Abstract
Studying the current environmental condition in Iran shows the unsustainability and increasing damage in its ecological atmosphere especially in the biggest human’s accomplishment in environment which are cities. Resultant conclusions of the unsustainable development were alarms for environmental policy makers and people involved in preparing a collection of analytic methods and materials for evaluating environmental results and estimating unsustainability level of places. The purpose of this study is to introduce ecological footprint as a new way to evaluate the power of urban environments. Changing a linear and generator city to a circular and dynamic city in which production, consumption and recovering act ideally, is one of ecological evaluation accomplishments. Based on this study, evaluating sustainability power by ecological footprint has been calculated for metropolitan London 5/3, Santiago 2/6 and for Tehran 3/79 per person. This evaluation shows that they have more footprints than world levels (2/3 hectare per person) which show unsustainability of metropolitan environment because of the lack of suitable management. So applicable methods, attitudes and reaching evaluable and evident results are known as positive points of the new approach especially in improving urban governance and management.

Studying the current environmental condition in Iran shows the unsustainability and increasing damage in its ecological atmosphere especially in the biggest human’s accomplishment in environment which are cities
Estimating ecological footprint of a certain population, is a multi steps process which is related to description of source consumption process, wasting and absorbing produced sources (Wackernagle and Rees,2007:65-67)
While global average use has been 2.4 for each person; calculations show that ecological footprint of London habitants is a little more than the average of England habitants (Wsp, 2003, 23)
Summary
Studying the current environmental condition in Iran shows the unsustainability and increasing damage in its ecological atmosphere especially in the biggest human’s accomplishment in environment which are cities. Based on this study, evaluating sustainability power by ecological footprint has been calculated for metropolitan London 5/3, Santiago 2/6 and for Tehran 3/79 per person This evaluation shows that they have more footprints than world levels (2/3 hectare per person) which show unsustainability of metropolitan environment because of the lack of suitable management. All of established sessions about sustainable development (table 2) and sessions that will be established in future, show ecological knowledge enhancement and human’s ideal image of suitable environment of sustainable life. They are trying to obtain some ways to obtain all their needs with the least damage to their ecological environment. Obtaining some methods that can provide suitable solutions in measuring and evaluating this pressure especially on sustainability of urban www.ccsenet.org/js
