Abstract
This study examined the effects of three community interventions that rely on socially mediated consequences, rather than financial incentives, to promote consumer recycling. Households in the commitment-only group signed a letter making a public commitment to recycle and giving permission to publish their names in a local newspaper. The feedback-only group received weekly feedback on pounds of recyclable paper generated by their group. A combined-intervention group received a combination of the two previous interventions. Relative to baseline, the feedback-only and the combined-intervention groups increased the weight of recyclable paper by 25.47% and 40.00%, respectively. In contrast, neither the commitment-only group nor a no-intervention control group showed substantial changes over the same period. The implications of these interventions for developing community-wide recycling programs are discussed.
