'Green' Scottish Ferry Emits Far More CO2 Than Old Diesel Ship

A new Scottish ferry, MV Glen Sannox, intended to be environmentally friendly, will produce significantly more CO2 emissions than the vessel it replaces. CalMac's analysis reveals Glen Sannox's annual CO2 equivalent emissions will be 10,391 tonnes, exceeding the older ship's 7,732 tonnes. The larger size and LNG fuel contribute to Glen Sannox's higher emissions. Including the upstream carbon cost of LNG import might make diesel a better option, according to an expert. The ferry's LNG technology added significant complexity and delays to its construction. The project faced years of delays and cost overruns. The ship's size also necessitates harbor redevelopment before full operation. The ferry's 'green' credentials are questioned due to unexpectedly high emissions. The project highlights the overselling of green technology benefits.
