Improving the health of people in and around cities, especially those most vulnerable, with information on strategies to reduce the causes and impacts of climate change.

Environmental Justice & Health

Low-income communities often are exposed to more pollution than other communities, and bear greater health burdens from that pollution.

Green Spaces & Health

Planting more plants and trees in cities—where most people live—can cool urban areas and prevent harm from heat. Spending more time surrounded by green space, like trees or other vegetation, may improve mental and physical health.

Healthy Buildings

The air we breathe in our homes and offices can have a major impact on our overall health.

Healthy Homes

Indoor air quality in the home can be an important driver of health. In homes near major current and former industrial sites, however, indoor air can be deeply polluted.

Healthy Schools

School buildings and dormitories can have an impact on both students’ health and their ability to learn.
Highway

Transportation & Health

New studies from Harvard Chan School have found that long-term exposure to even low levels of air pollution, like those found near highways or busy city streets affects our health.
