Climate Change Bill [HL]

I say at the outset that I am more than happy to take the amendment away to consider it, so that gets me off to a good start today. We had an interesting session last night about types of carbon units. The noble Duke read them out: the assigned amount unit, the emissions reduction unit—I also have the certified emissions reduction—the removal unit and then the EU allowance. We are considering whether to use the existing accounting system under Kyoto and in the EU Emissions Trading Scheme, where most of those are found, or whether to create a new accounting system. Clause 21 states that carbon units can be counted only if they represent a reduction in greenhouse gas emissions, removal of greenhouse gases from the atmosphere or an amount of permitted emissions of greenhouse gases with a capped system. That mirrors the international carbon accounting rules, where those are the only types of carbon units allowed to be used. I accept the strength of the argument. I cannot accept the amendment, but it is obviously important that any carbon units used under the Bill are of the right standing and environmental rigour. There is no question about that. We will certainly consider this point in advance of Report.
