Founder’s Message

With the climate crisis wreaking havoc, especially on those least responsible for it, I’m grateful to have been working with the Ten Strands team for ten years. Never before has an equitable high-quality environment-based education been more important. In our complex world, an educated population is crucial in the fight against climate change. Ten Strands’ mission supports the next generation of learners and leaders to deeply understand and connect to the natural world around them, and be active in adapting and mitigating climate change impacts. Ten Strands is proud to be at the forefront of the environmental literacy and sustainable and climate-resilient schools movement—collaborating with our partners on innovative programs, advancing education policy changes, building a dedicated donor community, and advocating for state funding. We are deeply grateful for our partners, funders, and leaders in the public sector, including the State Board of Education and the California Department of Education for advancing climate change education and action. Much work lies ahead, and with the continued support from our funders, we will get there.

With deep appreciation,

Will Parish, Founder and Board Chair

Will Parish

CEO Welcome

Dear Friends,

Twenty years ago, California, ahead of most other states, passed legislation to integrate environmental principles and concepts into core academic subjects. Ten years later, Ten Strands launched to catalyze a movement to support teachers, administrators, and community-based partners to advance environmental literacy and build on that early legislation. You can read about our first ten years here.

Last year, we expanded our team and partners to work with the education system to support ecologically-resilient school grounds and school building decarbonization efforts. In July, we launched our first direct-to-youth initiative to work with high school students on foundational knowledge and skill-building activities related to environmental and climate action.

Focusing on teaching and learning—inside and outside of the classroom—as well as school grounds and buildings is our urgent response to the climate crisis. We adopted a whole school sustainability approach to meet county, district, and site leaders where they are and work together to meet their goals. We understand the complexities of getting started across and within the largest school system in the country.

From the beginning, partnerships have been at the heart of our model. Our partnerships are successful because we value equity, innovation, shared leadership, care and connection, transparency, and persistence. You can read more about our values here.

Thank you for reading the progress of our work in this year’s annual report. We look forward to being in community with you as we celebrate more successes in the year ahead.

With immense gratitude,

Karen Cowe, CEO

Thought Leadership

Ten Strands expanded its capacity in 2022-23 to advance the environmental literacy of K–12 students by welcoming new staff members to the team. We also organized and spoke at over twenty conferences, events, and webinars, highlighting our influence and expertise on environmental and climate change literacy efforts in California.

Last summer, Ten Strands announced the addition of new director of curriculum Roni Jones, who is leading the development of California’s new Climate Change and Environmental Justice Program (CCEJP). Roni brings to Ten Strands over three decades of success in leading educational systems change.

Andra Yeghoian

In August, Ten Strands also welcomed Andra Yeghoian as our new chief innovation officer, bolstering our team and the work of our organization and sparking environmental literacy with her whole systems approach. Andra brings her experience of working at the county office of education level, where she directly influenced twenty-three school districts through her programs. She is now focused on taking her programs to scale across the state. Andra has spoken at over a dozen events this last year.

In early spring, Karen Cowe, Ten Strands CEO was invited to present strategies toward advancing environmental and climate literacy at the annual general membership meeting of the California County Superintendents. Working closely with San Mateo’s superintendent Nancy Magee, Karen shared our vision for how to scale climate change education and environmental literacy across fifty-eight counties.

A Year of Powerful Partnership to Advance Environmental Literacy

Climate Change and Environmental Justice Program

A collaboration between Ten Strands, the San Mateo County Office of Education, the California Department of Education, and community- and student-centered organizations who have come together to create K–12 open education resources focused on climate change and environmental justice.

We believe in empowering students to be environmentally literate, engaged citizens who can act for the well-being of their family, broader community, and environment. Our focus is to support teachers with age-appropriate instructional materials on local environmental challenges, sparking students’ curiosity about how their community is affected and possible solutions. This year, the writing teams—made up of community- and student-centered organizations with diverse experiences writing curriculum and providing professional learning—have made significant progress toward developing the curricular units. Lesson plans continue to be drafted under the guidance of Ten Strands, BSCS Science Learning, and the Climate Collective. Read more about the curricular resources here.

