Introduction
When choosing a country to live, invest, or launch a business, we often focus on taxes, residency programs, or market opportunities. But one factor that profoundly shapes quality of life—yet is often overlooked—is cleanliness. A clean environment improves physical and mental health, boosts productivity, and reflects a country’s long-term commitment to sustainability and good governance.
In this guide, we take a closer look at the cleanest country in the world, based on the 2024 Environmental Performance Index (EPI), and explore the global leaders in environmental responsibility and public health.
What Is the Environmental Performance Index (EPI)?
The Environmental Performance Index, developed by Yale and Columbia Universities, evaluates countries based on their efforts in environmental health, ecosystem vitality, and sustainability. It scores nations on multiple indicators, including air and water quality, waste management, emissions reduction, biodiversity conservation, and climate change policies.
A higher EPI score reflects better long-term strategies, stronger public health outcomes, and a cleaner, more resilient living environment—factors that matter deeply to global citizens and investors seeking a healthier, more stable lifestyle abroad.
The World’s Cleanest Countries in 2024
Here are the top-ranked countries for environmental performance, according to the 2024 EPI report:
10. Senegal (EPI Score: 43)
Senegal has focused on environmental education and urban renewal programs to address pollution and waste management challenges, marking steady improvement.
9. Germany (EPI Score: 74.6)
Germany has long been a global pioneer in renewable energy, leading the way in wind and solar infrastructure. It also maintains advanced waste recycling systems and enforces strict environmental regulations.
8. Finland (EPI Score: 73.7)
With some of the cleanest air and water in the world, Finland is deeply committed to sustainability. It plans to reach carbon neutrality by 2035 and has eliminated coal from its energy mix entirely.
7. United Kingdom (EPI Score: 72.7)
The UK has steadily reduced its emissions over the past two decades. Its ambitious net-zero plans and preservation of green spaces reflect growing environmental awareness.
6. Sweden (EPI Score: 70.5)
Sweden’s commitment to a circular economy, its low carbon footprint, and innovations in waste-to-energy systems keep it among the world’s most eco-conscious nations.
5. Norway (EPI Score: 70.0)
Norway combines sustainable resource management with high levels of social equity. It has significantly invested in marine ecosystem protection and electrified much of its transportation system.
4. Austria (EPI Score: 69.0)
Austria excels in renewable energy—particularly hydro—and enforces forest conservation measures. It has also made strides in reducing industrial emissions and protecting water resources.
3. Switzerland (EPI Score: 68.0)
Switzerland maintains rigorous standards for environmental cleanliness, especially around air and water. Strict zoning laws and environmental legislation support its clean reputation.
2. Denmark (EPI Score: 67.9)
A leader in clean energy innovation, Denmark has pledged to phase out fossil fuels entirely by 2050. Its cities are models of urban planning and sustainable living, often ranked among the most livable in the world.
1. Estonia (EPI Score: 75.3) — The Cleanest Country in the World
Estonia, a small yet digitally advanced country in Northern Europe, now ranks as the cleanest country on Earth. It has quietly built a reputation as a global leader in sustainability, environmental policy, and public health.
Why Estonia Stands Out
Environmental Policy & Governance
Estonia’s environmental policies are proactive and science-driven. The government has implemented long-term strategies focused on reducing emissions, preserving ecosystems, and promoting renewable energy—all of which helped it earn the highest EPI score worldwide.
Emission Reduction & Renewable Energy
Estonia has committed to phasing out fossil fuel dependency by 2050 and is rapidly replacing oil shale with wind, solar, and biomass. The country's consistent reduction in greenhouse gases aligns with global climate targets—an effort many larger nations still struggle to achieve.
Air Quality Standards
Air quality in Estonia meets and often exceeds World Health Organization (WHO) guidelines. Cities like Tallinn, the capital, consistently rank among the cleanest urban centers in Europe. Cleaner air translates into better public health and fewer respiratory conditions.
Biodiversity & Ecosystem Protection
With over 20% of its land designated as protected areas, Estonia ranks 7th in the world for biodiversity preservation. Its rich forests, peat bogs, and coastal wetlands support diverse ecosystems and reflect its deep commitment to natural conservation.
Digital & Sustainable Development
Estonia’s digital-first government reduces paper usage and bureaucratic waste, and it actively promotes smart energy systems and green innovation across sectors—from transportation to construction.
Why Cleanliness Should Matter to Global Citizens
Clean countries typically reflect broader qualities: strong governance, low corruption, efficient infrastructure, and high quality of life. Whether you’re moving for health reasons, investing offshore, or establishing a base for your global business, living in an environmentally responsible country offers security, peace of mind, and long-term value.
Conclusion
Estonia’s rise to the top of the 2024 EPI rankings highlights a broader shift in how countries are judged—not just by GDP or passports, but by how they care for their people and the planet. As global mobility becomes more accessible, more individuals are considering environmental performance as a core part of their relocation or investment strategy.
