Ports are a major source of economic activity and environmental pollution. They use a variety of
equipment for loading/unloading and movement of cargo, such as marine vessels, cranes, trucks
and railroads. These activities can cause large amounts of pollution to the air, water and soil me-
dia. Despite the pollution generated, it also serves as a medium for tourism with its cruise liners.
This paper discusses port activities and how it effects the environment. The main focus of this pa-
per is Knowledge Sharing for Sustainability of Ports. Sustainability indicators should help in eva-
luating port conditions and this knowledge sharing among the proposed 10 major world ports
should accelerate economic growth and use of latest technologies for pollution reduction.

1. Introduction
A harbor area such as coastal areas, great lakes and inland river systems where ships load and unload are consi-
dered as a port. Ports provide shore side facilities for the transfer of cargo between ships, barges, railroads and
trucks. They also have cruise terminals for passengers.
Ports and Its Economic Importance
In the coastal regions, Ports play a major role for economic growth. Port cities have always been at a higher po-
sition in the aspect of economic life for many centuries. More infrastructure, employment and associated services are
required as the goods and passengers increase with time. This affects the local and regional economy and envi-
ronment in many ways. Ports are a crucial connection between sea and land transportation. Ports also serve as a
social function by providing jobs to people.
Ports provide benefit for international trade. More than 80% of cargoes are transported by sea. They serve as
global entry point and source of growth with low trade costs for host ports. At the same time, there are some disad-
vantages associated with it like reducing the attractiveness of the city due to pollution, traffic and noise (OECD, 2014).
About one third of the total worth of global trade is done by the liner shipping industry which is the most effi-

cient way of goods’ transport (WSC, 2014). “In one year, a single large containership might carry over 200,000
container loads of cargo. It would require hundreds of freight aircraft, many miles of railcars, and fleets of trucks to
carry the goods that can fit on one large liner ship (WSC, 2014).” In the US (2007) port activity contributed more than
$3.15 trillion to the Gross Domestic Product and 13.3 million port related jobs were generated (AAPA, 2014).
Table 1 lists the top 10 container ports of the world (on the basis of the total volume in 2011 and 2012) and
Table 2 lists the top 10 ports of the United States (on the basis of total tons in 2011).
2. Port Activities
The activities and operations carried out at any port depend largely on the type and volume of cargo being
shipped. The operations related activities are the following:
1) Transpor tation
2) Cargo handling
3) Building/grounds maintenance
4) Chemical storage and handling
5) Fueling
6) Ship air emissions
7) Painting and paint stripping
8) Rail maintenance
9) Vehicle and equipment maintenance
10) Ship breaking, repair and maintenance
Cons id er ing the variety of processes carried by ports and the potential to consume a huge amount of energy
and emit large quantities of multi-media pollutants (solid wastes, liquid wastes, and air pollutants), there is a
great need for a knowledge-based system to manage environmental affairs of ports around the world. This is
particularly important as the mismanagement of port activities and related emissions/waste discharges can im-
pact the community in the immediate vicinity (AAPA, 2014).
2.1. Pollution from Port Operations
Enormous engines running on diesel fuel, diesel trucks, trains, cargo handling equipment, cranes and other
equipment at ports cause a tremendous impact on the environment which could affect the health of workers and

