Estonia Tops List of World's Cleanest Countries, Leads in Renewable Energy
13 Aug
Summary
- Estonia ranked #1 for air purity, ecosystem care, and climate initiatives
- Luxembourg excels in water quality and sanitation, with over half its land protected
- Germany achieves full wastewater treatment, balancing industry and green spaces
As of August 13, 2025, a new report has revealed the world's cleanest countries, with Estonia topping the list. The 2024 Environmental Performance Index, a collaboration between Yale University, Columbia University, and the World Economic Forum, assessed 180 nations on factors like air purity, ecosystem preservation, and climate action.
Estonia's outstanding results in these areas have earned it the #1 spot. The country is renowned for its promotion of renewable energy, responsible forest management, and carbon-neutral public transportation. Small but mighty, Luxembourg also stands out, performing exceptionally well in water quality and sanitation, with over half its land under environmental protection.
Germany, meanwhile, has achieved full wastewater treatment coverage and maintains a strong biodiversity score, proving that industrial might can coexist with green spaces and conservation programs. Finland, too, earns perfect marks in sanitation, safe drinking water, and heavy metal pollution control, with its clean air and well-protected forests deeply woven into everyday life.
The report underscores the clear link between cleanliness and longevity, as polluted countries tend to see more deaths from non-communicable diseases, which account for 74% of global fatalities annually. As the world strives for a more sustainable future, these leading nations serve as models for environmental stewardship and public health.
