We need to acknowledge that, to date, there has not been the most effective provision. Indeed, in April, we altered the fuel measurement and sampling requirements on energy-from-waste plants to secure ROCs in response to industry feedback that the previous requirements were too arduous. We have seen a positive response to that, and departmental officials are working with industry representatives and Ofgem to establish new measurement techniques. As the hon. Lady knows, the Government support energy-from-waste plants. We have made a significant sum of money—about £2 billion—available to do that. A number of huge projects are on the stocks and we expect them to come to fruition soon. In May, the largest one was finalised in Greater Manchester.
