© 2015 Taylor & Francis Group, London.The ship building sector is known as one of the oldest manufacturing methods. Both merchant and military ships have always had a great importance down the ages. Today, despite of the existence of different technologies for transportation and defense, ships have still an indispensable role throughout the world. Because of their great carrying capacity, ships’ preferability increased continuously. Besides ships’ effects on worldwide trade and economy, they have an important impact on human health and environment. Ships’ emissions to air, water and land has increased dramatically throughout the last decades and it has been estimated that the amount of the emission will increase depending upon the demand for bigger ships and thus, powerful engines. In this study, ships’ emissions and their impacts on human health and environment is investigated in detail. Based on the real-time fuel consumption data, annual emissions are calculated for three bulk carriers. Then, an emission estimation approach is developed related to a main parameter (Block Coefficient-CB). By using regression analysis, some equations are obtained in order to estimate the emission during the pre-design stage of a ship.
