In 2008, the International Maritime Organization (IMO) adopted amendments to the MARPOL Annex VI regulations, setting stricter fuel requirements for the coming years. Since 1st of January 2012, the SOX concentration limit for marine fuels is 3.5 %. From 2020 onwards, this limit will even be lowered to 0.5 %.

In addition, the IMO has also established Emission Control Areas (ECAs), e.g. the North and Baltic Sea, in which a more stringent SOX limit of 1.0 % has to be observed already today. From 2015 onwards, this limit will be further reduced to 0.1 %. Moreover, a NOX emission limit of 3.4 g/kWh will apply within some ECAs starting in 2016 (global limit: 14.4 g/kWh).

As LNG has the best environmental record of all ship fuels in use, it does not only allow ship owners and operators to meet the new IMO standards, but also ensures that they can fulfil even stricter requirements in the future.
