    Shipping emissions can cause atmospheric pollution and health issues to residents in port areas. Shipping emission control features have been attempted and implemented throughout the world to mitigate air pollution. In this study, the shipping emissions status in the Port of Yangon and its navigation channels is calculated since it is the largest port and the major hub for ocean-going vessels in Myanmar. The vessel emission estimation model is based on the resistance and power prediction model, and emission volumes of 8 emission pollutants are calculated by classifying the vessel activity phases into voyage, hoteling, and anchorage phases. Then spatial analysis of shipping emission is done to identify the area impacted by high emissions. The highest shipping emissions are found at the Outer Bar area of the Yangon Port, where vessels enter and depart the port as well as may anchor to wait for the tide. To reduce the high emission concentration at the Outer Bar area of the Yangon Port, vessel scheduling should be considered. As the next step, the Port of Yangon should consider establishing an air quality monitoring and measuring system. As a result, emissions can be measured in real time, and such data can be shared with ship operators, terminal operators, and local maritime authorities to improve sustainability efforts such as the air quality documentation system, sustainability reporting and regulatory control. We believe that our study would provide more insights into future research for the Port of Yangon.
