Priority Ports¶
ICCT-Identified U.S. Ports with Greatest Health Impact Potential¶
The International Council on Clean Transportation screens global ports for the intersection of at-berth vessel emissions volume and surrounding population vulnerability. Port Health Watch focuses on the U.S. ports where health impact intervention would deliver the greatest community benefit.
Selection Criteria¶
Ports are prioritized based on:
- Emissions volume — total PM2.5, NOx, and SOx from ocean-going vessels at berth
- Population exposure — number of residents within 5 km of port terminals
- Environmental justice indicators — income levels, race/ethnicity composition, existing health burden (asthma rates, cardiovascular mortality), cumulative pollution exposure
- Regulatory status — whether the port operates under any mandatory at-berth emissions controls (currently California only)
CARB-Regulated: The Baseline¶
These California ports operate under mandatory CARB At-Berth Regulation — the only at-berth emissions controls in the United States. Their assessments document the proven health benefits of regulation and provide the benchmark for all other ports.
| Port Complex | Est. Criteria Pollutants | Population in Impact Zone | Assessment Status |
|---|---|---|---|
| Los Angeles / Long Beach | ~3,200 t/year (pre-regulation) | 1.5M+ below-median-income | :material-check-circle:{ .tier-critical } Published |
| Oakland | ~440 t/year | 442K below-median-income | :material-check-circle:{ .tier-critical } Published |
Priority 1: Highest Impact¶
These port complexes have the highest combination of emissions volume and vulnerable population exposure outside California.
| Port Complex | Est. Criteria Pollutants | Population in Impact Zone | Assessment Status |
|---|---|---|---|
| New York / New Jersey | ~2,600 t/year | 3.2M below-median-income | :material-check-circle:{ .tier-critical } Published |
Priority 2: High Impact¶
Major port communities with significant emissions burden and no mandatory at-berth controls.
| Port Complex | Est. Criteria Pollutants | Population in Impact Zone | Assessment Status |
|---|---|---|---|
| Houston / Galveston | ~1,000 t/year | 1.5M below-median-income | :material-check-circle:{ .tier-critical } Published |
| New Orleans | ~1,200 t/year | 800K below-median-income | :material-check-circle:{ .tier-critical } Published |
| Seattle / Tacoma | ~900 t/year | 600K below-median-income | :material-check-circle:{ .tier-critical } Published |
| Savannah | ~650 t/year | 200K+ below-median-income | :material-check-circle:{ .tier-critical } Published |
| Baltimore | ~550 t/year | 350K+ below-median-income | :material-check-circle:{ .tier-critical } Published |
Priority 3: Screening Stage¶
Ports with notable emissions or EJ indicators that warrant further analysis.
| Port Complex | Est. Criteria Pollutants | Population in Impact Zone | Assessment Status |
|---|---|---|---|
| Port Everglades | ~400 t/year | 180K+ below-median-income | :material-check-circle:{ .tier-critical } Published |
| Jacksonville | ~350 t/year | 150K+ below-median-income | :material-check-circle:{ .tier-critical } Published |
| Duluth-Superior | ~250 t/year | 55K below-median-income | :material-check-circle:{ .tier-critical } Published |
Commissioning an Assessment¶
Port community organizations, environmental justice coalitions, port authorities, and policymakers can commission site-specific health impact assessments for any U.S. port. See our Services page for scope, deliverables, and pricing, or contact us directly.
Methodology
All port assessments use the same peer-reviewed quantification framework. See our Methodology for complete sourcing and analytical standards.
