Who We Are


The mission of the National High School Climate Forum (NHSCF) is to foster an exchange of ideas between high school student environmental leaders from across the country, in addition to educating students from our member schools about climate change and related topics. Today, the NHSCF involves 159 schools from 38 states, split into 4 regions.


What We Offer


Since our founding in September 2020, the NHSCF has approached our mission through three means: 1) Monthly newsletters to promote specific initiatives at our member schools, 2) Speaker Events, contributing to education on a host of environmental topics, and 3) the NHSCF Annual Youth Summit, which concludes each year.

Monthly Newsletters


  We publish newsletters most months of the school year, consisting of sustainability tips, interesting resources about current events in climate change, information about environmental program opportunities for high school students, and, of course, highlighted articles about initiatives taking place at our member schools. We strive to distribute newsletters that will benefit our member schools advance their own projects.

Speaker Events


  Each Fall and Winter, we host themed speaker events, in order to fulfill our mission to educate students at our member schools on climate change, sustainability, and related topics. Past speaker events have been focused on wildfires, sustainability on college campuses, the impact of climate change natural disasters, and the power of AI in shaping the future of conservation and climate strategies. Through these events, we have hosted top climate researchers and leaders at NOAA, IBM, Microsoft, the U.S. Forest Service, Princeton University, Bates College, and more.

Annual Summit


  Each Spring, the NHSCF hosts our annual Youth Summit, the culminating and final event of the school year, in which students from our member schools have the opportunity to present on their work. In addition to our student presenters, we have hosted top leaders from General Motors, Conservation International, First Solar, eocAmerica, and the World Wildlife Fund at our 2021 and 2022 Summits. Our 2022 summit also featured opening remarks from U.S. Sen. Cory Booker (D - NJ), in addition to presentations by student representatives from sustainability groups at Yale, the Massachusetts Institute of Technology, the University of California, Los Angeles, and the University of Pennsylvania.
