Alternative fuels, inexperienced metal and renewable power are basic to greenhouse gasoline (GHG) emissions discount through the life cycle of a vessel, an industry-first cradle-to-grave examine on a newbuild LNG service has revealed.
Carried out by Lloyd’s Register, Knutsen, HD Korea Shipbuilding and Offshore Engineering (HD KSOE), and HD Hyundai Heavy Industries (HHI), the evaluation has highlighted the environmental output at every stage of a vessel’s life.
Namely, the six-month examine, which started in June 2023, has measured the carbon emissions generated all through the whole life cycle of a 174,000 m3 newbuild LNG Carrier, from cradle (uncooked materials extraction) to gate (shipbuilding), gate to end-of-life (operation), and end-of-life and to grave (demolition, recycling, and waste disposal).
Research carried out as a part of the joint growth mission (JDP) reveals the vast majority of emissions are created through the operational interval of a vessel’s life cycle, however that these might be lowered by roughly 90% via using zero- or low-carbon fuels.
Of the general operations determine, 79% of GHG emissions are generated via ship operations (tank-to-wake), with 21% attributed to mining and transport (well-to-tank) of the fuels, highlighting the numerous constructive impression of low- or zero-carbon fuels on emissions discount.
The examine additionally reveals that GHG emissions through the shipbuilding stage (gate) might be considerably lowered if inexperienced metal – metal with low or zero GHG emissions embodied on the manufacturing stage – is launched into the method. The use of renewable power may additionally result in a GHG emissions discount of round 60% on the yard degree.
The evaluation additionally takes under consideration all emissions related to the vessel all through its life cycle.
“The IMO regulations are progressively evolving to encompass the entire value chain and Scope 3 emissions disclosures are gaining traction.
“The methodology created and tested as part of the study will provide a baseline for all life stages of a new construction vessel and serve as a benchmark for comparing the life cycle emissions of other LNG carriers.
“LR is seeing strong demand for LCA assessment, with leading shipowners keen to identify the most impactful measures to reduce their environmental footprint, and charterers looking to minimise their Scope 3 emissions,” mentioned Andy McKeran, LR Chief Commercial Officer.
“In preparation for the forthcoming EU Corporate Social Responsibility Directive (CSRD), and other similar regulations across the globe, ship owners will be required to produce sustainability reports disclosing their Scope 3 emissions and outline strategies for mitigation. This LCA analysis brings owners one step closer to meeting these requirements,” mentioned Jarle Østenstad, Knutsen Director of Newbuilding and Innovation.
