Unfortunately, I am almost completely incapable of answering it.As Robin Harper will know, the sustainability network is carrying out substantial work in benchmarking the current energy-efficiency policies and investments of different councils and public organisations, and finding out how we can track the degree to which such investments pay off. Because of the behavioural and cultural factors that are involved, the network is also thinking about programmes that will not only put in place relevant infrastructure, but will alter attitudes to energy utilisation in public services.
