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:

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.

German aviation vlogger Josh Cahill, known for his candid airline reviews and a YouTube following of over 788,000, has made headlines after being seen onboard a Qatar Airways aircraft at the 2025 Paris Air Show—his first time on the airline’s plane since a high-profile ban in December 2023.

The controversy began when Cahill published a critical review titled “The Shocking Decline of Qatar Airways,” documenting his negative experiences on a flight from Colombo to London via Doha. The review highlighted issues such as dirty bathrooms, unhelpful crew, and outdated cabins, quickly drawing widespread attention and sparking debate among aviation enthusiasts.

Qatar Airways, displeased with the negative publicity, reportedly offered Cahill a complimentary flight in exchange for removing the video a request he refused. The airline then asked for the removal of negative comments about employee working conditions, which Cahill also declined.

After these refusals, Qatar Airways attempted to have the video taken down from YouTube, citing privacy concerns for crew members. YouTube sided with Cahill, leaving the video online. The airline then invoked its contract of carriage, which prohibits unauthorized onboard filming, and informed Cahill by email that his upcoming booking was canceled and that he would not be allowed to make future reservations.

The fallout extended beyond Cahill. According to sources cited by Cahill, the entire crew from his reviewed flight was reportedly terminated after the airline failed to remove the video, though this has not been independently substantiated. Cahill has since appealed to Qatar Airways’ new CEO, Badr Al Meer, to reconsider the crew’s dismissal.

At the 2025 Paris Air Show, Qatar Airways featured a static display of its Boeing 777-300ER. As is customary at such events, attendees including Cahill were allowed onboard to view the product. Qatar Airways staff, apparently unaware of his ban, welcomed him aboard, and Cahill posted a photo from the QSuite Business Class on social media, captioning it: “Perhaps Qatar Airways will unban me now”. The airline has consistently declined to comment on the incident or clarify the current status of the ban.

Cahill’s experience has intensified debate over airline transparency and the rights of online reviewers. He has expressed concern that banning passengers for negative reviews sets a troubling precedent for censorship in the industry. His story has garnered thousands of comments online, with many viewers criticizing Qatar Airways’ handling of the situation.

The incident comes amid several major developments at the Paris Air Show, including substantial aircraft orders by Riyadh Air and LOT Polish Airlines, temporary booth closures by Israeli defense companies due to political tensions, and Boeing’s subdued presence following a recent fatal crash involving the 787 Dreamliner.
Cahill’s unexpected return to a Qatar Airways cabin—albeit on a non-operational aircraft—adds a new chapter to a saga that continues to spark discussion across the aviation world.

 

Qatar Airways has once again soared to the pinnacle of global aviation, clinching the title of World’s Best Airline at the 2025 Skytrax World Airline Awards. The announcement, made during a gala ceremony at the Paris Air Show, marks a record-breaking ninth win for the Doha-based carrier, reaffirming its dominance in an intensely competitive industry.

The Skytrax Awards, widely regarded as the “Oscars of aviation,” saw Qatar Airways outpace industry heavyweights including Singapore Airlines, Cathay Pacific, Emirates, ANA All Nippon Airways, Air France, and Swiss International Air Lines. Singapore Airlines, last year’s winner, secured the runner-up spot, while Cathay Pacific rounded out the top three.

Qatar Airways also swept several major categories, taking home accolades for World’s Best Business Class, Best Airline in the Middle East, and Best Business Class Airline Lounge for its Al Mourjan Lounge – The Garden at Hamad International Airport. The carrier’s relentless pursuit of excellence and innovation was cited as a key factor behind its continued success.

“Being named the World’s Best Airline by Skytrax for the ninth time is an extraordinary honour. This recognition is far more than an award, it is a celebration of the passion, precision and purpose that defines who we are as an airline,” said Qatar Airways Group CEO, Engr. Badr Mohammed Al-Meer.

The 2025 awards highlighted a reshuffling among the world’s top airlines. Singapore Airlines, while dropping to second, maintained its lead in premium services, winning the World’s Best Cabin Crew and Best First Class. Cathay Pacific’s surge to third place was credited to its revitalized long-haul service and top-tier inflight entertainment.

Rounding out the top five were Emirates and ANA All Nippon Airways, both recognized for their business class and airport service innovations. More than 325 airlines were evaluated, reflecting the breadth and depth of global competition.

Industry observers point to Qatar Airways’ unwavering commitment to service, innovation, and passenger comfort as key factors in its success. The airline’s recent historic order of up to 210 widebody jets, including 130 Dreamliners and 30 Boeing 777-9s, underscores its ambition to redefine the future of air travel. Its focus on seamless travel experiences, from luxury lounges to onboard hospitality, continues to set new benchmarks.

With this latest victory, Qatar Airways has cemented its status as a global standard-bearer for airline excellence. As the industry braces for a surge in post-pandemic travel, all eyes are on the innovations and service strategies that will define the next era of flight.

