Maritime experts urge tighter monitoring of ship emissions at Malaysian ports

KUALA LUMPUR — Maritime experts and environmental advocates are pressing Malaysian authorities to intensify monitoring of ship emissions at the country's busiest ports, arguing that the pollution impact of commercial vessels has been insufficiently studied and regulated.

The call reflects broader concerns that air quality assessments in port zones may not adequately account for emissions from docked and transiting ships, with some specialists suggesting shipping pollution could be conflated with seasonal transboundary haze from regional forest fires.

Proponents of stricter oversight point to international maritime regulations and successful emission control implementations at other major Asian ports as models. They argue that detailed baseline studies and real-time emission monitoring systems could help authorities better understand local air pollution sources and implement targeted mitigation measures.

Malaysia's port authorities and environmental regulators have not yet responded formally to the recommendations, though port operators in Kuala Lumpur, Port Klang, and other major facilities have previously acknowledged their responsibility in maintaining local air quality standards.
