1.In the prior year, environmental provisions in the US and the UK decreased by £176 million as a result of the change in the real discount rate from 0.5% to 1.5%. The impact of the

change in discount rate to the decommissioning provisions was recognised against the carrying amount of property, plant and equipment (see note 13).

2.Included within additions is a £496 million increase in provision related to changes in the scope of work required on the Group’s clean-up operations on the Gowanus Canal and nearby

legacy MGP sites in Brooklyn, New York. These arose from remediation design changes as communicated in the year by US environmental agencies.
