I came across this old NY Times article on nudging. It gives a great example of an innovative but quite simple measure the British Government took to get people to insulate their roofs: they offered a subsidized (but still paying) cleaning and moving service for people's attics. Their presumption was that people pile up all their mess there (as I do too, I must admit), which creates an substantial obstacle to having roof insulation installed. It seemed to work back then, because 5 times more people applied for subsidies. Does anyone have experience with these kind of measures and do you feel they could work in your community?
