Sustainable development is the key problem of our age in the solution of which all players of economy and society must take part in. Without the most important fundamental units of the economy, the companies it is unthinkable to realize the paradigm shift that is indispensable for the profound reform of social-economic processes. In the past three decades companies all over the world have paid more and more attention to understanding the problems of environmental protection and its sustainability and especially to the practical duties related to them. In my study I shall elaborate on this ramifying process with special attention to what opportunities are available for companies to publish their environmental-conscious approach authentically. With customers getting more and more environmentally conscious and the administrative regulations getting stricter and stricter companies became forced to make their commitment to environmental protection widely known for the public.The analysis should help and should be useful to additional survey in companies, or anyone else who may be concerned with this theme.
