Interstate compacts are legally binding agreements that states can enter into to take collective action to solve shared problems or enact a common agenda.6 States enter these compacts for various reasons—to address complex interstate policy issues like cross-border crime, to administer shared resources and boundaries like bodies of water, to establish common standards and guidelines like regulating carbon dioxide emissions, or merely to lower costs by taking advantage of economies of scale. Interstate compacts also allow groups of states to partner with the federal government to address national issues, like emergencies. These compacts give states the flexibility to pilot new solutions and adapt to challenges that emerge over time. They can also help states take advantage of their distinct capacities and build consensus towards greater collaboration.
