Take only memories and leave only footprints. Reunions undoubtedly creates unforgettable memories, but it also leaves a heavy environmental footprint. The Greening Reunions Alumni Working Group has been working since 2020 to move toward a carbon neutral, zero waste Reunions. Two initiatives were piloted this year, but significant Reunions-wide change can only be achieved if Princeton works with alumni to adopt a Reunions Sustainability Action Plan. Please consider signing the open letter to President Eisgruber in support of this: bit.ly/GreeningReunions [7]
