From January 1, 2020, new limits on sulfur content if fuel adopted in 2016 under the International Convention for the Prevention of Pollution from Ships (MARPOL) will take effect. The new cap will be 0.5 percent, down from the current 3.5 percent.
Most marine fuels currently have a sulfur content of 2.7 percent, according to VASEP.
The rules will affect ships owned by 170 countries that have adopted MARPOL, including Vietnam and the U.S.
From 2020 Contracting States of MARPOL will begin to monitor ships and can detain any found to violate emissions rules.
MARPOL is an international convention covering the prevention of pollution of the marine environment by ships, developed through the International Maritime Organization, a United Nations agency that deals with maritime safety and security.
