A berthed ship is not zero emissions: auxiliary engines and port operations share air with the city.
Even with ships at berth, auxiliary engines and port operations can emit pollutants in densely populated areas. Air maps and residents’ complaints tell a different story from “still ship = zero impact”.
Understanding what changes and what does not helps avoid greenwashing by companies that show only gas ships or single exceptions.
In brief
- Cold ironing and shore power = structural fixes.
- Ask ARPA data and engine hours with transparency.
- Coastal green helps but does not replace port emission cuts.
Ports, cities and health
Compare regional agency data, port basin plans and real investment in cold ironing, shore power and heavy traffic reduction on the waterfront.
Urban green and trees mitigate heat islands and particulates but do not replace cutting emissions at source.
Residents along coasts and port basins live with particulates and noise even when ships are berthed. Compare port plans with air-quality maps — not only LNG ships in photos.
- Ask for transparency on engine hours and fuel type.
- Support green corridors and trees along port areas where technically possible.
- Be wary of “carbon neutral” announcements without verifiable balances.

Frequently asked questions
Do trees solve port pollution?
They help urban wellbeing and some pollutants, but the structural fix remains energy and port regulation.
What to ask the council or port authority?
Shore power plans, engine-hour data, verifiable investments and mitigation of heavy traffic on the waterfront.
