Economic aspects of environmental investment in plant facilities

This paper discusses what kind of investment in environmental equipment is desirable in enterprises such as the petrochemical companies in Yokkaichi, which are mainly based on large production facilities. In Yokkaichiʹs case, this kind of investment was undertaken after harmful atmospheric pollution had already become a serious problem, but the present research concludes that it would normally be more effective, in terms of equipment and damage costs, to include environmental investments from the starting stages of production.
