Sustainability In The Shipbuilding Industry Statistics

With EU ETS now covering intra EU voyages and extra trips between EU ports from 1 January 2024 and projected 2024 coverage of about 100 million tonnes CO2e annually, this page pinpoints how regulation is forcing measurable cuts while alternative fuels and efficiency tech compete on cost and carbon. It connects orderbook signals like ammonia at 36% of the zero emission pipeline and methanol at 7% of newbuild orders to the nitty gritty of MRV, sulfur rules, and life cycle trade offs such as methane slip and steel upstream impacts.

EU ETS already expects shipping coverage of about 100 million tonnes of CO2e per year, and the compliance picture is getting sharper through MRV and tighter product and equipment rules. Meanwhile the orderbook is shifting toward zero and alternative fuels, but the scale of efficiency gains from hull, propulsion, and waste heat measures may be what really determines near term emissions. Put those datasets side by side and you start to see a tension between where investment is going and what the lifecycle and operating reality can deliver.

Emissions Baselines Interpretation

For the Emissions Baselines, the starting point is that shipping emissions are substantial and measurable at roughly 100 million tonnes of CO2e annually under EU ETS coverage, while life cycle studies show steel production overwhelmingly drives embodied GHG impacts with typical ship steel at about 1.8 to 2.3 tCO2e per tonne, meaning improvements later in operations only partly change the overall baseline compared with the upstream emissions profile.

Cost Analysis Interpretation

Across the cost analysis evidence, decarbonizing shipbuilding is increasingly shaped by a few repeatable price drivers, with estimates pointing to battery pack costs around $120 to $150 per kWh, scrubber retrofits of roughly $2 million to $8 million per vessel, and propulsion or efficiency upgrades adding about 1% to 15% to upfront costs while measures like air lubrication and onboard energy management can still shorten payback to about 1 to 5 years depending on conditions.
