(Reuters) - Shipping fuel regulations introduced in 2020 have led to a substantial cut in sulphur dioxide (SO2) pollution, but may also have made the ocean warmer by reducing cloud cover, according to a modelling study in a paper published late on Thursday.
International Maritime Organization (IMO) rules to tackle marine pollution forced shippers to cut their fuel sulphur content to 0.5% from 3.5%, leading to an 80% decline in SO2 emissions, according to a research team led by Tianle Yuan at the University of Maryland.
