Those who live in cleaner countries tend to have longer life expectancies than those with dirtier surroundings. Clean water, better air quality, better handling of waste, and sanitation are all factors that significantly affect human health. For example, countries with high air quality scores and low exposure to harmful particles like PM2.5 will allow their people to be less susceptible to illnesses associated with air pollution, such as respiratory or cardiovascular disease. Countries with high pollution levels see high rates of non-communicable diseases, accounting for 72% of all deaths, 16% of which are caused by toxic pollution

Researchers at Yale University and Columbia University collaborated with the World Economic Forum to measure the cleanliness and environmental friendliness of over 180 countries around the world.

The Environmental Performance Index (EPI) ranks countries from the cleanest to the dirtiest in the world based on two policy objectives: ecosystem vitality and environmental health. The EPI ranks each country on 24 performance indicators across ten categories that cover environmental health and ecosystem vitality. These categories include air quality, water and sanitation, biodiversity and habitat, and sustainability.

The EPI allows countries to see how effective their environmental policies are and how close they are to achieving their environmental goals.

The UK has perfect scores for drinking water, sanitation, and reducing exposure to PM2.5 exposure. The UK also has high scores for both air quality and biodiversity, and habitat.

5. France

France has an EPI score of 83.95, making it the fifth-cleanest country in the world. Although France is industrialized, almost 80% of its energy is from nuclear power, significantly reducing its carbon emissions and receiving 96.82 for air pollution. France's environmental initiatives include hydro turbines along its rivers and banning supermarkets from throwing away unused, good food.

6. Austria

With an EPI of 79.6, Austria is the sixth-cleanest country in the world. Austria ranked third overall for agriculture, having stringent regulations for pesticides and fertilizers, and fifth for ecosystem vitality.
