Mission and programs · 2024

Mission

To cultivate the success and enduring impact of mission-driven entrepreneurs emerging from University programs whose food systems innovations will positively transform culture, community, climate, health and social equity.

  • In 2024, Plant Futures advanced its mission to equip students to become the next generation of ethical leaders, systems thinkers, and effective advocates for a plant-centric future. Plant Futures hosted the Challenge Lab course at UC Berkeley, partnering with over 10 Lab businesses; 99% of students reported that the Lab helped them gain multiple professional contacts in the plant-based food and ag sector. Plant Futures also received a grant to launch a new three-unit, cross-campus course by Spring 2025. Plant Futures chapters expanded from 44 to 80 campus chapters, and engaged over 2,100 active student chapter members from diverse racial, geographic, and academic backgrounds. Other student support included, but is not limited to, hosting a Career and Leadership Series that engaged 250 students and launching a Mentorship Program that connected 40 students with experienced professionals from leading sustainable enterprises. In February, Plant Futures hosted the Plant Futures Fest with over 500 attendees from around the globe to celebrate the future of plant-forward food systems. Plant Futures continues to explore and grow its international presence, particularly in Mexico. In 2024, Plant Futures hosted a leadership networking event and began exploring chapter growth across Mexico. Plant Futures was honored as a finalist for the Program of the Year award at the Vegan Women Summit.

FARMpreneurs also hosted a community event with approximately 100 attendees including farmers, funders, and local food system leaders to connect influential stakeholders to the FARMpreneurs goal to enhance the profitability of community-based farmers.

  • Climate Farm School joined Ideagarden Institute in spring 2024. In 2024, Climate Farm School engaged 125 participants in 11 on-farm courses. The program engaged diverse professionals including physicians, educators, entrepreneurs, farmers, and policymakers. Climate Farm School continued to grow its specialized course programming, including a course for 18 farm-based educators in partnership with Shelburne Farms and the Farm-Based Education Network and a professional development workshop for 15 San Francisco Unified School District School Nutrition Services participants. The program directed $95,000 to regenerative farmers for education, lodging, and food procurement, and featured 15 farmer guest speakers across Climate Farm School programming. The program's alumni network now exceeds 200 individuals connected through email and WhatsApp groups, and approximately 40 alumni successfully transitioned to food and farming system roles after a Climate Farm School course. The program participated in multiple conferences with a speaking opportunity at TEDxBoston, sharing the importance of connecting individuals with on-farm, in the soil, experiences.

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.

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 13 October 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.
