In 2025, the world’s cleanest countries are not just global leaders in environmental health—they are also innovators in climate policy, renewable energy, and sustainable development. These nations have earned top rankings through rigorous assessment by the Environmental Performance Index (EPI) and the Climate Change Performance Index (CCPI), which together provide the most authoritative and data-driven evaluations of national environmental performance.

The EPI, developed by Yale and Columbia Universities, uses 58 indicators across 11 categories—ranging from air and water quality to biodiversity and climate policy—to rank 180 countries on how well they meet sustainability targets. The CCPI, meanwhile, evaluates 63 countries and the EU, covering over 90% of global greenhouse gas emissions, and assesses performance in GHG emissions, renewable energy, energy use, and climate policy.

These indices are vital tools for policymakers, businesses, and communities, offering a granular view of each country’s strengths and weaknesses, helping to set targets, track trends, and identify best practices for a sustainable future. High-ranking countries benefit from advanced regulatory frameworks, greener infrastructure, and new market opportunities for sustainable technologies. Here’s a closer look at what sets each of the top 10 apart in 2025:

1. Estonia (EPI Score: 75.3)

Estonia leads the world in cleanliness and sustainability, thanks to its extensive forest cover, effective use of bioenergy, and a strong focus on natural resource management. The country has set ambitious climate goals, including a 70% reduction in greenhouse gas emissions by 2030 and carbon neutrality by 2050.

Estonia achieved an 11.3% emissions reduction in late 2024, outpacing the rest of the EU, even as its economy grew. The capital, Tallinn, has become a beacon of urban sustainability, winning the ITB Earth Award 2025 for its zero-waste Song and Dance Celebration, which drastically cut single-use plastics and promoted circular economy practices.

Estonia’s environmental policies have also led to Europe’s cleanest air and ongoing investments in wind, solar, and energy storage. However, the country faces challenges in fully phasing out fossil fuels and balancing biomass production with forest conservation.

2. Luxembourg (EPI Score: 75.0)

Luxembourg stands out as a small nation with outsized environmental achievements, earning an EPI score of 75.0 in 2024 and a 4.1-point rise over the past decade. The country leads the world in water management, boasting a near-perfect score of 90.6 in Water Resources and an astounding 99.8 in Sanitation & Drinking Water. Over 55% of Luxembourg’s land is protected, contributing to a top-tier biodiversity score of 84.8.

The nation’s capital has pioneered green investments, while advanced wastewater treatment and strict EU-aligned standards keep pollution low. While Luxembourg excels in ecosystem vitality and heavy metal pollution control, it continues to work on reducing per capita greenhouse gas emissions and curbing tree cover loss.

3. Germany (EPI Score: 74.6)

Germany ranks third globally with an EPI score of 74.6 in 2024, marking a 4.4-point improvement over ten years. The country treats 100% of its urban wastewater, achieving a high 89.1 in Water Resources, and protects a significant share of its land and seas, reflected in its 82.4 Biodiversity & Habitat score.

Germany’s robust environmental policies are complemented by massive investments in green infrastructure and renewable energy. The nation’s cities are recognized for clean air, efficient public transport, and progressive urban planning. Germany’s approach demonstrates that sustainability can go hand in hand with industrial progress, though ongoing industrial emissions remain a challenge.

4. Finland (EPI Score: 73.7)

Finland secures the fourth spot with a 2024 EPI score of 73.7, though this reflects a slight decrease from its 2014 score. The country is a global leader in public health, scoring a perfect 100.0 in both Sanitation & Drinking Water and Heavy Metals. Finland’s well-managed forests, protected natural areas, and clean air contribute to its strong ecosystem vitality.

The nation’s deep cultural connection to nature is evident in its policies, which seamlessly integrate sustainability into daily life. Finland’s challenge lies in maintaining its high standards amid growing urbanization and climate pressures.

5. United Kingdom (EPI Score: 72.7)

The United Kingdom earns an EPI score of 72.7 in 2024, up by 2.1 points over the past decade. The UK has made significant progress in reducing carbon emissions, largely through aggressive wind energy deployment and expanded recycling programs. Urban green spaces and biodiversity conservation have improved city livability and environmental health.

The UK continues to update its climate policies to meet international targets, but faces ongoing challenges with air quality in some metropolitan areas and the need for further emissions reductions.

6. Sweden (EPI Score: 70.5)

Sweden ranks sixth with a 2024 EPI score of 70.5, showing a modest 1.6-point increase over ten years. The country’s energy mix is dominated by hydropower and wind, and it is a pioneer in negative emissions technologies.

Sweden’s cities are models of sustainable urban development, and the nation’s commitment to clean air, water, and biodiversity is unwavering. However, Sweden faces pressure to further reduce emissions from transportation and industry to meet its ambitious climate goals.

7. Norway (EPI Score: 70.0)

Norway holds the seventh position with a 2024 EPI score of 70.0, up 3.6 points over the last decade. The country boasts nearly universal access to clean drinking water and sanitation, and its electricity is almost entirely supplied by hydropower.

Norway’s proactive climate policies and investments in electric mobility and carbon capture have resulted in some of the world’s lowest per capita emissions. The country’s challenge is balancing oil and gas exports with its climate commitments.

8. Austria (EPI Score: 69.0)

Austria scores 69.0 on the 2024 EPI, reflecting a slight decrease of 0.3 points over ten years. The country excels in maintaining clean cities and countryside through strict agricultural and chemical regulations. Austria’s public transport system and urban planning support eco-living, while strong environmental laws ensure high water quality and effective waste management.

Austria’s challenge is to address areas of stagnation and reinvigorate progress on climate adaptation and emissions reduction.

