To summarize, carbon pricing will always be a regressive tax. I also think that there are a number of practical reasons that carbon pricing will not work as theorized. Because a global program is impractical, leakage is always going to be a problem. All carbon pricing proposals need to address the problem that as carbon emissions go down revenues go down relative to the fact that reductions get more difficult and expensive as control efficiency increases. The academics who support carbon pricing seem to be blissfully unaware of the realities of the energy market that are at odds to their theories. Based on observed results I think that indirect market signals are going to lead to less cost-effective reductions in the time frame necessary for the aggressive reduction rules. To date, carbon pricing for the electric sector only considers generation costs which leads to cost shifting the additional costs to supply electricity when and where it is needed to be covered outside the carbon pricing framework. Finally, supporters under-estimate the very real problems of implementation logistics. My concerns about carbon pricing are supported by the RAP study.
