Ships use diesel powered electrical generators on board for lighting, air conditioning, control systems, fuel and water systems, bow thrusters and cargo handling.

The pollutants emitted from ships like nitrogen oxide (NOX), sulfur dioxide (SO2), hydrocarbons (HC), and around the port area, ship’s emissions may give negative health effects including asthma, other respiratory diseases, cardiovascular disease, lung cancer, and premature death.

Johor Port Authority (JPA), collaborated with UTM researchers develop an online system named Ship Emission Management System (SEMS) for accounting the shipping emissions and analyse the emissions improvement measures in ports.
