S5W-12760: John Finnie (Highlands and Islands)

Scottish Green Party

Date lodged: 15 November 2017

To ask the Scottish Government what assessment it has made of the carbon dioxide emissions from its fleet of marine protection vessels.

Answered by: Roseanna Cunningham 21 November 2017

CO2 emissions directly correspond to the actual fuel consumption of the fleet.

When the fleet was last renewed, the best possible engines for fuel efficiency on the market at that time were bought with investment in diesel electric plant, which was at a higher cost than conventional propulsion systems. This ensured the most efficient vessels possible. Fisheries Protection Vessel "Norna", built in 1988, used 6 tonnes of fuel per day. The current Marine Protection Vessels "Jura" and "Hirta" use 2 tonnes of fuel per day for the same mileage covered.

Since then, further fuel efficiencies have been derived from greater reduction in electrical consumption on the vessels whether it be through slower steaming speeds; and better targeting of assets.

Marine Scotland Compliance maintains fuel consumption records but will only be required to have CO2 emissions logged from March 2018.