Supporting Teachers with Professional Learning

We supported Senator Ben Allen’s budget request for the state to allocate an additional $10 million to provide sufficient professional learning support for teachers, and build upon and leverage the initial investment in curricular resource development. Through this campaign, we built a broad coalition of 250 supporters, positioning us for a successful campaign next year. 400 teachers have already expressed interest in contributing to and using the curriculum. Read our response to the California State Budget this year.

Empowering Community Voices

Our writing teams have each published their story on how they hope to empower young people to understand climate change and environmental justice, leading to action in their communities. Collectively their stories have been viewed over a 1000 times.

California Environmental Literacy Initiative

A collective action network seeking to ensure access to high-quality environment-based learning for all California’s TK–12 students.

We believe in the power of systems change as a lever to ensure that all students have access to high-quality environment-based learning. This year—with a membership made up of educators, governmental and non-governmental agencies, scientists, sustainability professionals, and individuals with expertise on the environment and systems change—CAELI completed its first full season under the leadership of Andra Yeghoian as project director and the new Theory of Action. Andra replaced Ten Strands’ CEO, Karen Cowe, who was in this role for the first eight years of the initiative. Learn more about how the hubs promote student learning in our monthly newsletters.

Joining Juanita Chan-Roden, we also welcomed CAELI’s newest co-chair, executive director of the Association for Environmental and Outdoor Education Estrella Risinger, and said goodbye to departing co-chair Craig Strang. We thank Karen and Craig for their service. Read more about the leadership transition that took place in June 2023 here.

Environmental and Climate Change Literacy Projects

A collaborative effort between Ten Strands and the UC and CSU schools of education to educate the more than 400,000+ graduating high school students per year in California to become literate in climate change and environmental justice issues and solutions.

Many of California’s 5.8 million public school students enter adulthood with inadequate climate and environmental justice literacy. Ten Strands partners with ECCLPs to build pre-service and in-service educator capacity to activate and empower students to be literate in climate and environmental justice issues. Last fall, approximately 400 climate activists gathered at UC Irvine to relaunch ECCLPs and recommit to the fight for environmental literacy in PK–12 education systems across California. Read about the event here.

Leveraging Higher Education

In the spring of 2023, ECCLPs launched its first campus hub at California State University, Dominguez Hills, as well as three working committees focused on Research, PK–12 Teaching and Learning, and Community-Based Partnerships.


Community Leadership

ECCLPs inaugural executive director Kelley Lê shared her insights on the work advanced in the last year, featuring the voices of each ECCLPs committee lead. Learn about each of the committees and their leads here.

Outdoor Learning Initiatives

Creating safe and healthy outdoor learning spaces at school sites, strategies for teaching and learning outdoors, and opportunities for field based residential and day-time outdoor learning are at the heart of our Outdoor Learning Initiatives.

Schoolyard forests shade and protect TK–12 students from extreme heat and rising temperatures due to climate change. The California Schoolyard Forest System℠—our partnership with Green Schoolyards America—launched a free online resource library providing practical resources to schools and districts as they plan, develop, use, and manage schoolyard forests.

In March, Ten Strands CEO Karen Cowe spoke at the first of a five-part webinar series about the Living Schoolyards Act. We continue to advocate and highlight the importance of transforming the spaces in which children play everyday—schoolyards.

Outdoor Learning Initiaves

Beyond California

We supported the Living Schoolyards Act, a groundbreaking bill that directs federal resources to convert schoolyards into living and verdant spaces to protect students from extreme heat, nurture their curiosity and sense of wonder, invite learning, imagination, and play, to promote environmental stewardship.

Outdoor Learning Initiatives - Advocacy

Environmental Literacy in Every Subject

Ten Strands’ director of strategic partnerships, Amy Frame, authored a new framework for the Resource Library that identifies how to use schoolyard forests to support academics across grades and subjects.

