regions concerned. "The people of Texas do not need federal regulators determining our air standards."
