Tianle Yuan, Associate Research Scientist (613/UMBC), and his team conducted research that resulted in the creation of the first global map of cargo ship pollution. They analyzed the ship-track data (2003-2020) and the effects of sulfur regulations in Emission Control Area (ECA) regions versus non-ECA regions, and the team emphasized that "The evolving impact of the regime changing 2020 fuel standard warrants close monitoring in the coming years given its potential radiative forcing." The research, discoveries, and methods were recently published in Science Advances (Chenxi Wang, Associate Research Scientist (613/UMBC), is one of the co-authors of this paper), and were presented in a UMBC News feature. The team's discoveries were also the focus of an article in WIRED.