Sustainable and Climate-Ready Schools Initiative

A partnership with UndauntedK12 to ensure school infrastructure and grounds are resilient and support student health, safety, learning, play, and development in a time of rapidly increasing extreme weather.

In this era of rapid climate change, we need to ensure that the buildings and grounds of California’s public schools are developed as sites of resilience and sustainability. In 2022, we partnered with UndauntedK12 to launch the California Climate Ready Schools Coalition, a group of thirty diverse organizations representing various perspectives on education and climate policy collaborating to support climate-ready schools for California’s most vulnerable students.

In the spring of 2023, the Climate Ready Schools Coalition released Climate Resilient California Schools: A Call to Action, the first comprehensive report on climate-driven impacts on children in California. The report presents evidence-based recommendations, including a master plan for California’s schools that centers climate resilience within the 21st-century mission of public schools, securing students’ health, safety, and learning through extreme weather events, environmental hazards, and other disruptions.

In The News

The Coalition’s report, Climate Resilient California Schools: A Call to Action, was co-authored by Ten Strands, UndauntedK12, Stanford University’s Sean N. Parker Center for Allergy and Asthma Research, the Action Lab for Planetary Health at Stanford Medicine’s Center for Innovation in Global Health, and the University of California at Berkeley’s Center for Cities + Schools. The report was featured in the Los Angeles Times, EdSource, EducationWeek, The 19th, and Stanford Medicine Magazine.

Protecting Public Schools

We supported Senate Bill 394, which requires the creation of a master plan for healthy, sustainable, and climate-resilient California schools. In April, Andra Yeghoian moderated a policy forum on how schools can tackle the climate crisis and the path ahead to achieve climate-resilient schools. Although not signed into legislation this year, the movement built a strong coalition. We will continue pushing our state to invest in building school resiliency and preparedness for climate change to protect student health and well-being.

Data Initiative for Environmental and Climate Action in California’s TK–12 Schools

A partnership with UndauntedK12 to provide interactive data sets that can be used to catalyze change for environmental and climate literacy and action efforts in California TK–12 schools.

This Data Initiative responds to the need for an equity-informed, data-driven approach that prioritizes underserved communities and addresses environmental injustices. This year, the Data Initiative has made significant progress in advancing a statewide analysis of:

  • school districts in counties taking the most and least amount of environmental and climate action;
  • the California Green Ribbon program since 2014; and
  • the extent to which the twenty-five largest school districts in California have invested in environmental and climate action.

Leveraging Data for Impact

The Data Initiative identifies key demographic indicators related to need, as well as tracks readiness and progress on high impact leverage points for change such as school board policies, bond measures, and investments in environmental and climate initiatives and staff to lead these initiatives.

Identifying Opportunities

The Data Initiative launched a website that includes the start of the interactive data sets that can support scaling implementation of environmental and climate action in California’s schools by using an equity-informed and data-driven approach.

Looking Ahead

California Youth Climate Policy Leadership Program

In May, we launched a new statewide youth program designed to empower high school students to enact real change in their school or district. Facilitated in partnership between Ten Strands, the Sierra Club, and UndauntedK12, we are supporting forty-five tenth-through-twelfth-grade students to take climate action into their own hands. Throughout the program, students focus on foundational knowledge and skill-building activities related to environmental and climate action. Students will then apply their knowledge and skills on leading an advocacy campaign that passes climate policies (or builds on existing policies) in their school or district.

Technical Assistance

Ten Strands has been supporting local education agencies (LEAs—county offices of education and school districts), schools, organizations, and individuals with direct services on environmental and climate literacy and action. In the coming year, we look forward to expanding our capacity to support schools in integrating environmental and climate literacy as well as action on sustainable and climate-resilient schools into TK–12 education across the whole system.

Stories of Impact

Featured in our bi-monthly newsletters, this year we’ve helped uplift twenty-four stories about environmental and climate literacy efforts in California.

We believe that young people have valuable perspectives and a critical role in shaping our society and our world. Our Youth Voices series is a platform for young people to drive dialogue and create positive change.
