After the five years´ existence of the Czech Law on Environmental Impact Assessment (No. 244/1992) the first two governmental economic conceptions were evaluated from the viewpoint of their environmental consequences – the proposal of state energy policy (Ministry of Industry and Trade of the Czech Republic) and the proposal of the development of traffic network (Ministry of Traffic and Telecommunications of the Czech Republic). Further to the conclusions of the public discussion and wide medial campaign and in cooperation with pertinent non-governmental organizations and associations of experts the first version of both conceptions has been finished and completed by the mover of the conception. By comparison of rational developmental alternatives in the given sector it is possible to reach a more practical effect than by pure criticism of the only "official" conception. These alternatives have to express the corresponding technical possibilities of the further development, to consider the economic correlation of given trends as well as to respect the opinion streams of professional and civil associations. So it is possible to form a space for look after the consensus in the spheres where the governmental executive met with unavoidably incompatible but rationally understandable attitude of the public.
