According to Serbian Economist, Krakow, Poland, has been recognized as the cleanest city in the world by Radical Storage, which analyzed more than 70,000 tourist reviews of the 100 largest destinations from Euromonitor International’s Top 100 City Destinations index.
According to the study, 98.5% of reviews mentioning Krakow’s cleanliness were positive. The top five also included Sharjah in the UAE (98% positive reviews), Singapore (97.9%), Warsaw (97.8%), and Doha (97.4%).
The top 20 cleanest cities in the world include Krakow, Sharjah, Singapore, Warsaw, Doha, Riyadh, Prague, Muscat, Dubai, Fukuoka, Abu Dhabi, Zurich, Edinburgh, Los Angeles, Lima, Cancun, Porto, Copenhagen, Taipei, and Valencia, with all of them receiving over 94% positive reviews for cleanliness.
Radical Storage indicates that it selected 100 cities from the Euromonitor Top 100 City Destinations index for analysis and reviewed the 10 most popular attractions in each city. Only English-language Google reviews from October 2024 to November 2025 that contained the words “clean” or “dirty” were taken into account, after which the mentions were classified as positive or negative. A total of 71,692 mentions of ‘clean’ and 10,165 mentions of “dirty” were processed.
According to the company, the authors of the study attribute the high rankings of Krakow and Warsaw to Poland’s investments in waste management systems and the improvement of public spaces, as well as the involvement of residents in city clean-up campaigns.
Serbian cities are not included in the study.
