After 2005, the International Marine Organization (IMO) has gradually reduced the volume of sulfur oxides that ships are permitted to emit. The sulfur content of ships fuel oil was lowered to 0.5 percent from 3.5 percent under the most recent upper cap, which went into operation at the start of 2020. According to the IMO, the reduction w
