A global benchmarking of policy instruments for effective climate change mitigation demonstrates the need for a mix of policy measures. The optimal policy package is characterised by the complementarity of its policy components, and the recognition of context: the appropriateness of the mix of measures varies from country to country depending on unique sets of climate change challenges as well as other national objectives.
At present, South Africa is considering a number of policy options for climate mitigation: a carbon tax, desired emissions reductions outcomes, and required energy management plans. To determine the optimal policy package, an assessment of the range of policy instruments is needed, particularly in understanding how these instruments can be used together and in which cases they are redundant or suboptimal and burdensome.
This policy brief cautions against the development of a single policy instrument in isolation and proposes a better understanding of policy complementarity and alignment.
