The municipality’s participation in UN-Habitat’s Urban Circuit 2025 is directly aligned with the mission of promoting fairer, more inclusive, sustainable, and resilient cities, as established in the New Urban Agenda (2016) and the Sustainable Development Goals (SDGs), particularly SDG 11 — “Make cities and human settlements inclusive, safe, resilient, and sustainable.” In this context, we present the updated municipal zoning plan, whose previous version dated back to 1978 and was thoroughly revised in 2024, in line with contemporary principles of sustainable and democratic urbanism. The main purpose of the new zoning law is to reorganize land use and occupation to address current urban challenges, particularly socio-spatial inequalities, housing deficits, urban fragmentation, and the impacts of climate change. According to urban planner David Harvey (2008), spatial justice is achieved not only through the distribution of resources but through the organization of urban space to ensure equitable access to opportunities. Inspired by this principle, the new zoning plan aims to: • Reduce urban distances, promoting the idea of the “15-minute city” — a concept popularized by Carlos Moreno (2020), in which every citizen can access housing, work, services, and leisure within short distances, with neighborhood-based centralities that decentralize the city’s monocentric model. • Expand the supply of housing in well-located areas by increasing land-use coefficients along mobility corridors and areas with infrastructure, promoting intelligent and mixed densification in line with the principles of “transit-oriented development” (TOD), as proposed by Peter Calthorpe (1993). • Preserve and expand green areas and urban parks, recognizing ecosystem services as essential elements of urban infrastructure. This guideline responds to the urgent need for climate mitigation in cities, following recommendations from the Intergovernmental Panel on Climate Change (IPCC) and UN-Habitat (2022), both of which emphasize the importance of green infrastructure for urban resilience. • Create new centralities and mixed-use zones in peripheral neighborhoods, promoting local access to commerce, services, culture, and public facilities, reducing commuting distances and strengthening the urban fabric. The new zoning law is also guided by the principle of the social function of urban property, as established by the City Statute (Federal Law 10.257/2001), and by urban policy instruments that enable more balanced urban development. Bike lanes and cycle tracks were strengthened and outlined in the Master Plan, improving existing ones and expanding them throughout the city, with the goal of promoting modal shifts, encouraging active transport, and helping reduce inequalities. As urban planner Raquel Rolnik (2015) points out, “territorial planning must be an instrument for realizing rights, not merely for regulating markets.” The 2024 zoning revision was built on this perspective, seeking to include, connect, and humanize the city, overcoming the territorial exclusion model that has historically marked Brazilian urbanization. In planning the transition toward more sustainable cities, and considering that ecovillages were listed among UN-Habitat’s 100 best sustainable development practices (MAY, 2018), specific guidelines for ecovillages were incorporated into the Master Plan and the Zoning Law, encouraging the establishment and promotion of such projects within the city’s urban area. The Green Axis, established in the Master Plan, has been strengthened and expanded through biodiversity recovery programs and initiatives that generate employment and income through Urban and Periurban Agriculture. These actions help generate income for vulnerable families, promote healthy diets, and improve quality of life by creating public spaces that enhance the city’s resilience and promote climate and social justice. The resettlement of families living in flood-risk areas through the reurbanization of the Tietê River backwater, under the Rochdale Project, ensured in its first phase the provision of essential services, adequate infrastructure, paving, housing, and dignified living conditions for many families. It also restored riparian forests, eliminated sources of watercourse pollution, and implemented measures to prevent future flooding in the area. Phase II, already underway and developed with social participation in deciding on specific areas and public facilities, will be completed along with Phase III, promoting inclusion, community strengthening, and inequality reduction. Aware that landfills are not the best path toward sustainability, the municipality developed projects to implement Ecopoints, aimed at strengthening selective waste collection and recycling, launching a more robust circular economy program that both relieves and extends the lifespan of the existing landfill — with the ultimate goal of eliminating the need for such disposal methods altogether. We also began transitioning our energy matrix by replacing fossil-fuel-powered buses with an electric fleet, reducing greenhouse gas emissions as well as noise pollution in urban environments. With the goal of eradicating environmental racism, the municipality developed nature-based solutions in partnership with Euroclima, creating projects to address flooding in both consolidated urban areas and neighborhoods inhabited by vulnerable populations. Finally, through our Open Government Department, we strengthened social participation in the construction of Osasco’s Multi-Year Plan by incorporating priorities identified through pioneering participatory processes, both with municipal methodologies and through partnerships with WayCarbon and Delibera Brasil. By presenting this revision at UN-Habitat’s Urban Circuit 2025, we reaffirm our commitment to building a fairer, more compact, connected, inclusive, and sustainable city — fully aligned with Brazil’s international commitments under the New Urban Agenda and the Sustainable Development Goals.
