Air Quality & Emissions¶
Brunswick Emissions Analysis¶
The air quality analysis for the Port of Brunswick examines emissions from at-berth vessel operations — predominantly RoRo (roll-on/roll-off) auto and equipment carriers — at Colonel's Island Terminal and Mayor's Point Terminal, and their impact on surrounding Brunswick and Glynn County communities.
← Back to Port of Brunswick Overview
RoRo-Dominant Traffic Profile
The Port of Brunswick is the largest U.S. port for automobile, heavy machinery, and farm equipment imports and exports. RoRo vessels have shorter at-berth times than containers (typically 12–24 hours vs 24–48) but concentrated per-call emissions during loading/unloading operations. RoRo was the original target vessel class for CARB-certified barge-mounted emissions capture — making Brunswick a strong candidate for early deployment outside California.

Monitoring Stations¶
GA EPD operates continuous air quality monitoring around Brunswick:
| Station | Location | Proximity to Port | Pollutants | Operator |
|---|---|---|---|---|
| Brunswick (Gloucester Street) | Central Brunswick | ~2 miles | PM2.5, O₃ | GA EPD |
| Brunswick (Newcastle Street) | Port-adjacent | < 1 mile | PM2.5 | GA EPD |
| St. Simons Island | Golden Isles | ~7 miles | O₃ | GA EPD |
GA EPD's Brunswick monitoring network is less dense than peer state networks. Community-led monitoring infrastructure is limited. FOIA requests for unpublished GA EPD internal monitoring data are a priority.
