OTHER SIGNIFICANT AIR EMSISIONS
SULPHUR & NITROUS OXIDES
Combustion of fossil fuels onboard vessels produces Sulphur
SOx emissions are mainly due to the presence of sulphur
Oxides (SOx) and Nitrogen Oxides (NOx), which are not

maximum of 0.1% sulphur limit. Consequently, SOx emission
has decreased dramatically.
The level of NOx emissions from a vessel depends on the
engine design, operating pro昀椀le, and quality of fuels. However,
Since 2019, Gearbulk has reduced the SOx emission by 81%
whereas modern engines generally generate less NOx, older
(from 14,602 to 2,788 tonnes) and our NOx by 15% (from
