The document discusses a project between Camden Council, University of Oxford, and University College London to encourage more sustainable behaviors and reduce printing. The project involved collecting robust printing data to understand behaviors and inform interventions. A similar approach to a previous heat metering project was used. The goals were to reduce printing to save paper and money, and allow for behavioral analysis. The project saw a 15% decrease in printing, equivalent to £86,000 yearly savings, and provided insights into top-down and bottom-up approaches to changing behaviors.
