The consumption of goods and services can be a driver of environmental and social impacts around the world. Understanding the role that the different levels of government can play in incentivising sustainable consumption is therefore critical. Using systematic review techniques, this paper reviews the latest evidence on the importance, effectiveness, successes and failures of local government in advancing sustainable consumption. We find that there is little focus on sustainable consumption in its entirety or whether it is being achieved at the local government level. Important consumption categories like food, procurement, water, waste prevention, clothing, other consumables or services are understudied. Evaluation of the outcome of sustainable consumption interventions was limited, and the assessment that was completed gave mixed results. The most popular policy instruments were of the less coercive administrative and informative type. Multiple barriers to the success of an intervention were identified, the top ones being funding; staff capacity, knowledge or data; lack of flexibility and lock-in to the status quo; lack of guidance or political will; administrative burdens; and lack of regulatory powers or tools. Sustainable consumption interventions by local government were most effective when they had strong leadership, good stakeholder engagement, participatory approaches and extensive consultations.
