Cleanliness can include waste management, sanitation, clean water, air quality, and waste management.
A country with clean and healthy cities can also improve the quality of life of its citizens.
Researchers at Yale University and Columbia University in collaboration with the World Economic Forum measured the world's cleanliness and environmental friendliness in 180 countries around the world. From this research, they created the Environmental Performance Index (EPI). The EPI uses 32 performance indicators in 11 categories to assess cleanliness in a country.
