The main types of instruments available to policy makers are economic instruments, regulations, information-based approaches, including environmental labelling, voluntary approaches, and public financial support. For instance, the number of countries reporting the use of economic instruments such as landfill taxes increased significantly in the past 15 years and this has led to the diversion of waste, away from landfills into material and energy recovery. Efforts upstream of end-of-life management have been more modest: an example is waste prevention, which includes policies that encourage greener product designs and measures to change consumer behaviour.
