All relevant stakeholders should formulate, implement and periodically review an integrated national policy that should be holistic and cover all aspects of environmental performance. In the process of policy development, accountability, transparency and the use of self-control and self-regulation should be observed. A national policy should create economic and social incentives for enterprises to implement control measures. It should also encourage the development of economic appraisal of environmental performance in enterprises. It should reduce the opportunities for enterprises to externalize the costs of poor practice.
Part I of the UK Environmental Protection Act 1990 contains the Integrated Pollution Control (IPC) regime and Local Air Pollution Control (LAPC) regime. Both regimes are concerned with regulating pollution from industrial processes. The first is concerned with preventing or minimising pollution of the environment due to the release of substances into the air, water or land. The second is concerned with preventing or minimising air pollution and applies to those industrial processes which are not considered to give rise to significant pollution of water or land.
Many international legal instruments concerned with the environment relate to health. Implementation of National Environmental Health Action Plans (NEHAPs) is seen as an effective tool for giving effect to such instruments and, through that, for fulfilling international obligations, strengthening regional collaboration in solving transboundary problems and improving access to information and public participation.
