The Esperanza EnvironmentalJustice Project was founded by Enrique Valdivia to further networking and collaboration for environmental justice organizing in San Antonio. Since 1998, this project has conducted health surveys, helped to organize communities to fight a Browning Ferris Industries landfill, held informational summits about the local electrical company and air pollution, and more.  The Project documented some of it's efforts in two "State of the Neighborhood Reports."  The first report, One Hundred Years of  Solid Waste focuses on the struggle between corporate giant Browning Ferris Industries and the communities in and around Martínez Texas.  The second, Toxic Wasteland is a short history of the environmental justice movement in East San Antonio.

The Project's San Antonio partners include the Eastside based Neighborhoods First Alliance (NFA), the San Antonio Coalition For Environmental & Economic Justice (SACCEJ), United Homeowners Improvement Association (UHIA) and the Martínez Environmental Group.   Austin partners include the Sustainable Energy & Economic Development Coalition (SEED).