9. Switzerland (EPI Score: 68.0)

Switzerland earns a 2024 EPI score of 68.0, up 1.8 points over the last decade. The country is renowned for its pristine landscapes, robust waste management, and advanced water treatment systems.

Switzerland’s environmental protection laws and public engagement in sustainability initiatives help maintain high living standards and ecological health. However, Switzerland must continue to innovate in renewable energy and reduce its ecological footprint to stay ahead.

10. Denmark (EPI Score: 67.9)

Denmark rounds out the top ten with an EPI score of 67.9 in 2024, a 1.7-point increase over ten years. The nation is a global leader in wind energy and urban planning that prioritizes cycling and green spaces. Denmark’s comprehensive recycling policies and low pollution levels make it a model for clean living. 

The country’s ongoing challenge is to further cut emissions from agriculture and transportation while maintaining economic growth.

Passengers flying out of Hamad International Airport (HIA) can now enjoy added convenience with Qatar Duty Free’s newly introduced ‘Collect on Return’ service, which allows travelers to shop duty-free before departure and collect their purchases upon their return to Doha.

The service, launched as part of Qatar Duty Free’s strategy to enhance customer experience, caters especially to Qatar residents, frequent travelers, and business passengers who may want to take advantage of duty-free pricing without carrying extra bags or fragile goods abroad.

How the Service Works

Travelers departing Doha can browse and purchase items from Qatar Duty Free’s wide retail portfolio, which includes luxury fashion, perfumes, cosmetics, electronics, watches, jewelry, confectionery, and premium liquors. Once customers select their goods, they can request that the purchase be stored.

• The items are securely packaged and labeled with the passenger’s details.

• Qatar Duty Free then stores them in designated, climate-controlled facilities to protect sensitive products such as fine chocolates, skincare, and beverages.

• Travelers receive a claim voucher or digital receipt, which they present when they return through HIA.

• On arrival back in Doha, passengers can collect their purchases at special ‘Collect on Return’ counters located within the arrivals area.

This process ensures that travelers avoid carrying unnecessary weight, dealing with customs concerns abroad, or transporting delicate products during their trips.

Benefits for Passengers

1. Hassle-Free Travel – Passengers can shop without worrying about space in their luggage.

2. Security & Preservation – Goods are stored safely under proper conditions.

3. Convenience for Short Trips – Particularly useful for weekend trips, business travel, or families with children.

4. Opportunity to Secure Promotions – If there are limited-time offers or exclusive products available on departure day, passengers can still purchase them without needing to carry them away immediately.

Strategic Importance

Qatar Duty Free operates in one of the fastest-growing hubs in the world, and the rollout of this service is seen as another step to match and surpass global standards in travel retail.

Hamad International Airport, which has repeatedly been ranked “World’s Best Airport” by Skytrax (2021, 2022, 2024), positions itself as a premium global gateway. It already boasts more than 90 boutiques and retail outlets, alongside 30 restaurants and cafés, offering both international luxury brands and local Qatari products.

By introducing ‘Collect on Return,’ QDF joins a select group of major duty-free retailers worldwide — such as those in Singapore, Dubai, and Heathrow — who offer similar services. Industry experts argue that this innovation is becoming increasingly important as passengers look for greater flexibility in how they shop, especially in the post-pandemic era where smooth, contact-minimized, and tailored services are in demand.

Official Position

QDF officials have emphasized that the service reinforces their passenger-first philosophy. “This initiative is built around convenience and peace of mind,” a Qatar Duty Free spokesperson noted in earlier statements, highlighting that the program reflects QDF’s ambition to provide not just products, but also premium after-purchase services.

Looking Ahead

Aviation analysts suggest that value-added retail services like ‘Collect on Return’ could boost non-aeronautical revenues for airports, which now account for a growing share of global airport income. It also enhances customer loyalty, as passengers are more likely to shop again if the process is streamlined and worry-free.

Travel insiders point out that this concept also reflects a wider luxury shopping trend in the Gulf region, where airports are increasingly expected to act as lifestyle destinations as much as transit hubs.

In a festive gesture to celebrate India's Independence Day, Etihad Airways, the UAE’s national carrier, has launched an exclusive discount campaign for passengers booking from India. Operating from its hub at Zayed International Airport, Etihad is offering a generous 30 percent discount on Economy class tickets to a wide array of popular destinations across Europe and the United States.

Travellers booking now can secure flights at significantly reduced rates to iconic cities such as Chicago (Dh3,273), Toronto (Dh3,599), Washington DC (Dh3,149), Barcelona (Dh2,036), and Dublin (Dh2,149). The offer also extends to flights headed to Brussels, Prague, Warsaw, Sochi, New York, Rome, Atlanta, Madrid, Boston, Paris, Munich, and Frankfurt, making it easier than ever for Indian passengers to explore these global hubs.

The special fares are available for booking up until August 15, with a travel window stretching from September 2025 through March 2026. This promotion follows on the heels of Etihad’s recent start-of-summer campaign, which included discounts of up to 25% on both business and economy class tickets.
As the 2025 summer travel season approaches its end, airlines based in the UAE, neighboring regions, and India have launched a series of competitive fare offers, heating up the market for travelers seeking value deals.

In other exciting news, Etihad recently inaugurated commercial operations of its new Airbus A321LR, with Flight EY414 marking the first journey from Zayed International Airport to the beautiful island destination of Phuket. The addition of the A321LR to its fleet underscores Etihad’s commitment to delivering premium cabin experiences on short and medium-haul flights, mirroring the attention to detail and service excellence featured on its acclaimed widebody aircraft.

With these strategic offers and fleet enhancements, Etihad Airways continues to strengthen its position as a preferred carrier for Indian travelers seeking quality and affordability on international flights.
