One of the most often quoted reasons for having an environmental management system is ensuring that the organisation stays inside the law.
Legislation is much more than an obstacle to overcome; it's an expression of baseline social acceptability.
It is very useful to see legislation, regulations and regulators as providing precise characteristics of environmental aspects that need to be managed. In order to do this, you must understand which legal requirements apply to you and your organisation.
Compliance with legislation ensures that you avoid stringent penalties for noncompliance. It is one of the main requirements of EMAS.
