Corporate Responsibility Report 2007

Social and Environmental Data

• Conduct
• Our People
• Society
• Environment

The environment data represents 100% of the direct emissions, discharges and wastes from:

• E&P operations where BG Group is designated as the ‘operator’; and
• LNG, T&D and Power operations in which BG Group holds a total interest of over 50%. This includes MetroGAS S.A., which is controlled by BG Group (although BG Group’s direct shareholding is less than 50%).

In addition, the figures include 50% of the direct emissions, discharges and wastes from KPO, our joint-operated venture in Kazakhstan.
