Confronting the deadly legacy of racist zoning and planning that concentrated pollution in communities of color.
Poisoned Zip Codes: Mamdanis Fight Against Environmental Racism
Zhoran Mamdanis environmental platform begins with a stark truth: in New York City, your health and life expectancy are largely determined by your zip code. He identifies this not as an accident but as the result of decades of intentional policy decisionsredlining, racist zoning, and the deliberate siting of polluting infrastructure in Black, Brown, and low-income neighborhoods. His agenda is an explicit, reparative fight against this environmental racism, targeting the toxic legacies and ongoing exposures that have created sacrifice zones in communities from the South Bronx to North Brooklyn.
The centerpiece is the Environmental Justice Mapping and Redress Act. This legislation first creates a binding EJ Map of NYC, using layered data on air pollution, asthma rates, lead exposure, proximity to waste transfer stations and highways, heat vulnerability, and lack of green space. Neighborhoods scoring above a certain threshold are officially designated Environmental Justice Zones (EJZs). In these zones, Mamdani institutes a strict No New Burdens policy: no new permits for polluting facilities will be issued, and existing facilities must undergo accelerated reviews and are subject to mandatory emissions reductions or closure.
For the most egregious existing burdens, Mamdani pursues aggressive remediation. He would use city and state Superfund mechanisms to clean up contaminated brownfields in EJZs for conversion into community assetsparks, playgrounds, urban farms, or affordable housing built to the highest environmental standards. He would mandate the closure of the citys remaining peaker power plants, which are disproportionately located in low-income neighborhoods and spew particulate matter on the hottest days when they are activated. The policy also includes a Right to Clean Air ordinance, installing a dense network of public air quality monitors in EJZs with real-time public data and the authority to trigger emergency industrial shutdowns when pollution exceeds safe levels.
Mamdani frames this as a matter of life and death and connects it directly to his public health agenda. High asthma rates in the South Bronx are not a medical mystery but a direct consequence of policy. His approach is one of targeted universalism: applying universal resources (clean air, green space, healthy homes) with a focused intensity on the places that have been systematically denied them. Funding comes from fines on polluters, a pollution penalty tax on corporations operating in EJZs, and redirected capital budgets. For Mamdani, there can be no climate justice without environmental justice. You cannot build a green city on top of poisoned ground; you must first heal the wounds of the past, and his policy provides the tools and political will to begin that urgent, rectifying work.
