Port Overview¶
The Port of Mobile is a rising Gulf Coast port that has actively taken market share from Houston and New Orleans in recent years. Operated by the Alabama State Port Authority (ASPA) under Director and CEO John C. Driscoll, the port handles approximately 60 million short tons of cargo annually. The Phase IV expansion completed in October 2024 doubled container capacity to approximately 1 million TEUs, with the Mobile Container Terminal operated under concession by APM Terminals and SSA Mobile.
The port's traffic mix includes container, bulk cargo (coal, aggregates, steel), breakbulk, and RoRo, with the Theodore Industrial Canal supporting petrochemical and manufacturing operations. While docked, vessels run auxiliary diesel engines that emit fine particulate matter (PM2.5), nitrogen oxides (NOx), sulfur oxides (SOx), and carbon dioxide (CO₂) directly into adjacent residential neighborhoods — with no state or federal mandate requiring emissions control.
Unlike entrenched petrochemical ports that have reached operational equilibrium, Mobile is mid-expansion. This makes the port a critical test case for emissions assessment methodology where emissions are about to increase — not just persist.
Who Is Affected¶
The communities surrounding the Port of Mobile bear disproportionate environmental burden — led by Africatown, a community of profound historical and cultural significance. Founded by the survivors of the Clotilda, the last known slave ship to enter the United States (1860), Africatown has fought paper mills, chemical plants, and port expansion for over a century. The community's story is documented in the 2022 film Descendant.
| Community | Population | Key Health Burden |
|---|---|---|
| Africatown (Plateau / Magazine Point) | 2,000+ | Founded by Clotilda survivors (1860); adjacent to Alabama Power plant, paper mills, and Theodore canal |
| Prichard | 18,000+ | Historically Black city adjacent to port-related rail and trucking corridors |
| Chickasaw | 6,000+ | Between Mobile and Prichard; port-adjacent residential |
| West Mobile / Maysville | 10,000+ | Downwind of port terminal operations across Mobile River |
| Mobile (citywide) | 184,000 | City-wide exposure to port-related truck and vessel emissions |
Environmental Justice — Africatown
The Africatown story is among the most significant environmental justice narratives in the United States. Residents of Africatown — direct descendants of the last Africans forcibly brought to America aboard the Clotilda — have lived adjacent to the Port of Mobile since 1860. Over the past century, the community has faced paper mills, asphalt plants, chemical facilities, and port expansion — fighting each with limited political capital but extraordinary cultural resilience.
The Port Health Watch assessment recognizes Africatown as a community with agency, history, and deep expertise in documenting the environmental burden it faces. Any engagement is conducted through community-led channels — not extractive data gathering. For reference: Africatown Heritage House (opened 2023) and the Clotilda Descendants Association are primary community institutions.
Community Health Profile¶
CDC PLACES data for Mobile County provides tract-level health estimates for communities surrounding port operations. Port-adjacent tracts — particularly Africatown, Prichard, and Chickasaw — show elevated rates across every measured indicator:
| Health Measure | Port-Adjacent Tracts | Alabama | National |
|---|---|---|---|
| Current asthma among adults | 11.0% | 10.2% | 9.6% |
| COPD among adults | 9.5% | 8.5% | 6.4% |
| Coronary heart disease | 8.5% | 7.8% | 5.7% |
| Depression among adults | 24.5% | 22.5% | 20.5% |
| Obesity among adults | 40.0% | 38.8% | 33.0% |
| Fair or poor self-rated health | 26.0% | 21.5% | 17.5% |
| High blood pressure | 42.0% | 39.5% | 32.5% |
Mobile County port-adjacent tracts exceed state averages across every indicator, with fair/poor self-rated health (+4.5 pp) and high blood pressure (+2.5 pp) showing the sharpest gaps. Alabama's baseline health indicators already rank among the worst in the nation; port-adjacent communities face additional cumulative exposure on top of that baseline.
Health Impact Analysis¶
Using ICCT Port Emissions Screening data and EPA's concentration-response methodology:
| Health Outcome | Current Annual Burden | With At-Berth Capture |
|---|---|---|
| PM2.5 emissions at port (tonnes/yr) | ~150 t (scaled estimate) | 69–99% reduction |
| NOx emissions at port (tonnes/yr) | ~380 t (scaled estimate) | Up to 95% reduction |
| Premature deaths from port PM2.5 | Estimated 7–20/year | 5–19 lives saved/year |
| Cardiovascular & respiratory hospitalizations | Estimated 28–75/year | 20–72 avoided/year |
| Childhood asthma ED visits | Estimated 42–115/year | 29–110 avoided/year |
| Monetized public health benefit (EPA VSL) | $38M+/year | $27–$38M saved/year |
Methodology Note
Emissions estimates scaled from ICCT Port Emissions Screening data and vessel call frequency (Mobile handles ~1,000+ vessel calls annually across container, bulk, RoRo). A comprehensive port-wide emissions inventory has not been published by the Alabama State Port Authority. Ranges reflect this uncertainty and the in-progress nature of Phase IV expansion's emissions impact.
The Regulatory Gap¶
California's CARB At-Berth Regulation has been in effect since 2014 and was authorized by EPA under the Clean Air Act in October 2023. Alabama has not adopted at-berth vessel emission controls, has no equivalent rulemaking underway, and has no state environmental justice framework.
Alabama's environmental regulatory framework — administered through the Alabama Department of Environmental Management (ADEM) — is among the weakest in the country for port-related emissions. Alabama has no state environmental justice legislation, no community air monitoring program equivalent to California's AB 617, and no mandatory port-level emissions reporting. ADEM has legal authority to address port emissions but has not initiated rulemaking.
Pathways to Action
- ASPA voluntary commitment: Alabama State Port Authority could require at-berth controls as a condition of terminal operating agreements with APM Terminals and SSA
- Phase IV expansion conditions: The completed Phase IV terminal expansion creates a near-term window for attaching emissions controls to operating terms
- Federal EPA Clean Ports funding: The $3 billion Clean Ports Program (IRA Section 60102) included Southeast/Gulf awards — disbursement status requires FOIA verification
- Africatown community leadership: Africatown has led decades of successful environmental advocacy. Community-led engagement offers the most credible pathway to port-level change
- Tribal engagement — Poarch Band of Creek Indians: The only federally recognized tribe in Alabama; environmental program interests intersect with Mobile Bay watershed

The Opportunity
At-berth emissions capture at the Port of Mobile could save 5–19 lives per year, prevent up to 72 hospitalizations, and deliver $27–$38 million annually in monetizable health benefits. Mobile's mid-expansion status — with Phase IV just completed — makes the near-term window for attaching emissions controls to operating terms extraordinary. Any engagement is shaped by the leadership and agency of Africatown, Prichard, and the broader port-adjacent communities that have documented the environmental burden of this port for generations.
