Dubai has retained its position as the world’s cleanest city for the sixth consecutive year, according to results linked to the Global Power City Index published by the Mori Memorial Foundation.

The emirate recorded a 100% satisfaction score in the city cleanliness indicator under the environment pillar of the index, which evaluates major global cities across six categories: economy, research and development, cultural interaction, liveability, environment, and accessibility.

Officials said the ranking reflects coordinated efforts between government entities, the private sector, and residents to maintain sanitation standards across the city.

Dubai’s cleanliness system is overseen by Dubai Municipality, which operates a round-the-clock waste management network supported by a fleet of 785 specialized vehicles and equipment. The system also includes more than 23,300 waste storage and collection units and a workforce of nearly 3,200 personnel, including sanitation engineers, supervisors, and inspectors.

The program covers approximately 2,400 kilometers of main roads and highways, 1,419 kilometers of investment zones, and about 33.4 kilometers of water canals, in addition to residential neighborhoods, industrial areas, markets, and beaches.

Waste management initiatives are also linked to broader sustainability goals under the Dubai Integrated Waste Management Strategy 2041, which aims to reduce waste generation, divert waste from landfills, and expand circular economy practices.

Marwan Ahmed bin Ghalita, Director General of Dubai Municipality, said the ranking reflects long-term planning and collaboration across sectors.

“Dubai’s continued global leadership as the world’s cleanest city reflects a clear vision supported by sustained institutional efforts and strong partnership between government entities, the private sector, and the community,” he said.

The municipality also operates the Warsan Waste-to-Energy Centre, one of the world’s largest waste-to-energy plants, alongside recycling programs and digital monitoring systems to improve waste collection and environmental management across the emirate.
