The contract with the European Maritime Safety Agency (EMSA) has been developed in response to new limits on the sulphur content of marine fuels that came into force in January 2015, as well as rules that the sulphur oxide (SOx) content of marine fuels must be monitored and reported by member states of the EU.
LNG-fuelled ships have reduced emissions (nitrogen oxide, sulphur oxide and particulate matter) as compared with heavy bunker oil and even low-sulphur marine diesel.
The report said Welsh emissions were "much higher" than the UK average for nitrogen oxides, sulphur oxide and, most notably, for lead and carbon monoxide.
Annex VI of the Marpol Convention (in force since 19 May 2005) regulates emissions from ships of nitrogen oxide (NOx), sulphur oxide (SOx), volatile organic compounds (VOCs), polychlorinated biphenyls (PCBs), heavy metals and chlorofluorocarbons (CFCs).

There has been about 60% decrease in SOx (sulphur oxide) emissions from RasGas operations and 54% in total acid/sour gas flaring compared to 2010, the report said, highlighting the 66% decrease in total VOC (volatile organic compounds) emissions compared to 2010.
In addition, nitrogen oxide and sulphur oxide emissions will also be reduced (up to 40% less nitrogen oxides and 10ppm sulphur oxides compared with 600ppm of conventional Jet-Al-fuel) due to the very low nitrogen and sulphur content of the biofuel compared to fossil fuel.
