Things To Know When You Apply

Impact is part of the The Public Interest Network. We're a group of organizations working to address problems our society can’t afford to ignore—from preserving irreplaceable resources like air, water and a livable climate; to transforming vast systems of transportation and energy that were designed to meet the needs of a different century; to growing and distributing food in ways that won’t destroy the environment and threaten human health.

Throughout The Public Interest Network, we believe that a clear vision, commonsense ideas, a fact-driven case for action, and the power of bringing people together are the necessary ingredients to any successful effort to solve society's problems. We share a set of core values and a strategic approach to making positive change. Click here for things you should know about our network when you apply.
