This year's review deals with the performance of the UK operations of ScottishPower against 12 impact areas that were identified in consultation with stakeholders in 2005.

In 2008 our CSR Annual Review no longer includes details about ScottishPower Renewables as this is now part of Iberdrola Renovables which was floated as a separate company on the Spanish Stock Exchange in December 2007.

To get more information about ScottishPower Renewables CSR performance, please view the Iberdrola Renovables Sustainability Report 2008.

For comparison purpose we have restated our figures for our 2007 performance to remove ScottishPower Renewables information, unless otherwise stated. We have noted this where this has not been possible.

Core, is now included in our figures, unless otherwise stated.

We give details on ash reused by ScotAsh, our joint venture with Lafarge Cement. ScotAsh performance is not included in any other areas of this Annual Review. For more information on their performance, see the Corporate Social Responsibility section of their website.

This Annual Review covers the calendar year 2008 and all data relates to that period unless otherwise stated. Where we refer to data or events outside that period, it is to provide context for our policies or performance.

We have continued to track developments in good reporting practice and review our reporting against corporate social responsibility performance indicators including the AA1000AS (2008).

Except where otherwise stated, performance information is selected, measured and reported using recognised standards and protocols, in many cases set by our regulators: Ofgem (Provision of Energy; Customer Experience; Customers with Special Circumstances; Health and Safety); Environment Agency and EU ETS (Waste and Resource Use; Climate Change and Emissions). Employee data is collected and reported in line with the GRI G3 guidelines.

The audience for our Corporate Social Responsibility Annual Review is internal and external stakeholders: employees, shareholders, investors, analysts, customers, Government, non-governmental organisations, community groups, corporate social responsibility and industry analysts and other opinion leaders.
