My Lords, as the noble Baroness, Lady Worthington, has said, Amendment 27 proposes that if carbon intensity has increased from the previous year, the Secretary of State will report additional actions he or she will take to reduce carbon intensity. I agree with the noble Baroness that it is sensible that, in addition to setting up plans for meeting the target range and the progress made towards it, the Secretary of State should also explain the action he or she will take to stay on track towards the target over time. However, I do not feel that the amendment as it currently stands achieves that.
My main concern is that the amendment would require the Secretary of State to set out additional action in response to an increase in a single year and this may not reflect, as the noble Baroness has rightly said, a number of variants under which the power sector operates in practice. There are many factors that can affect year-on-year measurements of carbon intensity and she has rightly said that cold years often require higher carbon intensities. Another factor could be power stations being offline for maintenance. This has been the case in recent years with some nuclear power stations, the emissions effect of which was reported in our annual statement of emissions. While bearing these points in mind, I support the aim of transparent reporting but it must be meaningful for the power sector to do that in the context of long-term trends rather than year-to-year variations. Therefore, while I support the aim of the amendment, I need to consider further how to address it, perhaps with a view to responding to it at a later stage. With that, I hope that the noble Baroness will withdraw her amendment.