Emirates, the UAE’s flagship carrier, has once again been recognized among the world’s top airlines, securing the No. 4 position in the 2025 Skytrax World Airline Awards, announced at the Paris Air Show. The rankings saw Qatar Airways retain the top spot for a record ninth time, followed by Singapore Airlines and Cathay Pacific. Japan’s All Nippon Airways rounded out the top five, with Emirates reaffirming its place among the global elite.

The Skytrax awards, based on feedback from over 22 million passengers worldwide, highlight excellence across cabin service, onboard experience, staff hospitality, and innovation. Emirates’ high placement reflects strong loyalty and satisfaction from UAE travelers, especially on long-haul and premium routes.

In addition to its Skytrax success, Emirates was also named ‘Best Airline Worldwide’ for the twelfth consecutive year at the 2025 Business Traveller Middle East (BTME) Awards. The airline swept three additional categories: Best First Class, Best Premium Economy Class, and Best Airport Lounge in the Middle East. These accolades underscore Emirates’ ongoing investments in fleet upgrades, onboard product innovation, and premium ground services.

Emirates’ brand value soared to $8.4 billion in 2024, making it one of the top five most valuable airline brands globally and the most valuable outside the US. The airline’s ambitious cabin retrofit program, launched in 2022, continues in 2025 with 51 aircraft already refurbished and a target of 219 upgrades. Emirates has also received its first Airbus A350, equipped with next-generation products, and plans to serve over 70 cities with upgraded aircraft by year-end.

This year, Emirates is expanding its A350 network to seven new destinations across four continents, including Tunis, Amman, Istanbul, Dammam, Ho Chi Minh City, Baghdad, and Oslo. This strategic move further strengthens Emirates’ dominance in premium air travel and global connectivity.

Emirates’ achievements align with the UAE’s broader economic and developmental momentum. In 2024, the UAE welcomed 150 million airport passengers and hosted over 30 million guests in its hospitality sector a testament to the nation’s growing status as a global travel hub. The UAE Cabinet, chaired by His Highness Sheikh Mohammed bin Rashid Al Maktoum, has set ambitious goals for 2025, focusing on innovation, sustainability, and global partnerships to solidify the country’s position as a model for growth and progress.

The top five airlines in the 2025 Skytrax World Airline Awards are Qatar Airways in first place, followed by Singapore Airlines in second, Cathay Pacific in third, Emirates in fourth, and ANA All Nippon Airways in fifth. Other notable winners include Lufthansa, recognized as the World’s Most Family-Friendly Airline and for the Best First Class Lounge; Austrian Airlines, awarded Best Airline Staff in Europe; and Eurowings, named Best Low-Cost Airline in Europe.

Emirates’ continued recognition, fleet expansion, and premium service enhancements position it at the forefront of global aviation as the UAE pursues even greater achievements in 2025 and beyond.

 

The long-anticipated single tourist visa for Gulf Cooperation Council (GCC) countries has been officially approved and is set to be rolled out in the near future, UAE Minister of Economy Abdulla bin Touq Al Marri confirmed on Monday.

Speaking to Khaleej Times on the sidelines of the UAE Hospitality Summer Camp press conference, Al Marri announced that the unified visa plan has cleared major hurdles and is now under review by the UAE Ministry of Interior and other key stakeholders for final implementation.

“The single (GCC) tourist visa has been approved and is now waiting to be implemented, hopefully soon,” Al Marri stated.

Modeled after the Schengen visa used in Europe, the GCC Grand Tours Visa will allow foreign visitors to travel across all six GCC member states — the UAE, Saudi Arabia, Bahrain, Qatar, Oman, and Kuwait — with a single entry permit. The move is widely seen as a strategic step to enhance regional integration and streamline cross-border tourism.

Tourism and hospitality executives have hailed the unified visa as a potential game-changer for the Gulf’s tourism industry, with expectations that it will significantly stimulate both leisure and business travel — especially the growing trend of "bleisure" tourism, where professionals blend work and vacation into extended trips across neighboring countries.

Industry analysts forecast that the initiative will contribute to economic diversification and job creation, giving a substantial lift to the region’s GDP. These expectations are supported by robust data from the GCC Statistical Centre, which recorded 68.1 million tourist arrivals across the Gulf in 2023 — a 42.8% increase from pre-pandemic levels — and $110.4 billion in tourism revenue.

The UAE, a major player in regional tourism, continues to see steady growth in its travel sector. The World Travel and Tourism Council (WTTC) reported that the industry supported 833,000 jobs in the country in 2023. That number is expected to rise to one million by 2030, outpacing earlier WTTC forecasts of 928,000 jobs by 2034.

Dubai, in particular, continues to cement its status as a global tourism magnet. The emirate attracted 7.15 million international visitors in the first four months of 2025, marking a 7% year-on-year increase, according to figures from the Dubai Department of Economy and Tourism.

As implementation of the unified GCC visa nears, stakeholders across the Gulf are optimistic that the new policy will usher in a transformative era for tourism, making the region more accessible, connected, and economically dynamic than ever before.
