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.


  1. Green Corps is the nation’s most respected training program for environmental organizers.
  2. The environment is the most important challenge facing our world today. That’s why we’re Green Corps — not equality corps, not health care corps or some other corps. We are laser-focused on the environment.
  3. We’re passionate about a range of environmental issues. In Green Corps, you work on the most pressing environmental issues of the day — from saving our last wild places, to protecting our oceans, to reducing climate change pollution.
  4. We want to make the biggest positive impact we can for the planet. We work hard to create opportunities for you to do just that. But it’s up to you to rise to the challenge.
  5. To make an impact, you need training. We provide top-notch, unparalleled training in the skills of organizing and advocacy to help you launch a lifetime career of impact.
  6. Many people would pay for this kind of training. Because we work hard to fund the program, we're able to offer you pay and benefits while you learn and gain experience.
  7. We challenge you. In Green Corps, we give you a ton of responsibility, the kind that pushes you outside of your comfort zone. That’s what it takes to learn the craft of organizing.
  8. Green Corps packs a ton of experience into one short year, with organizers working in three, four or even five different cities throughout the Green Corps year on a variety of issues with multiple partner groups.
  9. This is important work, and it’s hard work. But it’s also rewarding and fun. In Green Corps, you meet amazing people among your classmates, your trainers and directors, and your campaign volunteers.
  10. The Green Corps year is just the beginning. At the end of the year, you will join a network of skilled alumni dedicating their careers to making an impact on today's, and tomorrow's, most pressing environmental issues. Green Corps will help you find your place in the movement.

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, the environment is the most important challenge facing our world today, and 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 launch a lifetime career of environmental advocacy and impact without any real experience?

In response to that question, PIRG launched Green Corps in 1992 as a field school for environmental organizers that would soon become the nation’s premier training program for this work. The program gave participants a solid grounding in the skills and theory of organizing and campaigning for the environment. But Green Corps has always been more than a school. In addition to unparalleled training, Green Corps gives participants experience running real campaigns for top environmental organizations, and it even pays participants to make a difference on critical environmental issues while they learn and launch their careers.


2022 marks 30 years of Green Corps training the next generation of environmental organizers. We’ve learned from new challenges, from weathering economic recessions and global pandemics, to evolving from landlines and fax machines to cell phones and Zoom meetings. Yet, the most important organizing skills haven’t changed: setting clear goals, crafting smart strategies, going where the fight is, and recruiting, recruiting, recruiting. As trainees and alumni, Green Corps organizers keep putting those skills to work, from campaigning for more renewable energy in states across the country, to leading the Million Solar Roofs initiative in California, to reducing deforestation across the globe.

Marie Marx Strohm Memorial Award

After a varied career in education, radio and TV, Marie Marx Strohm founded Hummingbird Productions and became one of the premier producers of short documentary films for major environmental campaigns. Her work featured the International Mitsubishi Boycott, the Great Bear Rainforest Campaign, and the International Tar Sands Campaign, among other efforts. Marie received 10 Telly Awards for her video production excellence, the Gold Special Jury Award at Worldfest Houston in 2000 for the Great Bear Rainforest Video, and an L.A. Independent Filmmakers Festival Best Short Documentary Award in 2016 for her Napa Valley Campaign video. Marie died unexpectedly of a congenital heart disease in November of 2020. Working through Marie’s family, a close friend of Marie's made a generous gift to Green Corps to be spent to recruit new organizers and establish an annual memorial award in her honor. With this award, we celebrate the achievements of a graduate who demonstrates exceptional skill in the use of media in their advocacy work.
