In the drive to tackle climate change, carbon trading has become the policy instrument of choice among governments. It is also a central element of the UNFCCC’s Kyoto Protocol. National or regional carbon trading schemes are now operational in Europe, the USA, New Zealand and elsewhere.

Unfortunately the subject is characterised by jargon, abstract concepts, mathematical formulae and technical detail, making it hard for most people to understand its implications and assess its merits or otherwise. This guide attempts to unravel some of this complexity.
