Social Norms
Develop your project so that the behavior you are targeting can become a social norm

Facilitate community visibility
Publicize activities and feedback on results of activities
Some activities are already visible: renewable energy system, curbside recycling or compost bins.

Once a ‘norm’ is established, keep it going
If you develop a collection program for items, keep it going

Personal contact: Keep in contact with those exhibiting these norms to reinforce them! Talk with those that are not as well!