local communities (NRDC, 2014). All the activities mentioned above may not be performed at every port; also
each activity will not generate the same amount of pollution at every port. Table 4 gives the pollutant informa-
tion and their pathways for the sub activities mentioned in Table 3 (Dunn et al., 2011).
2.2. Air Pollution
Major air pollutants from diesel engines at ports are particulate matter (PM), volatile organic compounds
(VOCs), nitrogen oxides (NOx), and sulfur oxides (SOx). Percentage emissions of NOx and PM10from various
Port activities are shown in F igure 1. In addition to these pollutants, there are other air pollutants like carbon
monoxide (CO), formaldehyde, heavy metals, dioxins, and pesticides. These pollutants may cause asthma, other
respiratory diseases, lung cancer, cardiovascular disease, and premature death. Therefore, reduction of pollutant
emissions and improvement of air quality in the vicinity of ports is one of the major environmental concerns and
needs to be managed (NRDC, 2014).
2.3. Water Pollution
Dirty water from ships may be directly dumped into the sea or leached into it, which affects the water quality
and causes problems to the human health and to the life of marine species. It causes a decrease in oxygen level,
accumulation of toxins in fish and degrading aquatic life. At the hull of a ship water gets contaminated with oil
called as Bilge. It must be cleaned and emptied regularly to prevent contamination by hazardous vapors. Bilge along
with other wastes from the ship poses a serious threat to aquatic life. Port water used by ships is called Ballast water,
stored in tanks. Ballasting is important for cargo loading and unloading activities and improves stability. To prevent
the growth of marine organisms on ships, antifouling additives are used in paints. These are mixed with paints and
coated on ship surface, which are toxic in nature (NRDC, 2014). AFS Treaty prohibits the use of antifouling agents
like organotins and tributyltin (TBT) given the fact that they are harmful to the marine environment (AAPA, 2014).
There are international and national regulations for vessel discharge which need to be followed accurately to
prevent irreparable environmental damages.
3. Concept of Knowledge Sharing
The University of New Orleans (UNO) is using the Port of New Orleans as a case study to develop/propose a
user friendly intelligent application to promote sustainability at ports. This will be achieved by team work which

includes Civil & Environmental Engineering graduate students, faculty, Computer Science students, and the
personnel of the Port of New Orleans. The results and products of this research and application can be applied to
all ports to improve and manage environmental quality in our surroundings in a better way. Figure 2 depicts the
concept of this research.
4. Methodology of Building a Knowledge-Based (KB) System for Promoting
Sustainability at Ports
Process being used by UNO Researchers to quantify the pollution load from the ports and create a knowledge-
base for promoting sustainability:
Collaborate with the Port of New Orleans to understand the processes in detail.
Benchmark pollution loads (multimedia pollutants (air, water, solid).
Identify sustainability indicators important for the Ports.
Calculate the real time values for the identified indicators for The Port of New Orleans.
Survey ten major ports to understand the indicators for other ports using the online system.
Design and develop knowledge-sharing methodology to improve performance of participating ports.
Different environmental indicators should be considered for ports sustainability such as energy consumption,
water consumption and discharge from vessels, sanitary wastewater from cruise liners and offices, solid and ha-
zardous wastes, air pollution, diesel power, fueling, painting, and welding. Other indicators like employment
potential, secondary economic impacts and tertiary economic impacts will be considered as cost indicators
which have a critical role for managing and quality improvement. The UNO application or knowledge-based
system will use data from participating ports on a 5 - 10 year scale in computing indicators in useful units. For
instance, energy consumption can be calculated as Energy used/100,000 tons of cargo, Energy used/100,000
barrels of crude, or Energy used/1000 ft2 of the building space (office or warehouse). In the same way, other in-
dicators can be calculated and analyzed. In addition, UNO application aims to adopt EPA and international reg-
ulations/ guidelines to evaluate participating Ports and provide rational recommendations that are environmen-
tallysensible, economically-viable, and socially-responsible.
Autho r s believe that the proposed Knowledge-Based (KB) System (Web-Based) can be accessed by the con-
sortium of ports under the leadership of MERIC, which will promote “sustainability” by reducing pollution load,
increasing profitability, and improving social relevance.
5. Conclusion
Every country has its national and international sector of transportation, in which a major role is played by
ocean-going and inland waterways. They are classified as cargo and passenger vessels. As mentioned in this pa-
per, Por ts have potential to produce large amounts of pollution. The amount of pollution can be a function of the
amount of fuel consumed; work done, quantity of materials handled, types of materials handled, design of the
Port and its logistics, Port equipment, and more. Different ports around the world have various technologies,

equipment and logistics for their day-to -day operations and pollution control. The goal of this project is to com-
bine the knowledge available at MERIC-UNO and the World Ports on a single platform, like a web-based ap-
plication (KB System) which will be accessible to users to implement technologies and strategies to reach the
goals of sustainability in an efficient manner. This is achieved by identification of sustainability indicators for
ports and benchmarking them. The study will use and compare these indicators with other major ports in the
world to attain sustainability through knowledge-sharing to promote growth. The KB System to be developed is
aimed to improve Port performance, reduce costs, improve profitability, and protect the public health & the en-
