You will have to forgive me for first mentioning that yesterday I went to a meeting on climate change in the House of Lords chaired by none other than Nigella’s Dad. We even spoke a few words to each other but I doubt he went home and blogged about meeting me.
But it was a serious meeting with a serious proposal that the Coalition should look at seriously given that we already have a carbon tax in place which, given the future state of the Senate, may not be removable in the first instance.
There was a presentation on what the speaker, Ross McKintrick, described as a “Temperature Index Tax”. You start with a carbon tax put in at a very low rate and then you index the tax based on movements in some particular temperature, with the proposal based on the recorded temperatures in the tropical troposphere since they are apparently especially responsive to changing concentrations of CO2. The size of the tax then depends on actual outcomes which could even go down depending on what happened to the actual temperature. There were then three additional features:
1) It is an “instead of” tax and not an “addition to” tax. For carbon taxes to be effective, there must be no other carbon abatement programs. The rest should then be completely repealed and no new programs added in.
2) The tax must be revenue neutral. The revenue raised cannot be used for any other purpose except lowering other taxes. Otherwise the tax becomes a source of regulatory inefficiency.
3) It must always be understood that the carbon tax as described is a price instrument, not a quantity instrument. Major issues if the attempt is made to use it for both.
Since Nigel Lawson has about as much belief in AGW as I do, the aim is to find some mechanism that will allow an each way bet on what temperatures will do. If you think they will go up a lot you get your abatement taxes and everyone is in agreement. If they don’t go up, then no one has to do anything and everyone is content that a contingency plan has been put in place. Various forms of futures markets also become operable which allow for hedging. The suggestion that the superannuation of global warmists be related to the tax revenues raised has an appeal but that was an idea raised from the floor and not part of the proposal.
I’m afraid I cannot link to the report on the primitive machine I am using but I suspect that if you go to http://www.thegwpf.com you will find the paper there under the title, “An Evidence-Based Approach to Pricing CO2 Emissions”.
