The mission of Green Corps is to train organizers, provide field support for today’s critical environmental campaigns, and graduate activists who possess the skills, temperament and commitment to fight and win tomorrow’s environmental battles.


Following Earth Day 1990, a wave of environmentally-minded college graduates left academia looking for a way to put their values to work. As is true today, there was no shortage of graduates who were passionate and ready to contribute to the environmental movement, but they were faced with a critical challenge: How do you find a position with an environmental organization if you have next to no experience?

In 1992, U.S. PIRG launched Green Corps as a field school for environmental organizers. But Green Corps was always more than a school. The program not only gave participants a solid academic grounding in their field of choice, but it also provided them with concrete campaign experience with leading environmental organizations, and even paid participants to engage full-time in their chosen work.


Fast forward nearly three decades: Green Corps has trained and graduated more than 400 organizers who are putting their skills to work with Environment America, Mighty Earth, League of Conservation Voters and other groups on issues ranging from saving our national parks to protecting the Arctic, from solving global warming to reforming our food system.


Green Corps is part of The Public Interest Network, which operates and supports organizations committed to a shared vision of a better world and a strategic approach to social change — from preserving irreplaceable resources such as 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.
