Climate Change Bill [HL]

My Lords, I certainly appreciate the commitment of the noble Lord, Lord Redesdale, to ensuring that the 2050 target for carbon emissions is robust. However, we do not think that this is the best way of gaining such a commitment. We certainly agree that the 60 per cent target is outdated. As we have noted in the House many times, that target is based on eight year-old science, and it is almost certainly not the right ultimate goal. However, we do not feel that parliamentarians should set the targets, which should be scientifically based. This is why we have tabled an amendment that would place a duty on the Committee on Climate Change to set the targets. That has been part of our position on this side of the House from the outset: science, not politics, should be the driving force behind the targets for carbon emissions. Last November, the Prime Minister said that the 60 per cent target seemed insufficient and that, in all likelihood, the overall target would be increased. We on this side of the House hope that any change in the target will be a reflection of the scientific deliberation of the Committee on Climate Change and not the result of a ministerial proclamation or even of an amendment voted on in this House. Thus, although we recognise the importance of having robust targets, we continue to insist that they must also be authoritative. Therefore, although we understand the spirit of the amendment, we cannot support it.
