The UN Climate Change Conference begins in Durban, South Africa, on the 28th November. One of its primary aims is to reach agreement on ways to reduce carbon emissions. Good policy is required to achieve reductions efficiently, including a consistent (preferably global) carbon price. However, a consistent price does not currently exist. Within the UK, there are a myriad of policies in place which create substantial divergences in effective carbon prices. We have some way to go to get the basics right for an efficient national policy; the global challenges will be much greater.
