Comhar, the Irish National Sustainability Council, has contracted AEA Energy and Environment, a major British consultancy, to analyse Feasta’s Cap and Share concept as a tool to control Ireland’s road transport emissions. The policy analysis part of the report should be completed by the end of February and, if the verdict is favourable, another consultancy, Cambridge Econometrics, will be given a contract to use its E3ME model to explore the effects that this use of C&S would have on the Irish economy in comparison with using a carbon tax or fuel excise duty to achieve the same result. Both studies are to be completed by July so that, if the overall conclusions are positive, the government has the option if introducing C&S in its budget in December 2008.
