Once a project is ready for operation, the Health, Safety and Environment management system and other company sustainability programs help define company expectations and provide direction for managing environmental and social issues. It is the asset manager’s responsibility to direct asset sustainable development performance. Audits carried out by corporate and business unit staff are a key process by which we assure these expectations are being met. These tools are described in further depth under each topic heading throughout our Web site. For more information, please see our sections on Health, Safety and Environment Policy, Management System and Audits, Safety and Occupational Health, and Performance Metrics.
