Mobile source port emissions are generated by marine vessels and by land-based sources at ports. Marine emissions come primarily from diesel engines operating on ocean-going vessels (OGVs), tugs and tows, dredges, and other vessels operating within a port area. Land-based emission sources include cargo handling equipment (CHE) such as terminal tractors, cranes, container handlers, and forklifts, as well as heavy duty trucks and locomotives operating within a port area. These land-based sources also are likely to have diesel engines.;The purpose of this study was to synthesize various literature relating to port emissions. There are various hotspots which feature a big number of sources of pollutants all at the same time. For example, the port of Houston handles about 70 percent of the containerized cargo in US Gulf of Mexico. There are 8 main terminals, six of which are general cargo and two are container terminals named Barbours cut and Bayport.;Emission factors analyzed in this study are Carbon Dioxide (CO2 ), Oxides of Nitrogen (NOx), Hydrocarbons (HC) and particulate matter (PM). This paper also analyses these emissions from various sources including heavy-duty trucks, cargo handling, harbor craft, ocean-going and freight trains. Other sources included as contributors to the emissions include Tenants. Included also in the discussion are some of the regulation strategies that have been put in place; both presently and in the future to avert the issues pertaining Port emissions.;This paper follows the format of a report with the main sections including introduction, analysis of literature, methodology, analysis of the results and making relevant recommendations that will aid in mitigating the emissions. Notably, these major topics cover various subtopics to assist in a detailed synthesis of the study.
