Clean Fuels Alliance America (Clean Fuels) serves as the trade association representing biodiesel, renewable diesel, and SAF producers. Clean Fuels works to advance the use of biodiesel, renewable diesel, and sustainable aviation fuel as practical tools to improve air quality and protect public health—particularly in communities that experience a disproportionate share of pollution exposure.
That mission is backed by a growing body of data. Clean Fuels recently commissioned a comprehensive Health Benefits Study conducted by Trinity Consultants, with support from industry partners, to better understand how biodiesel impacts air quality and health outcomes at the community level. The findings reinforce what many fleets and communities already experience firsthand: biodiesel delivers immediate, local health benefits, especially in areas burdened by diesel emissions.
What the Health Benefits Study Found
The study evaluated 45 high-risk communities across the United States, focusing on two sectors that are traditionally difficult to decarbonize—legacy heavy-duty transportation and residential heating. Using EPA-approved air dispersion models and established health-risk valuation tools, researchers analyzed the impact of replacing petroleum diesel with 100% biodiesel (B100).
Across the study areas, switching to B100 resulted in annual public health benefits that included:
- Nearly 457,000 fewer asthma cases
- Almost 177,000 fewer lost work and school days
- More than 1,100 premature deaths prevented
- Over $9.6 billion in avoided health costs
- A 45% reduction in cancer risk from legacy heavy-duty vehicles and an 86% reduction from biodiesel use in home heating applications
These benefits were driven largely by reductions in fine particulate matter (PM₂.₅) and toxic air pollutants—emissions closely linked to asthma, cardiovascular disease, and cancer risk.
Detroit: A Closer Look at Emissions and Health
Detroit was one of the communities included in the study, reflecting its long-standing air quality challenges and its proximity to freight corridors, industrial operations, and marine activity. The modeling showed that biodiesel use in Detroit would significantly reduce localized exposure to diesel exhaust pollutants, particularly in Environmental Justice communities located near transportation and port infrastructure.
In Detroit, the study found that biodiesel adoption led to:
- Meaningful reductions in cancer risk from diesel exhaust exposure
- Fewer asthma cases tied to transportation emissions
- Lower incidence of premature mortality associated with fine particulate pollution
These findings are especially relevant for port-adjacent neighborhoods, where heavy-duty trucks, marine vessels, and cargo-handling equipment often operate in close proximity to homes, schools, and community centers.
Connecting the Data to Action at the Port of Detroit
The study’s findings align closely with ongoing work at the Port of Detroit, where stakeholders are actively exploring near-term strategies to reduce emissions without compromising reliability or economic activity. Marine and freight operations are among the most challenging sectors to decarbonize, making drop-in solutions like biodiesel especially valuable.
The Michigan Advanced Biofuels Coalition (MiABC) is working collaboratively with the Port of Detroit, SDEV, and other public- and private-sector partners to advance the use of biodiesel and other biobased fuels across port-related operations. These efforts focus on reducing particulate matter, improving air quality for nearby communities, and delivering measurable health benefits today—using fuels that are already compatible with existing equipment.
By supporting biodiesel use in drayage trucks, port vehicles, and other diesel-dependent applications, these partnerships help translate the Health Benefits Study’s findings into real-world emissions reductions where they matter most.
A Practical Path Forward for Health and Climate
The Clean Fuels Health Benefits Study underscores a critical point: renewable fuels are not a future-only solution. They are delivering tangible environmental and public health improvements right now, particularly in communities facing the highest pollution burdens.
For Detroit and other port cities, biodiesel offers an immediate, scalable opportunity to reduce emissions while longer-term technologies continue to develop. Through collaboration with partners like Clean Fuels Alliance America, the Port of Detroit, SDEV, and regional stakeholders, MiABC is helping ensure that data-driven solutions translate into cleaner air, healthier communities, and a more resilient transportation system across Michigan.
