Abstract

This paper presents an overview of environmental indexes and indicators. A short definition of some indicators is considered and a new environmental performance framework is proposed in close relation to environmental performance index (EPI). The aim is to explore the relation between indicators and as well as to find the most suited index that could gear environmental aspects towards SD. New Environmental Performance scores (i.e. new aggregate scores (NAS) according to the proposed framework) of some selected countries were used for comparison purpose and the poor performance in some policy categories was analyzed in a time series data contextually. Sri Lanka is considered as a case study. The result of the analysis shows that Sri Lanka’s performance in air pollution category and environmental burden on diseases are poor. To conclude, the environmental performance category analysis shows that the growing demand on scarce resources and pollution play an important role in environmental stress. The use of fossil fuel is the major contributor to CO2 emission in Sri Lanka. The increasing trend of CO2 emission contributes to the environmental burden of diseases and air pollution in Sri Lanka.
