My Lords, can I ask the Minister when she responds to comment on two points? First, if we are now to be committed in this legally strengthened way to the maximum economic exploration of our oil and gas reserves, how do the Government see that to be compatible with the commitment under the Climate Change Act to reduce our emissions to only 20% of the 1990 level by 2050 without also having a strategy for carbon capture and storage, which I think lies behind the amendment?
Secondly, the amendment refers to the economic extraction of our hydrocarbons—I have never yet heard any reliable estimate of what the additional cost will be of having carbon capture and storage on a typical power station, be it a coal station or a gas station. What level of increase per kilowatt hour—in a unit that can be easily understood—is anticipated if carbon capture and storage is required on such stations? That impacts on what is economically recoverable.
