youth and schools to take action.
Youth Climate Ambassadors Community Impact Projects
A core component of the Youth Climate Ambassadors (YCA) program is for students to translate their new knowledge and skills into local climate action through Community Impact Projects (CIP). The YCA community impact projects are youth-created and youth-led and provide sustainable solutions to local problems that contribute to climate change. Projects address topics in biodiversity, energy, transportation, food, water, and waste, and seek to build awareness, drive positive environmental change, and inspire others to act on climate change.
Featured Community Impact Projects
Youth Climate Ambassadors drive local climate action countywide.
Clean Energy Workshop at Pacifica Sanchez Library
YCA students taught a workshop to kids in Pacifica about clean energy and ways to reduce carbon emissions at home and in your community. They also taught participants how to make mini windmill kits that use wind energy to power an LED light in order to explain the mechanics of sustainable energy generation.
Habitat Restoration in Redwood City
Students worked with Grassroots Ecology to host an event in Stulsaft Park that focused on removing invasive species and educating twenty attendees about the impacts that climate change will have on biodiversity.
Food Waste Education at Serendipity Elementary School
YCA students gave a presentation to local elementary school students about waste sorting and the impact that waste has on our environment. They also brought educational sorting games and engaged with over 250 elementary school students and many teachers.
Energy Saving Toolkits at Carlmont High School
Inspired by the Check-It-Out! Home Energy & Water Saving Toolkits, YCA students shared energy savings toolkits with their classmates in order to promote greenhouse gas emissions reduction both at home and in the classroom. Students worked with Sustainability Department staff to prepare 50 toolkits and educational materials to share with peers and teachers.
Water Barrels at South Hillsborough Elementary School
YCA students worked with a local elementary school to install rain barrels in an outdoor learning space to collect rainwater and increase resilience in the face of potential drought and other climate change impacts.
