Top 10 Cleanest Countries in the World: Latest Rankings

As the world faces growing environmental challenges such as climate change, biodiversity loss and pollution, the need for accurate and comprehensive environmental assessment has become more urgent than ever.

Achieving sustainability is one of the defining challenges of the 21st century, requiring countries to balance economic growth with responsible stewardship of natural resources. Identifying global leaders in environmental performance offers valuable insights into effective policies and practices that can inspire other nations to follow more sustainable paths.

The 2024 Environmental Performance Index (EPI) is widely regarded as the most authoritative framework for measuring how countries are addressing their environmental responsibilities. Built on years of scientific refinement and robust data collection, the EPI evaluates environmental performance using a broad range of indicators.

The index incorporates 58 carefully selected indicators across 11 issue areas, including air quality, water resources, biodiversity conservation and climate action. It assesses 180 countries worldwide, providing a standardised and objective framework that allows for comparison across diverse political, economic and geographical contexts.

The strength of the EPI lies in its ability to transform complex environmental data into actionable intelligence. By compiling and analysing vast datasets, it produces a clear and objective scorecard that highlights how countries perform against established environmental targets. This evidence-based approach removes subjectivity and provides measurable insights into global environmental performance.

For policymakers, the EPI serves as a vital resource for setting priorities and refining policy agendas. It offers a shared framework that fosters constructive dialogue between governments, institutions and stakeholders. Importantly, it also reveals which strategies deliver the most significant results, ensuring that limited resources are directed where they can make the greatest impact.

The EPI further supports international environmental governance by tracking progress toward global frameworks such as the UN Sustainable Development Goals, the Paris Agreement on climate change and the Kunming-Montreal Global Biodiversity Framework. This alignment ensures that the index not only reflects national progress but also connects to international sustainability targets.

The 2024 EPI highlights striking regional patterns in environmental performance. European countries dominate the highest positions, reflecting the continent’s deep commitment to environmental protection and sustainability. This success stems from comprehensive and long-term policy frameworks, effective regulatory systems and significant investment in both public and private sector initiatives.

These countries demonstrate the importance of political will, institutional strength and financial commitment in advancing environmental excellence. Their integrated approaches, which combine climate action, resource management and biodiversity protection, illustrate that sustainable development requires coordinated strategies across multiple sectors.

Understanding which countries are leading the way provides more than recognition. It creates opportunities for knowledge sharing, encourages adoption of best practices and helps build momentum for stronger global action. For developing countries, the EPI offers a roadmap for building policies that can balance growth with sustainability. For developed nations, it provides benchmarks that ensure accountability and continuous improvement.
