What kinds of feedback mechanisms work best for a community-wide carbon reduction campaign for (1) the households involved, and (2) the community as a whole? Some of the carbon calculators and social networking sites show individuals how close they are to achieving their stated goals as they check off each action taken. This is also the LCD approach. Aggregated to the community level, David's "Cool Communities" program suggests a website that shows progress over time as households take the actions. See: "Momentum for the campaign is built through a visible feedback loop that shows the individual drops filling the bucket. Results are reported on the robust, interactive, and graphically compelling website. Reported results include number of partner organizations, teams formed per partner, cumulative CO2 savings per partner, average CO2 reduction per household, and cumulative results against quarterly and final community goals."

1. Given that the LCD actions are self-reported, will this kind of feedback be taken seriously? What kinds of political problems might we encounter from people interested in dismissing or debunking the campaign?

2. What kinds of feedback are most effective in changing and sustaining household behavior over time?
