29. environmental management
• systematically integrates environmental issues into business decisions
through use of formal management systems
• integrates health, safety and environmental management into a single
programme
• considers all environmental components in decision-making at strategic and
operational levels
• prevents waste at its source through pollution prevention techniques and
making maximum re-use of waste components, rather than installing
expensive treatment for discharges
• evaluates alternatives on a cost/benefit/risk basis that includes
environmental values
• aims at minimising resource inputs
• innovates and strives for continual improvement
31. environmental management
corporate management principles
• define corporate strategies and environmental objectives
• adopt health, safety environmental management system
• pursue technical cooperation and capacity building
• develop partnerships and communications
• initiate prevention and cleaner production techniques
• develop and maintain accident preparedness
• ensure proper assessment, evaluation and planning of projects
• training
• review and audit
37. operational practices and procedures
operational considerations
• footprint
• pollution prevention
• social/cultural interactions
• waste
• efficient use of resources
• use of local resources
• consultation and communication
• risks and impacts
• secondary and indirect impacts
• infrastructure implications
• training
39. environmental protection measures
operational considerations
• pollution prevention and cleaner production
