Since the early 1990s, Sony sites throughout the world have sought certification under ISO14001 and this was achieved in early fiscal 2000.
In fiscal 2003, Sony further developed this activity by implementing a group-wide, globally integrated environmental management system.
In fiscal 2005, all Sony Group sites, including the Sony Group's headquarters, which represents the core of this management system, acquired integrated ISO14001 certification in accordance with the fundamental requirements of this integrated management system.
