This article explores how environmental regulation may be improved through the use of community-based social marketing techniques. While regulation is an important tool of sustainability policy, it works upon a limited range of behavioural ‘triggers’. It focuses upon fear of penalty or desires for compliance, but individual behaviour is also affected by beliefs and values, and by perceived opportunities for greater satisfaction. It is argued that more effective environmental laws may be achieved using strategies that integrate regulation with community-based social marketing. Case studies where community-based social marketing techniques have been successfully used are examined, and methods for employing community-based social marketing tools to support environmental regulation are proposed.
