Environmental management systems (EMS) present a new quality in relation of industrial subjects to the environment. Up to now determination and sanctional mechanisms have prevailed. EMS set out from growing importance of environmental image of the enterprise leading to wider utilization of principle of voluntary application of more consistent environmental management. The enterprise introducing EMS has economic profit from decrease of non-productive costs for duties and penalties, from arrangement of environmental management of the enterprise, from permanent care to improvement of environmental load indices, but mainly from the fact that it is more and more difficult to maintain developed markets without environmental certification of the management system. The creation of conditions for implementation of EMS is connected with the formulation of environmental production state policy. The actual process of harmonization of technical law is a basic mechanism. The government declared the National program of environmental evaluation and marking of products and it prepares the program of introduction of the EMS according to the Statute of Council of European Union No. 1836/93.
