In 1999, Goodstein founded the Green House Network, an organization dedicated to supporting the clean energy movement. As the volunteer executive director of the organization, Goodstein led a series of weekend training workshops in grassroots organization and outreach, based in part on the techniques and principles of the Highlander Center, training over 600 volunteer educators. Goodstein also set up a national speakers’ bureau of climate, energy policy, and environmental experts, preceding Vice-president
Al Gore's Climate Project speaker-training initiative. Between 2000 and 2004, Goodstein worked with Matthew Follett to produce the Race to Stop Global Warming, a 10K non-competitive footrace that involved thousands of runners and their families in eight cities across the United States. These efforts earned the Green House Network the U.S. Environmental Protection Agency (EPA)'s "Climate Saver's Award". In the winter of 2006, a rising sense of personal urgency about the need for action led Goodstein to expand the scale of his work, and launch the first of the national teach-in initiatives, Focus the Nation. Goodstein, with his wife and the project Communications Director, Chungin Chung, spent eighteen months traveling across the country, speaking and organizing on over 150 campuses. In January 2008, over 1900 universities, schools, and civic groups nationwide participated in what amounted to one of the largest teach-in in U.S. history, involving over a million people in an event designed to educate and engage Americans in a discussion of global warming solutions. Goodstein and Chung organized a second teach-in in 2009. At Bard, Goodstein has continued to lead climate educational initiatives, including, from 2020-2026, events under the heading of WorldWide Climate and Justice Week. At Bard, Goodstein initiated and directs the C2C Fellows Program —a national network of undergraduates and recent graduates who aspire to sustainability leadership in business and politics. C2C Fellows runs weekend skills training workshops across the country, helping young people develop paths to leadership careers from which they can make a difference in the world, while in their 20s. ==Writing==
