Researchers at Yale University and Columbia University teamed up with the World Economic Forum to measure environmental cleanliness and friendliness by creating an assessment called the Environmental Performance Index (EPI).
The EPI measures 32 indicators from 11 categories that focus on ecosystem vitality and environmental health to determine which countries can be categorized as the cleanest countries.
Launching the World Population Review, here are some of the countries with the highest levels of hygiene in the world in 2020.
With an EPI of 82.5, Denmark is the cleanest and most environmentally friendly country in the world.
Denmark stands out for its high scores in several categories, including Wastewater Treatment (100), Waste Management (99.8), and the Species Protection Index (100).
Government policies to reduce greenhouse gas emissions and prevent climate change are also considered comprehensive for the population.
The country is focused on sustainability, as shown by the increasing number of eco-friendly hotels, solar powered boats, and organic food consumed in the country.
