CALCULATING THE VOLUME OF EMISSIONS FROM VIETNAMESE SHIPPING FLEET

Abstract

Shipping with outstanding advantages in volume and distance is playing an important role in the global economy. With more than 90,000 commercial ships, with a total tonnage of 1.86 billion DWT, transport more than 80% of global commercial cargo. Along with the economic development of the country, the maritime industry is also undergoing strong changes, developing a fleet of shipping ships with 1,276 ships, total tonnage of 8,716 million DWT. Marine activities also emit emissions, causing negative impacts on the global environment and climate-change. The International Maritime Organization (IMO) has made many efforts to develop a legal and technical framework for controlling and reducing emissions from ships such as Annex VI MARPOL, Guidelines for building legal framework. Furthermore, Vietnam has committed to implementing the Paris Agreement (COP24). Therefore, calculating emissions from Vietnamese ships is an urgent requirement. In this article, the calculation method will be analyzed and selected to calculate the emissions from Vietnamese ships. Calculation results show that, in 2019, Vietnam's shipping fleet has emitted 4.03 thousand tons of CO₂, 66.27 tons of NO_X, 34.47 tons of SO_X, 5.29 thousand tons of PM. This result is the foundation for researching and building a national stratergy and a national action plan to control emissions from Vietnam’s shipping fleet.
