Cleanest Cities in the U.S., According to Experts

1. Honolulu, Hawaii

Looking for the cleanest city in America? Set your sights on Honolulu, which consistently ranks at the top of cleanliness metrics according to multiple evaluators, including the American Lung Association. This tropical capital boasts the lowest air particle contamination of any U.S. metropolitan area, serving its population of nearly 975,000 with remarkably clean air and pristine shorelines.

The city’s commitment to environmental health goes far beyond its natural advantages. According to The Discoverer Blog, Honolulu has launched ambitious sustainability initiatives focusing on solar energy, carbon offsetting, and water conservation. Perhaps most impressive is their pledge to plant 100 million trees by 2031 – a massive undertaking that demonstrates their dedication to maintaining their status as America’s cleanest city.

This Pacific paradise isn’t resting on its laurels, either. Bob Vila.com points out that Hawaii’s capital continues strengthening its green initiatives, making it an ideal destination for both residents and visitors seeking fresh air and clean living. The city’s minimal ozone pollution levels is just another reason that it’s America’s cleanliness champion (Briefly).

2. Charlotte, North Carolina

Charlotte, North Carolina’s largest city, is making its mark as one of America’s cleanest urban centers. According to Cheapism, the Queen City ranks in the top 10 nationally for both low pollution levels and clean living conditions, with particularly high scores for infrastructure quality.

This relatively young metropolis, as noted by Money Talks, benefits from its modern development, contributing to its pristine appearance. The city’s commitment to cleanliness extends to waste management, with GovLoop reporting a 20% recycling rate – impressive considering North Carolina lacks comprehensive statewide recycling requirements.

Beyond NASCAR and banking, Charlotte’s gleaming reputation stems from its well-maintained streets, neighborhoods, and infrastructure. Money Talks notes the city scores among the top 10 in three major categories assessed by LawnStarter: pollution control, living conditions, and infrastructure quality, demonstrating its comprehensive approach to urban cleanliness.

 3. Long Beach, California

Long Beach, California has earned the title of America’s cleanest city according to Forbes, scoring an impressive 7.02 out of 10. The city excels particularly in restaurant cleanliness, EV adoption, and garbage disposal satisfaction, as reported by Insure My Trip.

This success aligns with California’s broader environmental leadership. Forbes highlights the state’s ambitious regulations, including requirements for 15% zero-emission vehicles in new car sales by 2025 and green building standards mandating renewable materials and reduced energy consumption.

The city’s residents play a crucial role in its environmental success, particularly in EV adoption. Family Beautiful notes that California dominates the national electric vehicle market, accounting for nearly 47% of all U.S. EV sales, with Long Beach residents consistently leading this charge.

4. Bellingham, Washington

Nestled between eco-conscious Seattle and Vancouver, Bellingham shines as one of America’s cleanest cities. According to The Discoverer Blog, this Pacific Northwest gem offers stunning views of the Salish Sea and Cascade Mountains, where visitors can spot rare orcas or trek the rugged Cascade Pass Trail.

The coastal Washington town doesn’t just benefit from its pristine location – as Bob Vila.com notes, it boasts clean ozone levels and minimal particle pollution. Adding to its environmental credentials is one of the strongest local activism communities in the country, proving that citizen engagement is crucial for maintaining urban cleanliness.

Beyond its fresh air, Briefly points out that this border town near Canada is a haven for outdoor enthusiasts. From the springtime Skagit Valley Tulip Festival to year-round hiking opportunities, Bellingham’s commitment to cleanliness helps preserve the natural playground that makes it such a distinctive destination.

5. Denver, Colorado

Denver, Colorado’s largest city and a major transportation hub, boasts impressive cleanliness metrics. According to Insider Monkey, 94% of 1.1 million households surveyed reported no nearby trash, despite the city’s significant population and industrial presence in aerospace manufacturing.

The city is actively addressing its environmental challenges through initiatives like the Department of Energy’s Clean Cities Coalition. Bob Vila.com reports this program is tackling Denver’s ozone pollution issues through hybrid and electric technology adoption, improved fuel efficiency, and community engagement programs.

However, the picture isn’t entirely rosy. GovLoop points out that despite Denver’s progressive reputation, its recycling rate sits at just 14%, and Colorado lacks comprehensive recycling legislation and container deposit programs. This suggests room for improvement in the city’s waste management practices.
