The CO2 emissions of a long-delayed and over-budget ‘green’ Scottish ferry will be far larger than that of the 31 year-old diesel ship it is set to replace. BBC News has more.
An emissions analysis by CalMac has calculated MV Glen Sannox will emit 10,391 equivalent tonnes of CO2 a year compared with 7,732 for MV Caledonian Isles.
The dual-fuel ferry has more car capacity but requires larger engines which also emit methane, a greenhouse gas with a far greater global warming effect than CO2.
