The report, Shipping Emissions in Ports, says that most of CO2 emissions in ports from shipping are in Asia and Europe (58 percent), but this share is low compared to their share of port calls (70 percent). European ports have much less emissions of SOx (5 percent) and PM (7 percent) than their share of port calls (22 percent), which can be explained by the EU regulation to use low sulfur fuels at berth.

The ports with the largest absolute emission levels due to shipping are Singapore, Hong Kong (China), Tianjin (China) and Port Klang (Malaysia). The distribution of shipping emissions in ports is skewed: the ten ports with largest emissions represent 19 percent of total CO2 emissions in ports and 22 percent of SOx emissions.

The port with the lowest relative CO2 emissions (emissions per ship call) is Kitakyushu (Japan); the port of Kyllini (Greece) has the lowest SOx emissions. Other ports with low relative emissions come from Japan, Greece, UK, U.S. and Sweden.
