Those who reside in cleaner countries have greater life expectancies than others who live in worse environments. Clean water, better air quality, better waste management, and sanitation are all elements that substantially impact human health. Countries with excellent air quality scores and limited exposure to dangerous particles like PM2.5, for example, will allow their citizens to be less susceptible to air pollution-related ailments like respiratory or cardiovascular disease. Noncommunicable diseases are prevalent in high-pollution countries, accounting for 72 percent of all fatalities, 16 percent of which are caused by toxic pollution.
Yale and Columbia University researchers assessed countries’ environmental performance based on 25 variables, including water and air quality, habitat conservation, and the influence of the environment on human health. European countries account for more than half of the top 30, with the United States ranking 61st.
The Environmental Performance Index (EPI) rates countries based on two policy objectives: ecological vitality and environmental health, ranking them from cleanest to worst in the world. The EPI rates countries based on 24 performance indicators spread over ten areas, including environmental health and ecosystem vitality. Air quality, water and sanitation, biodiversity and habitat, and sustainability are among these areas.
The EPI enables countries to assess how effective their environmental policies are and how near they meet their environmental objectives.
So, here is the cleanest country in the world, or maybe 10 who are still trying to overcome their OCD.
