Summary

What do they do? Coalition for Clean Air works to reduce pollution from transportation and other sources across California. It advocates for clean-air protections and helps communities monitor air quality. Our estimate examines one part of its work: advocacy that could preserve controls on emissions from ships while they are at berth.

Why we’re interested in this organization:

  • Cleaner air can prevent premature deaths and reduce illness, and CARB has modeled the benefits of this specific regulation.

  • The organization is actively working on the policy issue rather than relying solely on a historical campaign.

  • Three original annual returns make the organization’s operating scale and spending inspectable.

Our main reservations:

  • The advocacy allocation, donor additionality and change in legal-enforceability probability are judgments, not measured donation effects.

  • The historical regulatory projection is not a measured remaining-year trajectory; physical rollback, current legal status and survival prognosis remain uncertain.

  • Private savings, work effects and compliance costs have unknown net incidence; regional splits and other organizational pathways remain unquantified.

What do you get for your dollar? $1.0M per DALY in California. DALY is our one-year comparison unit. QALY-based health gains and income-welfare equivalents retain their original assumptions; they are not measured clinical DALYs. Partial conditional California at-berth policy health plus household-resource planning estimate.

Prospective prevented premature-death event equivalents from regulatory projections; separate nonfatal baseline-alive household cash/work and consumer-cost diagnostics. No baseline survivor wages or public payer savings.

1. What do they do?

Coalition for Clean Air is a California nonprofit, EIN 23-7120567, working on air-quality policy, transportation pollution, community monitoring and education. Its official donation form identifies the same legal recipient. Current work Donation form

This estimate focuses on advocacy to preserve enforceable emissions controls for ships at berth. Shore power and other controls reduce pollution while ships are in port; preserving the rule could protect the benefit of those controls. CCA’s participation does not establish that its work changes the legal outcome. The comparison is additional CCA work versus existing advocacy, litigation, infrastructure and earlier controls continuing without a new donation.

The estimate does not credit a new gift with already installed YMCA filters, previously signed laws or historical emissions reductions. Other CCA programs may matter, but their effects are not quantified in this partial model.

2. Monitoring and information sharing

AirAware is an existing EPA-funded partnership with TD Enviro, IQAir and three Los Angeles-area YMCA sites, not three donor-created sites. Monitoring and installed filtration support a mechanism but do not establish occupied person-hours or a causal clinical effect. Project reports Already funded installations and adopted policy remain in the baseline. Future maintenance may be valuable, but no priced unfunded schedule is established. Source receipts and the full clock-anomaly exclusion are preserved in the dated evidence packet.

3. Qualitative assessment

We see a plausible connection between the organization’s policy work and a meaningful health outcome: reducing exposure to pollution from ships. CCA’s September 24, 2026 campaign describes defending California’s at-berth waiver after House action. The subsequent legislative disposition was not freshly confirmed in this review; the model is conditional on a remaining legal and implementation margin. CCA campaign

CARB’s original final response projects 230 fewer premature deaths, 72 hospital admissions and 116 emergency visits statewide during 2021–2032 from the expanded rule. These are modeled regulatory outcomes, not observed CCA outcomes. We use the projected totals as a scale anchor, not as proof of the remaining benefit in 2026. The complete PDF was retrieved and hashed; the decisive passage was read through primary-domain indexed extraction, not a new full-document numerical audit. CARB final response

The key unanswered question is how much an additional donation changes the outcome beyond other advocates and existing funding. Neither an op-ed nor a deficit answers it. We also lack a remaining-year emissions profile and beneficiary age distribution. Those gaps make this an exploratory comparison, not a source-vetted giving recommendation or complete estimate of the organization’s expected value.

4. What do you get for your dollar?

Our conditional estimate is approximately $1.0M per DALY: one modeled equivalent year. It prices a small change in the likelihood of preserving at-berth emissions controls—not the purchase of a guaranteed health outcome.

We think this pathway could be valuable because preserving a regulation can affect many ships and nearby residents. CARB projects fewer premature deaths and nonfatal illnesses from the expanded rule. The economic question is whether a modest amount of additional advocacy changes enforceability enough to justify its cost. Our estimate explicitly includes donor additionality and the physical benefit that would remain even if legal protections were lost.

For an illustrative $10,000 normalization, we allocate 40% to this policy margin and divide by the full FY2025 gross recipient expense of $2,494,912. We assume 50% funding additionality and a five-percentage-point net legal response per whole-annual-budget-equivalent of added policy effort. The resulting probability increment is 0.00004008, or about 0.004 percentage points—not a 5% success probability for this donation. These are judgments, not measured staffing costs or causal policy influence. The cost includes the recipient’s shared administration, fundraising and event expenses once.

