What Green Science Policy Institute does
Mission
We work at the interface between science and policy to reduce use of harmful chemicals in consumer products and building materials to protect human health and the environment. We motivate and participate in scientific research work with scientists to share their research results with government, standards bodies, and other decision makers and convene diverse high-level stakeholders to effect change in the public interest. Additionally, we educate designers, retailers, manufacturers, and institutional purchasers to empower them to reduce the use of entire classes of chemicals of concern in the products they produce, sell, or buy. Our approach has proven successful at the local, national, and international level for reducing the use of harmful chemicals.
As stated on its FY2025 Form 990.
Programs
REDUCING FLAME RETARDANTS: We continued to reduce the use of unnecessary flame retardants in consumer products. INTERNATIONAL ELECTRONICS: We prevented unnecessary International flammability standards that would lead to the use of flame retardants without providing a fire safety benefit. Our educational work has helped prevent proposed international standards that would have led to the unnecessary use of hundreds of millions of pounds of flame retardants in electronics enclosures. Our team of expert consultants monitor flammability committees to prevent proposals that could lead to the increased use of these harmful chemicals. We are providing input to the European Commission in Brussels and collaborating with the Earth Commission, Environmental Coalition on Standards (ECOS), and progressive electronic manufacturers to use our research results to reduce the use of flame retardants in plastic cases. This will help achieve a toxics-free circular economy and reduce the need to Throw Out Your Black Plastic Spatula.LITHIUM-ION BATTERIES: To reduce the unnecessary use of flame retardants in enclosures around lithium-ion batteries, we are conducting research with Sandia National…
$413,284 spent40% of program spendingREDUCING ANTIMICROBIALS: We increased our focus on quaternary ammonium compounds (QACs), a type of antimicrobials used in consumer disinfectants, cleaning solutions, wipes and personal care products, that are harmful for health and environment, often without a benefit. POLICY CHANGE: 1) We are leading and providing scientific support for California Safer Soap Act (California AB916), first-in the nation legislation to stop the use of harmful and ineffective antimicrobials in soap and body wash. The bill, co-sponsored by Womens Voices for the Earth and Children Now, has passed the Environment and Toxic Materials Committee of the California Assembly. 2) We are providing scientific support and outreach to the UC Berkeley Law Clinic and Breast Cancer Prevention Partners (BCPP), for an antimicrobial consumer deception bill that will be introduced in the California Senate in 2026.MANUFACTURER EDUCATION: In October, we organized a well-received Antimicrobial Information Exchange meeting, which brought together representatives from most of the major soap and cleaning product brands that use antimicrobials, scientists who shared their research and government agencies who are beginning to…
$413,284 spent40% of program spendingSIX CLASSES ACCOMPLISHMENTS: MEETINGS:1) We met with policymakers in Congress and agencies in Washington, DC. We educated Senate and House staff from both sides of the aisle on the class concept and the potential for harm of flame retardants and antimicrobials. During our meetings, we encouraged policy change, letters, appropriations report language, and other actions to update regulations to reduce toxic chemical exposures. 2) Held our Six Classes Toxic Reduction retreat with two dozen enthusiastic colleagues from the business, academic, government, and nonprofit sectors to discuss and develop plans for reducing the use of harmful chemicals with a focus on antimicrobials.COMMUNICATIONS: 1) Our monthly newsletter subscribers increased from 18,000 readers in 2024 to over 24,000 with a 50% open rate. Positive feedback includes Wellington Labs telling us our newsletters help them prioritize chemicals for their testing business and their LinkedIn post: Arlene's ongoing commitment to sharing environmental issues in a balanced, scientifically-sound manner helps broaden awareness across the field. 2) Arlene Blum presented on Tackling Toxics in Plastics during the Great Pacific Garbage…
$154,981 spent15% of program spendingREDUCING PFAS: We continued to support our partners with scientific expertise:SCIENTIST CALLS: Led monthly PFAS Science and Policy calls that bring together scientists worldwide. In 2025, over 200 scientists were participating. The calls served as a basis for numerous scientific publications and policy advances.PFAS WEBSITE: To share knowledge more broadly, we continue PFAS Central, a website updated weekly with news, science, policy, jobs, and events. At the request of communities dealing with PFAS contaminated drinking water, this website contains a list of PFAS-free products.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2022 to 2023, from $3.0M to $3.6M (+20%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2021 7%. Grants only. Government contracts and fees sit inside program revenue.
66% of GREEN SCIENCE POLICY INSTITUTE’s revenue is contributions — about as donation-reliant as the typical peer (88% for the typical peer).

Who funds it, year by year
2017 → 2023: the base narrowed from 10 funders to 9 funders, grant income rose $237k → $431k.
10 of 30 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 43% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of GREEN SCIENCE POLICY INSTITUTE’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
GREEN SCIENCE POLICY INSTITUTE has a broad base — no single funder exceeds 29% of grant income, and it takes 4 funders to reach half.
the vertical line marks half of all grant income — 4 funders to its left
44% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund GREEN SCIENCE POLICY INSTITUTE.
Largest funder’s share by year: 2017 30% · 2018 26% · 2019 28% · 2020 14% · 2021 72% · 2022 25% · 2023 35% — growing more concentrated.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
55% of GREEN SCIENCE POLICY INSTITUTE's funders are still giving 3 years after their first grant; 63% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
GREEN SCIENCE POLICY INSTITUTE draws 59% of its grant income from funders outside California, across 10 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.7M arriving through sponsors registered in 10 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Against its field
GREEN SCIENCE POLICY INSTITUTE holds deeper cash reserves than three-quarters of the 1,074 environment nonprofits its size.
