down. This limited adaptive capacity to urban heat is concentrated in LMI and historically segregated neighborhoods. Specifically, neighborhoods in cities that were historically targeted by redlining and divestment experience higher average land surface temperatures than surrounding areas. These differences in surface temperatures embody the legacy of discriminatory housing policies in the US, and highlight how historic urban planning practices will interact with the effects of the climate crisis. We must create the sustainable cities of the future with these historic practices in mind. The heat island effect also exacerbates the impacts of another form of environmental injustice that disproportionately affects minority and low-income groups: air pollution. Urban infrastructure projects that produce environmental toxins – like industrial plants and highways – are frequently built near or in LMI and POC communities because of favorable zoning codes, cheaper land prices, and less political backlash. This is not because residents don't care, but because they often lack the time, resources, and connections necessary to prevent such construction. In turn, pollutant-producing operations disproportionately impact LMI and POC communities, harming the health outcomes of these groups. A study by the University of Minnesota found that if nitrogen dioxide levels (NO2 – a product of the combustion of fossil fuels) in non-white communities were reduced to equal those in white communities, there would be around 7,000 fewer deaths from heart disease per year. This mortality disparity highlights the health impacts of discriminatory zoning and urban planning policies, which disproportionately expose LIM and POC communities to air pollution. The disparity also shows how much we have to gain from sustainable transportation reform which eliminates combustion-engine vehicles. The inequitable breakdown of exposure to environmental risks by race and income reinforces the understanding that the climate crisis is a social issue, and that environmental justice depends upon racial justice. There is no one right way to address these issues. Proposed solutions include eliminating single-family zoning, pricing a minimum proportions of housing units for LMI households, and requiring community engagement in future urban planning projects. To select the best combination of solutions to create sustainable cities tailored to their environments, each city must be designed for all community members, by all community members. Leaders in the environmental justice movement include Robert Bullard, Benjamin Chavis, Peggy Shepard, Kandi Moseett-White, Mustafa Santiago Ali, Jamie Margolin, Elizabeth Yeampierre, LeeAnne Walters, and Dana Johnson.
