Report that makes the economic case for the establishment of a US carbon market by Washington DC policymakers – one that could be business-friendly, cost-effective and flexible. The author looks at other US emissions trading programs (such as SO2 and NOX) to illustrate the proven effectiveness of market based schemes for reducing undesirable emissions in an economically efficient manner. The nascent carbon market is evaluated and the author concludes with a compelling argument as to why the US needs a carbon market whether or not it decides to join Kyoto.
