3 Preface  Function of sustainable development indicator  Steps of environmental indicator establishment  Indicator Structure Hierarchy  DSR framework(OECD)

4 (1)Function of Sustainable Development Indicator  Precaution: review of current environment, and social status, to provides a signal of environmental conditions change.  Policy decision: provides an effective guide for planning a sustainable environment in the future

5 (2) Steps of Environmental Indicator Establishment Characteristics of indicators Quantifies the indicators Weighed average indicators Integrated environmental indicator

6 (3) Indicator Structure Hierarchy Information Density Indicators used by scientists Indicators used by decision-makers Indicators used by the public Information Volume

7 (4) DSR Framework(OECD)  Driving forces: What is causing environmental conditions change?  State: What are the effects of human being activities on the environment?  Responses: What actions are being taken to respond to the changes in the state of environment?

20 The Data 1. The data used in this paper are based on statistics available in September 2000.Much of this data has been published in Yearbook of Environmental Protection Statistics, Taiwan Area, the Republic of china. Supplementary data have been taken from other sources as well as from selected national reports and yearbooks. 2. We remove out some issues due to the difficulties in obtaining data.

21 Normalization  Since most of the units of environmental indicators are different, the values of these indicators are transformed into between zero and one by shifting and scaling.

22 Methodology  Environment pollution indicators - equal weight  Resource quality indicators - equal weight  Living pollution indicators - equal weight  Living quality indicators - equal weight  Integrated environmental index- unequal weight above four index(108)

37 Conclusion  The last sixes year, environmental pollution improvement gets better off.  Resource quantity index look likes U shape, it means that resource quantity gets worse off initially, however, after 1993 gets better off.  Living pollution seems gets worse off with time.  Living quality gets worse off initially, until 1996 gets better off.  Integrated Environmental Index decreasing with time when the weight of environment index is greater than living index.

38  Integrated Environmental Index will upward shift with the weight of Living Index gets larger.  The value of per capita GDP deflate the integrated environmental index will increase with time.
