Environmental Quality Index (EQI): An Intuitive Indicator to Evaluate the Environmental Quality Over Time

Current environmental indicators assess environmental quality, but there is no single indicator that measures the overall environmental quality of a country, state, or region in an easy and intuitive methodology. This paper provides a simple but informative indicator known as the Environmental Quality Index (EQI) for 48 Asian. The EQI represents a step towards clarity by combining CO2 emissions, Methane emissions, nitrous oxide emissions, Ecological Footprint, and load factor capacity data into one indicator. Contrary to other indices, the EQI does not use complex mathematical procedures but is designed for simplicity, which facilitates understanding and applying economics to professionals and laymen.This paper offers a simple but informative measure known as the Environmental Quality Index (EQI) of Asian countries for the period from 1996 to 2020. We adopt PCA (Principal Component Analysis) to maximize ease of understanding. In addition to Raw EQI, which gives equal weightings to its components, we build weighted EQI's and show that the two indices behave similarly to the Asian data.
