In recent times there has been general recognition that broad based legislation, while it must remain the cornerstone of community standards, does not fully address the needs of the community for better environmental performance. Laws can only enforce to a standard, they do not encourage performance greater than the standard. This has led to various sectors of the community putting in place Quality Assurance or Best management or Codes of Practice programs for the dual purpose of encouraging members of their sector to improve their performance above the law to a common benchmark for internal reasons and to provide a vehicle to demonstrate to other sectors of the community that they are responsive to, and share, the general increased awareness and concern with respect to environmental performance.
