It provides a general overview of policy approaches and tools of particular relevance to SCP. It emphasises how policy tools in many cases become more effective when introduced as well designed policy-packages that provide support for more sustainable practices while at the same time discouraging less sustainable products, services and behaviours. This chapter provides an overview of the policy cycle (Dovers 2005) in an idealised way. In practice, the sequencing may look quite different, but all elements are of equal importance if SCP policy objectives are to be achieved.
