We are committed to a year-by-year improvement in our environmental performance. Our environment policy sets out the key areas we are addressing, and we continue to implement environmental management systems certified to the international standard ISO 14001 to help us deliver improvements in these areas.

At 31 March 2008, approximately 66% of our employees worked to certified ISO 14001 environmental management systems compared to over 90% at the same time last year. The main reasons for this reduction were the acquisition of KeySpan operations that were not ISO 14001 certified and the disposal of our wireless infrastructure operations that were certified. During 2008/09, we will work to bring KeySpan operations in line with the rest of the Company.
