🌍 The World's Cleanest Countries in 2025 - The 5th Will Surprise You
While many of us are still debating whether that disposable coffee cup will doom civilization, some countries have already rolled up their sleeves and are taking the job of saving the planet seriously.
These 10 environmentally exemplary nations have managed to create places where breathing doesn't feel like a health risk, and where sustainability isn't just a buzzword on corporate websites.
Based on the Environmental Performance Index (EPI), these 10 nations have earned their place as the cleanest destinations in the world - perfect for travelers who prefer adventures with fresh air and a clear conscience.
🌱 What is PPE?
The Environmental Performance Index (EPI) is a collaboration between researchers at Yale and Columbia universities, in partnership with the World Economic Forum. It evaluates 180 countries on 58 environmental indicators, grouped into 11 categories, with scores from 0 to 100 - the higher the score, the better the environmental performance.
The three main areas evaluated are:
- Environmental health: air quality, sanitation, access to drinking water, exposure to heavy metals and waste management.
- Ecosystem Vitality: management of natural resources, biodiversity, land use, fishing and agriculture.
- Climate Performance: climate change mitigation and adaptation policies, including greenhouse gas emissions and the transition to renewable energies.
