I have a reasonable idea at this stage when the Minister is serious about something, and I am sure he is not serious about carbon taxes. This question arose approximately three years ago as part of the climate change strategy. The Minister paid lip service to it at the time. He announced last year that he would introduce these taxes this year. The tax strategy group considered it at some length and produced page after page of objections from various Departments. The Minister announced on budget day that he intended to introduce carbon based taxes from the end of next year, which I do not believe.
