Preemption Map

In addition to the six health and safety movements documented on this map, federal and state preemption have been used to undermine dozens of other grassroots movements on issues ranging from fracking to fire prevention. Preemption is usually promoted by an industry to stop progress in public health because industry lobbyists have more influence in Washington, DC and the state capitols than at the community level.
