Abstract
Growth in number of population and development nowadays indicate a good sign for nation’s development. However, the development sometimes might neglects the preservation and conservation of nature and can reflects in environment performance. Concerning on this matters, Environmental Performance Index (EPI) has been introduced since 2006 to depict the environment performance for most of the countries in the world. The index considers ten policy categories associated with environmental public health and ecosystem sustainability. The main mathematics operation in establishing EPI is arithmetic mean of all ten policy categories. One of the weaknesses in the arithmetic mean is the operation might neglects some extreme values in data. Recently, Wan Ismail and Abdullah introduced the EPI using analytic hierarchy process (AHP) but the weight of policy category was not considered. This paper proposes a new ranking of EPI using a decision making tool of weighted correlation coefficient based on intuitionistic fuzzy sets (IFS). An original data of policy categories were converted into IFSs which benefiting in considering two-sided of membership and non membership. Criteria weights for alternatives in fuzzy correlation coefficient were utilized to set new EPI for nine ASEAN countries. A new ranking EPI among ASEAN countries show that Thailand is the highest EPI followed by Malaysia. The new ranking may offer an alternative measure in evaluating environmental performance particularly for ASEAN countries.

Summary
Sustainable development can be defined generally as the situation when development and preservation on environment get balance. An unsustainable environment is the situation where the usage and development does not preserve the environment and the nature’s source had been used is more than the replenished. The widely method used to assess the environmental sustainability are Emergy Evaluation (EME) and Ecological Footprint Analysis (EFA). Ecological footprint analysis compares human demand on nature with the biosphere’s ability to regenerate resources and provide services. It is done by assessing the biologically productive land and marine area required to produce the resources a population consumes and absorb the corresponding waste using prevailing technology (Eco Greenwares, 2009). Per capita ecological footprint (EF) is comparing consumption and lifestyles and checking this against nature’s ability to provide for this consumption (Cui & Yu, 2009)
