The environment and the role of gas

Environment protection and an increasing awareness of ecological problems have become one of the dominant questions as the end of our century approaches. Accordingly, these issues become key factors in energy policies. Whereas the choice of an energy source associated with a project was previously based on two criteria only - the availability of various fuels in the area and the projected total cost of development and operation - today such decision also takes into account a third fuel-choice parameter which is the environment impact of the energy source. In addition, industrial firms implement processes which are more respectful of the environment. (author)
