Mr. Brian Carroll:

What I am saying is that the legislation provides for carbon budgets.

Once the first two carbon budgets are set, they are fixed. In that way, the setting of the carbon budgets locks in that ambition. Once the carbon budgets have been approved by the Government and laid before the Oireachtas, there is no revising those except in exceptional circumstances. The first is if we have new climate obligations which are likely to be an upward revision. The second is if there is some big development in climate science that warrants their changing. They lock it in in a very hard way.
