I submit this comment in support of Chapter
173-423 WAC, the Clean Vehicles Program, from the perspective of a
practitioner's experience in climate policy, land-use impacts, and local
ecological systems in Washington State.

cost-benefit framework, stricter vehicle emission and zero-emission vehicle
standards represent the most economically responsible path forward for the
state. Transportation remains Washington’s single largest source of greenhouse
gas emissions and a major contributor to criteria air pollutants that directly
affect public health. The economic costs of these emissions are already borne
by Washington residents through increased healthcare expenditures, lost
productivity, degraded ecosystems, and mounting climate adaptation costs. These
are not speculative impacts; they are ongoing fiscal liabilities that continue
to grow without preventive action.
The Clean Vehicles Program appropriately
shifts the economic analysis upstream, where costs are lowest and benefits are
greatest. Reductions in nitrogen oxides, particulate matter, and ozone
precursors yield immediate and measurable public health benefits, including
fewer asthma attacks, reduced cardiovascular disease, lower hospitalization
rates, and improved worker productivity. Peer-reviewed studies consistently
show that the monetized health benefits of cleaner vehicle standards exceed
compliance costs, often by multiples, particularly in population centers and
over multi-decade time horizons.
From a climate risk perspective, the program
functions as a cost-containment strategy. Washington is already experiencing
escalating expenditures related to wildfire response, smoke-related public
health emergencies, flood damage, drought impacts on agriculture and
hydropower, and infrastructure stress. Each incremental reduction in vehicle
emissions reduces the probability and severity of future losses that would
otherwise require taxpayer-funded recovery. Delaying emissions reductions
increases long-term costs and narrows future policy flexibility.
The Clean Vehicles Program also protects
critical ecosystem services that underpin Washington’s economy. Air quality,
snowpack stability, forest health, salmon recovery, and marine ecosystem
resilience are all sensitive to transportation-related emissions and climate
warming. Degradation of these systems transfers costs from natural processes to
engineered solutions and emergency response, which are consistently more
expensive and less reliable.
Preventing harm is fiscally preferable to
attempting restoration after damage has occurred. Concerns regarding near-term
vehicle costs must be evaluated against total cost of ownership and long-term
household economic stability. Zero-emission vehicles offer lower operating and
maintenance costs, reduced exposure to fuel price volatility, and increased
energy security. Over time, these savings disproportionately benefit low- and
moderate-income households when paired with appropriate infrastructure and incentive
deployment, reducing—not increasing—economic inequality.
Importantly, alignment with California
standards under Chapter 173-423 WAC provides regulatory certainty and market
scale. Harmonization reduces compliance complexity for manufacturers,
accelerates technology deployment, and lowers per-unit costs over time.
Regulatory certainty is itself an economic
benefit, enabling long-term planning and investment while avoiding the far
greater costs associated with delayed or fragmented action.
In summary, the Clean Vehicles Program
represents prudent economic governance. When health impacts, climate risk,
ecosystem services, and market stability are properly accounted for, stricter
vehicle emission standards minimize long-term public costs and protect
Washington’s economic resilience. Weakening or delaying these standards would
externalize known costs onto future budgets, ratepayers, and communities. For
these reasons, I strongly support Chapter 173-423 WAC and urge the Department
of Ecology to maintain and fully implement the Clean Vehicles Program as a
cornerstone of Washington’s long-term economic, public health, and climate
strategy.
