1 other organization in the IRS Business Master File lists the same street address. matched by us

We match the street line and ZIP code as the IRS gives them, ignoring case and outer spaces and nothing else, so "AVE" and "AVENUE" count as different streets and this list can miss some. A shared address can mean related organizations or a shared office, but it can also be a registered agent, a mail drop or a service provider holding mail for unrelated clients. It is not, by itself, evidence that two organizations are connected.

Mission and programs · 2025

Mission

The organization's mission is to establish sustainability as an integral part of every child's PreK-12 learning experience. By integrating sustainability across subjects and grades, we can equip students with the knowledge, skills and attitudes that will help lead to a sustainable future for everyone. CELF programs use sustainability as an integrating context for teaching and learning, decision-making, civic engagement, community partnerships and campus practices. The lens of sustainability transforms curriculum, school operations, physical surroundings and school-community activities and fosters the cultivation of engaged citizens.

Activities or mission (Part I)

CELF provides professional learning programs for K-12 teachers and administrators, student experiential learning programs, and curriculum consulting services in order to make sustainability education an integral part of the K-12 learning experience. Our programs for educators, students and community members complement our consulting services by providing varying routes to bringing sustainability into classroom and school culture.

  • Summer Institutes:Multi-day immersive professional development programs for K-12 educators that explore the social, economic, and environmental dimensions of sustainability, and ways of bringing these concepts to life in classrooms through hands-on STEAM activities, case studies, and fieldwork. The Institutes build practical curriculum integration of stewardship perspectives, skills and action to the restoration, rebuilding, and reconnecting of human communities, environmental stewardship and civic life. Participants leave with resources for implementing interdisciplinary, place-based, and inquiry-driven sustainability projects, and receive implementation support from CELF throughout the academic year.

    Expenses $39,662

  • Civic ScienceCivic Science is a semester- or year-long program that engages educators and students in project-based STEAM learning outside of the classroom. Using our Inquiry-to-Action framework, this program trains teachers to engage students in hands-on learning to identify, analyze, and solve real-world environmental issues that impact their school communities. Exploring cross-curricular inquiry pathways such as air and water quality, biodiversity, waste, and infrastructure, students visit local green spaces to collect data, develop action plans, and share findings and solutions with field experts and decision-makers during our culminating annual Student Symposium events.

    Expenses $439,309

  • Professional development and TrainingThe concepts of sustainability are universal, but every district and school starts from a different place in implementing sustainability education. CELF customized professional development (PD) helps schools infuse curriculum and school culture with education for a sustainable future. PD services include: gap analyses of curriculum; on-site Education for Sustainability training and resources (specific to grade level and school or district needs and interests); and review of facilities green infrastructure improvements to help infuse projects into curriculum. Through half-day workshops to multi-year engagements, we provide a framework for integrating sustainability concepts into curricula, community, and culture, helping teachers connect students to place-based learning opportunities in the community, create whole-school action plans, and activate student civic engagement.Green Careers Speaker SeriesAs student interest in sustainability grows, CELF helps students see how their interests and community concerns can be channeled into potential career pathways by connecting them with professionals working in a wide array of sustainability focused careers. CELF connects classrooms directly with industry professionals across sectors to explore opportunities for applying sustainability and systems thinking in their career planning and aspiration.

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all. Showing the 10 most recent; the API carries the rest.

Grants made

No itemized grants to organizations. Schedule I is filed only by organizations that granted more than $5,000 to a recipient, so most filers have none.

Grants received

The 10 largest by cash amount. The API serves every itemized grant.

Other IRS files

Auto-Revocation List

Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.

Publication 78

Listed as of 11 November 2026, under deductibility PC.

These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.
