Over the past three decades, decoupling has emerged as a regulatory strategy for promoting conservation, especially in the energy sector. Decoupling refers to the separation of a firm’s revenues from the volume of its product consumed. Decoupling allows companies to pursue resource efficiency free from financial risk. Similarly, when private firms provide public services, they separate public policies from their political costs. This political decoupling allows governments to pursue controversial policies while avoiding their attendant political risks. Applied to environmental policy, this theory implies that unpopular conservation policies are more likely to be adopted and succeed when implemented through private firms. Our empirical subjects are California water utilities and their responses to that state’s 2014–2017 drought. Analysis shows that, compared with those served by municipal utilities, communities served by private utilities adopted more aggressive conservation measures, were more likely to meet state conservation standards, and conserved more water.
