The Scottish Government has not made any estimates or assumptions around the level of fuel consumption by MV Glen Sannox as this is a matter for CalMac Ferries Ltd (CFL) as the operator.

CFL have confirmed, however, that total marine diesel consumption is estimated to reach around 1,800m3 per year. The vessel is expected to consume around 1,700 metric tonnes of LNG per year. The proportion of annual propulsion by LNG is expected to be around 70%, but this is under constant review.

In 2014, Transport Scotland, supported by Caledonian Maritime Assets Ltd and CalMac Ferries Ltd (CFL), set out the case to procure two new dual-fuel vessels for the Clyde and Hebrides ferry network which included analysis of fuel emissions and estimated operating costs. In November 2023, Transport Scotland requested a report from CFL on expected carbon emissions relating to Liquified Natural Gas, including end-to-end transportation. CFL completed a detailed assessment and provided their findings to Transport Scotland in a report in January 2024. This report has been released and is available on the Scottish Government website via the following link:

CFL have set out a range of activities and actions around fuel use and emissions monitoring in their 2024 – 2027 Environmental Plan and we will continue to work with them to reduce carbon emissions and improve environmental sustainability of ferry operations in the coming years.

MV Glen Sannox has consumed 683m3 of marine diesel and 369 metric tonnes of LNG (Liquified Natural Gas) since she entered service. This has involved sixteen separate LNG deliveries by road tankers.

All Scottish Government grants are managed in line with the terms of the relevant grant offer letter and the Scottish Public Finance Manual.

Under the CHFS (Clyde and Hebrides Ferry Service) contract, the Scottish Government monitors fuel consumption by all vessels operating on the CalMac network. However, there are no plans to publish this data at present.

The Scottish Government does not monitor or publish greenhouse gas emissions produced by, or associated with, vessels operating on the CalMac network. However, CalMac have a reporting requirement under UK MRV (Monitoring, Reporting and Verification) regulations on total carbon emissions for all vessels in their fleet over 5,000 GT (Gross Tonnage).
