In celebration of Earth Month and in recognition of the district鈥檚 commitment to sustainability, 天涯社区 is proud to highlight our sustainability initiatives and impact across campuses. From renewable energy and water conservation to food recovery and student engagement, our students, staff and families are working to protect our planet and inspire action to address environmental challenges.
At the heart of this work is 天涯社区鈥檚 Sustainability Team, led by Sustainability Supervisor Jennifer Razo. The team is dedicated to reducing the district's environmental footprint while empowering students and staff to take meaningful action.
鈥溙煅纳缜 is deeply committed to sustainability at every level, and that includes not just operational changes, but education and engagement,鈥 said Razo. 鈥淭hrough innovative programs and a districtwide culture of environmental responsibility, we are equipping our students to become thoughtful caretakers of the planet for both now and in the future.鈥
Reducing Waste and Feeding the Community
As part of 天涯社区鈥檚 Zero Waste Program, the district has implemented a robust Organic Food Waste Recycling and Donation Program to reduce landfill contributions, reduce methane gas emissions,听 and comply with California Senate Bill 1383. Food recovery share tables and 3-bin sorting stations help students sort leftover food scraps (green bin), recyclables (blue bin) and landfill waste (gray bin). The district has also expanded its impact through a new Food Recovery Donation Program, which provides excess, edible food to local food banks, such as South County Outreach.

A Carbon-Negative Commitment by 2025
One of the district鈥檚 goals was to become carbon-negative in 2025. Through its Renewable Energy and Decarbonization Program, 天涯社区 now has the solar infrastructure capacity to reach carbon-negative emissions. Since 2009, the district has invested in solar energy infrastructure, with solar arrays now installed at 37 sites, collectively generating more than 13.2 megawatts of clean power. These systems have not only reduced greenhouse gas emissions but have also led to significant cost savings.
In addition, the district is rolling out a comprehensive Electrification Program that includes the installation of electric vehicle (EV) charging stations. As part of Southern California Edison鈥檚 Charge Ready School Pilot Program, 天涯社区 has already installed EV charging stations at Irvine and Portola High Schools, available for students, staff, and the broader community. Additionally, the 天涯社区 Grounds Department transitioned 80% of the district's small gas-powered equipment to battery-powered, putting the district on track to achieving 100% battery-powered small grounds equipment by 2026.
Water-Wise Landscaping and Garden Education
Water conservation is also a key pillar of 天涯社区鈥檚 sustainability strategy. Through its Sustainable Landscaping and Garden Program, the district uses drought-tolerant plants, recycled water, and efficient irrigation systems to reduce potable water use. These efforts help save millions of gallons each year while maintaining green and inviting learning environments.
School gardens are another avenue through which sustainability comes to life. Many schools, such as Stone Creek Elementary, use lunchtime food scraps to nourish compost systems that support on-campus gardens. These gardens not only beautify campuses but also serve as hands-on learning tools for students.

Empowering Students Through Education
Education is central to 天涯社区鈥檚 sustainability mission. The district hosts an annual Earth Day Poster or Video Contest that invites PK-12 students to share ideas and solutions through art. This year鈥檚 theme, Our Power, Our Planet: Renewable Energy Now, encourages students to reflect on how renewable energy can impact our earth.
At the high school level, students are also exploring sustainability in the classroom. Last year, Northwood High School introduced a 鈥淐limate Action鈥 elective course, where students examine the environmental impact of food systems and collaborate with university researchers to study school lunch waste and create solutions. In 2024-25, students learned about sustainable building design and the impacts of the Urban Heat Island Effect. Students had the opportunity to share their research to the District's M&O and Facilities departments on the role paint colors play on school facilities and proposed their recommendations for future painting improvements that would reduce the impacts of the Urban Heat Island Effect at Northwood High School.
These initiatives are bolstered by the work of the 天涯社区 Sustainability Steering Committee, an interdepartmental group launched in 2023 to guide and unify sustainability efforts across the district.
