In order to make significant progress towards SCP, governments need to understand how its sector policies and fiscal system influence patterns of production and consumption, and to make revisions where there are conflicts with sustainability objectives. Clear visions need to be established and communicated, consistent and well-coordinated policies, including sector policies as well as dedicated SCP policies, should create incentives and legal obligations towards that vision. This requires leadership from the highest political level and coordinated action by the governmental departments concerned. For example, a manufacturer that is just about to renew machinery is more flexible than one where a large investment has just been made.
