The primary role of WOC 4 will be to support the promotion of safety, efficiency and sustainability across the gas distribution community. The success in achieving this objective also serves as a driving force towards achieving the other strategic objectives of promoting gas as the fuel of choice, and ensuring the industry’s role as a responsible corporate citizen. Public safety & security of supply have always been the key drivers of distribution integrity management, however environmental, economic and other sustainability issues are becoming increasingly important as energy markets develop.
