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:

  1. Emissions volume — total PM2.5, NOx, and SOx from ocean-going vessels at berth
  2. Population exposure — number of residents within 5 km of port terminals
  3. Environmental justice indicators — income levels, race/ethnicity composition, existing health burden (asthma rates, cardiovascular mortality), cumulative pollution exposure
  4. 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.
