Our human race has engaged to develop various new technologies for revising Life Quality based on the assumption of limitless environmental recovery ability of the earth since Industrial Revolution. As the results, certainly we could realize the high quality of Life, but our activities including economical, industrial, political and ethical matters have been now facing to very complicated and difficult environmental problems for realizing our sustainability. As one of typical examples, many construction concepts of Eco-town have been proposed and realized by the local governments et al. But the effectiveness evaluation scheme for realizing the sustainability about Eco-towns seems not yet be established until now. On the other hand, the concept of Ecological Footprint was proposed in 1990 by Rees. W. E. of British Colombia University, Canada. Effectiveness evaluations using this method about already constructed Eco-towns and just designing Eco-towns seems better to be conducted for revising their effectiveness.
