To commemorate the International Day of Zero Waste 2026 (March 30), the UN Secretary-General’s Advisory Board on Zero Waste has officially announced the list of 20 cities leading the global movement toward innovative waste management. This selection is not merely an honorary list; it represents the launch of a global network dedicated to implementing circular economy models at the local level and drastically reducing the burden on landfills worldwide.
NAIROBI – The UN Advisory Board on Zero Waste, chaired by Ms. Emine Erdoğan, has launched the “20 Cities Towards Zero Waste” initiative. The selected cities are recognized for demonstrating tangible results in food waste prevention, reuse systems, and the formal integration of informal waste pickers. With the world generating between 2.1 and 2.3 billion tonnes of municipal solid waste annually—the majority of which originates in urban areas—these cities are designated as the primary engines of the global solution.
The Official List of 20 Pioneer Cities (2026)
The following cities have been selected for their leadership in zero-waste initiatives (listed alphabetically):
-
Accra (Ghana)
-
Bologna (Italy)
-
Chefchaouen (Morocco)
-
Dar es Salaam (Tanzania)
-
Dehiwala (Sri Lanka)
-
Florianópolis (Brazil)
-
Gaziantep (Türkiye)
-
George Town (Malaysia)
-
Hangzhou (China)
-
Iloilo City (Philippines)
-
Kisumu (Kenya)
-
Kuala Lumpur (Malaysia)
-
Lilongwe (Malawi)
-
San Fernando (Philippines)
-
San Francisco (USA)
-
Sanya (China)
-
Suzhou (China)
-
Varkala (India)
-
Yokohama (Japan)
-
Zapopan (Mexico)
Innovation and Quantitative Impact in Practice
These cities earned their place through real-world implementation rather than paper-based promises. The UNEP report highlights several successful practices:
-
Extended Producer Responsibility (EPR): San Francisco (USA) and Suzhou (China) have developed robust models that enforce the legal and financial responsibility of manufacturers for their products’ end-of-life management.
-
Refill Systems: Bologna (Italy) has become a pioneer through its “refill” networks designed to eliminate single-use packaging in the food and beverage sectors.
-
Informal Sector Integration: Kuala Lumpur (Malaysia) and Zapopan (Mexico) have successfully integrated informal waste collectors into the official urban management systems, significantly increasing sorting efficiency and social equity.
-
Measurable Savings: For instance, Iloilo City (Philippines) reported following the recognition that its sustainability programs have diverted 2,290 tonnes of waste from landfills and avoided nearly 2,750 tonnes of CO2 emissions.
2026 Focus: Combatting Food Waste
A central theme of the 2026 Zero Waste Day is the fight against food loss and waste. UN data reveals that humanity wastes a staggering proportion of the food it produces—a reality that is simultaneously a moral, economic, and environmental disaster. Most of the 20 selected cities (such as Kisumu and Dar es Salaam) have established specific composting and food-sharing networks to prevent organic waste from reaching landfills.
Objectives of the Initiative
The Advisory Board and UNEP support the selected cities through four primary pillars:
-
Recognition: Making local innovations visible on a global stage.
-
Exchange: Transferring “Zero Waste” solutions and lessons learned to other municipalities.
-
Inspiration: Motivating other cities to commit to circular transitions.
-
Implementation: Providing technical support for circular economy models at the local level.
Inger Andersen, Executive Director of UNEP, emphasized that cities are at the heart of tackling the “triple planetary crisis” of climate change, nature loss, and pollution. The cities on this list prove that the journey toward zero waste is achievable and sustainable at the local level.
