Prevention of air pollution includes ozone-depleting substances, nitrogen oxides (NOx), sulphur oxides (SOx) and volatile organic compounds (VOC). It also contains restrictions against combustion of ship generated of waste onboard ships in Swedish territorial waters. Annex (VI) in MARPOL regulates emissions from these substances to prevent and reduce the risk of negative environmental impact from shipping. Annex VI in MARPOL has been incorporated in TSFS 2010:96.
TSFS 2010:96 also addresses sulphur control areas in which the maximum sulphur content in ship’s fuel is allowed to be 1.50 percent by mass. Further information can be found under "Sulphur content in bunker oil".