Conditional on a legal change, we assume half the projected physical benefit is at stake: existing shore-power infrastructure, earlier controls and voluntary compliance may preserve some reductions. That physical-realization assumption is separate from the legal probability, which already accounts for other actors and litigation. We assume a five-year future benefit window beginning after three months. The historical 230/12 death-event profile is reused as a flat future planning assumption; no 2021–2026 benefit is credited retrospectively.

Each prevented premature death receives a finite survival valuation: utility 0.75, annual competing mortality hazard 0.035 and a ten-year tail, discounted at 3%. This produces about 5.53 health years per event before the event-date discount. These prognosis assumptions are unvalidated, not ten guaranteed years or a CARB-derived life table. We do not multiply CARB’s mortality projection by another pollutant risk estimate. The central yields 0.01 health years per $10,000.

Income and household resources: the central resource contribution is zero because the net household incidence and sign are not established. That is not evidence of no economic benefit. The model separately tests baseline-alive households’ avoided private payments, net work gains and compliance costs. It excludes gross insurer/public medical savings, construction spending and baseline earnings of extra survivors. Positive and negative resource cases leave the health cohort unchanged.

In nonfatal-event scenarios, a judgmental 25% of admissions or emergency visits become distinct household resource units, with net receipts of $100 per admission and $25 per emergency visit—or signed losses. These are not observed bills or wages. Repeated households must be combined before logarithmic valuation; event receipts occur once rather than repeating over the mortality survival tail. Other diagnostic cases test annual productivity gains and consumer compliance costs only during the policy-active window. Gift-induced engagement costs remain possible even if advocacy fails, but unchanged baseline activity is not charged. Income comparison method

The historical $334K illustration used a generic population and pollution change rather than this named regulatory pathway. It remains preserved for comparison; the new calculation is not a residual obtained by subtracting income from the old total. The exact current price is $1.0M versus $334K historically. This change is a model revision, not measured organizational deterioration. See the expandable model for all 29 scenarios, including different policy responses, time windows, survival tails, signed resources, nulls and adverse mortality.

Public and private implementation costs are not fully priced here. The result is a partial donor comparison, not a complete societal cost-effectiveness ratio or a lower bound.

Counterfactual: Legal enforceability with/without incremental CCA advocacy, net of other actors/litigation. Conditional physical exposure realization separately includes installed infrastructure, earlier controls and voluntary operation. Already realized/adopted benefits remain baseline.

Attribution: Funding additionality .5, policyShare .4 and response .05 are distinct judgments. response is absolute net legal probability per whole-annual-budget effort, not measured outcome; realization .5 is physical exposure, not second legal probability. Shared portfolio assignment applies once to policy benefits/resources, not independently induced harms.

Conditional partial planning central, not measured donor EV or complete portfolio/lower bound. No empirical scenario weights. Current legal status, donor tranche, remaining exposure, prognosis and private-resource incidence uncertain.

Sensitivity

  • 29 unweighted finite cases include response, future profiles, funding/nulls, physical realization,5/20/30-year prognosis, signed policy mortality, net private resources, annual community productivity/compliance costs and independently induced failed-access burden.
  • Negative survivor utility is a mathematical quality-of-survival diagnostic, not shorthand for extra deaths; signed annualDeaths case represents adverse mortality.
  • No case establishes a priced donor tranche or identifies regional reach; preserve zero/no-change and signed results without positive-price coercion.

Unresolved inputs

  • Current legal disposition and actual gift-induced advocacy work/capacity.
  • Remaining-year rule-specific exposure trajectory and counterfactual voluntary/earlier-control emissions.
  • Age-specific post-event prognosis and net private household resource incidence/deduplication.
  • Incremental public/private implementation inputs and omitted portfolio mechanisms.

Health and income breakdown

5. Funding and previous grants

The latest three original returns reconcile comparable gross expenses of $1,472,176 in FY2023, $2,162,329 in FY2024 and $2,494,912 in FY2025, averaging $2,043,139. This includes Part IX, separately netted event costs and applicable donated services without adding those services twice to Schedule D totals. FY2023 FY2024 FY2025

FY2025 Part IX reports $1,479,082 for programs, $647,639 for management and $326,174 for fundraising. Revenue was $2,149,048, with a $303,847 deficit. Assets of $1,518,894, liabilities of $405,280 and net assets of $1,113,614 are June 30, 2025 balances, not current available cash or evidence of a funding gap. Schedule D financial reconciliation is available; an independent CPA opinion and control findings were not separately verified.

The organization’s current campaign and donation route support ongoing operations, but no priced marginal staffing or consultant tranche was established. The model’s $100,000 exploratory gift cap is a numerical domain, not verified funding room. A funding decision needs a current work plan, alternative funding, staff availability and an explanation of what changes without the gift. The existing EPA-funded AirAware project is baseline activity, not new donor-created capacity.
