Every Angeleno breathes the country's worst air, but residents in some L.A. neighborhoods are literally poisoned in their own homes, when they go outside to tend their backyard gardens or walk their children to school. Pollution-linked illness is 2 to 3 times higher in these neighborhoods than it is in other communities. Liberty Hill invests in environmental justice.

Liberty Hill environmental investments target low-income communities of color where L.A.'s pollution has its most deadly consequences. The change we make in these densely polluted neighborhoods benefit every Angeleno, but most of all, the tens of thousands of families who are being choked by truck and train pollution, factory toxins, and ship and plane exhaust every day.

Scientists call this concentrated exposure "cumulative impact." Liberty Hill calls it a matter of life and death.

The environmental justice movement, in which Liberty Hill has played a lead role for 15 years, seeks to ensure that every Angeleno can live, work and play in a healthy environment.

Liberty Hill's Approach

Liberty Hill has pioneered a highly effective organizing and research model, bringing together academic researchers and community leaders in strategic alliance.

NEW! Read Hidden Hazards: A Call to Action for Healthy, Livable Communities, just published by Liberty Hill. It is the basis for the new Clean Up Green Up campaign.

Read the report that documents our model. Building a Regional Voice for Environmental Justice Collaborative.

Read how Liberty Hill used this model to document toxic sources in heavily polluted neighborhoods.



Thousands of Californians die each year because of particulate pollution. Now L.A. urban eco-leaders like Ashley Hernandez are calling for change. She's active in the Clean Up Green Up campaign.  Watch the video.
