Use of indexes in evaluating environmental and health efficiency

Widespread in THE literature is the conclusion that air pollution is associated with various health problems. The present study discusses two discrete Data Envelopment Analysis (DEA) models and two related indexes. This approach has been adopted in previous research by Halkos & Argyropoulou (2021a, 2021b, 2022). Consequently, this paper uses inputs and insights published in the above-mentioned studies to evaluate the efficiency of managing pollutant levels in terms of health status at a country level. The main objective here is to offer useful tools to researchers, so that depending on their needs they can refer to the appropriate methodology, comparing the above evaluation models and presenting their capabilities, advantages and disadvantages.
