Abstract

This study ascertains the link between the level of cleanness and life expectancy. Using secondary literature on environmental performance, statistics from 2022 were drawn using descriptive indices on environmental performance indices to assess the link between cleanness and life expectancy. The outcomes suggest that analysis of the potentially influencing factors of life expectancy is necessary. On balance, nations are expected to achieve the benchmarks set under the Sustainable Development Goals of the United Nations to realize a more sustainable future. Despite this, the explanatory variables used in the study were specific to the evaluation of life expectancy across selected countries, namely: biodiversity vitality, ecosystem services, fisheries resources, acidification, agricultural use of pesticides, water resource treatment, air quality, sanitation of drinking water, and waste management. From obtainable statistics, it can be stated that any improvement in a country's Environmental Performance Index (EPI) scores is likely to raise the life expectancy of its citizens. Certainly, the EPI score appears to have a positive relationship with the level of life expectancy, following the level of overall development in the country, suggesting that poor people (in less-developed countries) are likely to become immune to some EPI indicators, unlike rich citizens in more-developed countries. The outcomes of this study are instrumental in facilitating policymakers and academics to evolve better interventions linking cleanness to life expectancy. 

Key words: Cleanness, life expectancy, environmental performance index.
