“…In order to reduce the emission of harbor pollutants, the International Maritime Organization (IMO) has already put new regulatory standards into legislation (Paul et al, 2012;Coppola et al, 2016). At present, measures to reduce ship pollutant emissions include the use of low-sulfur fuel or Liquefied Natural Gas (LNG) as auxiliary engine fuel, the use of scrubbers, the use of shore-to-ship power, and so on (Sciberras et al, 2015;Vicenzutti et al, 2015;Paul et al, 2017). Among them, shore-to-ship power technology can basically eliminate the emission of pollutants during the berthing period.…”
