The document discusses approaches to promoting sustainable behavior change through community-based social marketing. It describes two general approaches - focusing on a specific behavior versus promoting general environmental activity and behavior change.

Research suggests using a combination of strategies framed in a positive manner to build people's competence and sense that their actions can make a difference.
