Brian Obach demonstrates how to involve students in institutional environmental policy reform campaigns as a means to teach advocacy skills. Drawing on over two decades of environmental reform work at SUNY New Paltz, New York, US, Obach demonstrates the impact of lessons learned from several successful and unsuccessful campaigns to shift policy on campus. These include efforts to eliminate single use plastics, to expand sustainable food options, to divest from fossil fuels, and to improve recycling systems and waste reduction. University institutions are a microcosm of the broader society, and experience with policy reform on campus develops the skills necessary for learners to become change agents and environmental advocates later in life. Students engaged in these efforts as interns or volunteers with faculty supervision develop advocacy skills such as how to develop campaign strategy, how to analyze power and interests, how to identify and implement tactics, consciousness raising, coalition building, how to overcome bureaucratic inertia, and how to negotiate with decision makers.
