Climate Change Bill [HL]

I see the logic of including an objective in the Bill. The arguments put forward by the proposers of all three amendments seem to me strong and convincing. This is an exceptional Bill, as the Government have said many times. Therefore, it is reasonable that it should have some exceptional features. Therefore, if it does, it is also reasonable, to depart from precedent to this extent. I see the logic of the points made by the noble Viscount, Lord Bledisloe, and the noble Lord, Lord Dixon-Smith. However, on the question of justiciability, this seems an issue which arises in relation to other targets in the Bill and not just the 2 degrees centigrade. I am not certain that this is relevant to these clauses. As far as the figures are concerned, the science has evolved. As the noble Baroness, Lady Miller, was saying, we had much evidence put to us on the Joint Committee. The science has evolved enough for specific figures to be feasible, testable and satisfactory and to be included in this Bill. Therefore, I support the direction of Amendments Nos. 1, 2 and 3. However, I believe that the clearer, shorter and simpler this Bill’s objective is, the better—in particular, with regard to clarity of the 2 degrees centigrade figure. As between the three, I would prefer the amendment in the name of the noble Lord, Lord Teverson.
