Sustainability In The Shipbuilding Industry Statistics 2026

Sustainability in shipbuilding spans two linked goals: cutting emissions from voyages and reducing the greenhouse impact of the materials and systems ships carry. This page connects the policy and reporting layer—like EU MRV, EU ETS, and SECA sulphur rules—with the technical levers that lower fuel use and lifecycle GHG, from hull and propulsion efficiency to alternative fuels. It also examines upstream drivers such as steel production and how compliance needs shape shipyard decisions.

Key Takeaways

EU ETS covered intra-EU maritime emissions and extra-EU trips between EU ports, with an estimated 2024 ETS coverage of about 100 million tonnes CO2e annually for shipping (reported expectation)
25% of global shipping sector emissions could be reduced by energy-efficiency improvements by 2030 in IEA’s 2022 scenario for technical measures (share stated in IEA analysis)
7% of shipyard emissions are typically associated with steelmaking upstream (scope depends on LCA boundary) in industry LCA summaries (reported contribution by scope in published LCA synthesis)
Ammonia-fueled vessel orders were 36% of zero-emission orderbook by number by end-2023 (from DNV’s market tracking breakdown)
Methanol-powered vessels represented 7% of newbuild orders in 2023 in major order-tracking datasets (reported share of alternative fuel newbuild pipeline)
Regulation (EU) 2019/1020 extended EU market surveillance requirements relevant to maritime equipment, supporting environmental product compliance frameworks (regulatory scope)
EU MRV for shipping requires reporting of CO2 emissions and other parameters; targets cover all ships calling at EU ports above the threshold, with reports submitted annually (scope stated by the EU Commission Implementing Regulation)
EU ETS for shipping started on 1 January 2024 for emissions from voyages between EU ports (legal basis: EU ETS directive extension adopted by EU co-legislators)
A typical upside of around 10% lower energy use has been reported for designs that improve hull form and propulsive efficiency (range varies by ship type) in ship efficiency retrofit evaluations by IEA
IMO’s EEDI/EEXI framework is designed to reduce energy consumption per transport work by requiring incremental efficiency improvements for new ships (quantitative reduction factors depend on ship type and size)
A 2020 peer-reviewed study found up to 15% fuel savings from propeller upgrades (efficiency improvement), quantified in model and sea-trial contexts across vessel cases
A 2022 IEA report projected global cumulative investment needs for clean energy transitions; for shipping, it estimated that clean fuels and efficiency measures require tens of billions of dollars annually (order-of-magnitude stated by IEA)
Battery systems represent a major cost driver for battery-electric vessels; a 2023 vendor benchmark reported pack costs around $120–$150 per kWh for large-scale deployments (range depends on application and procurement)
Scrubber retrofits cost typically range between $2 million and $8 million per vessel depending on vessel type and installation scope (reported retrofit cost range in industry analysis)

Europe is tightening emissions rules as efficiency gains and zero emission orders accelerate shipbuilding decarbonization.

EU ETS covered intra-EU maritime emissions and extra-EU trips between EU ports, with an estimated 2024 ETS coverage of about 100 million tonnes CO2e annually for shipping (reported expectation)

25% of global shipping sector emissions could be reduced by energy-efficiency improvements by 2030 in IEA’s 2022 scenario for technical measures (share stated in IEA analysis)

7% of shipyard emissions are typically associated with steelmaking upstream (scope depends on LCA boundary) in industry LCA summaries (reported contribution by scope in published LCA synthesis)

Life-cycle analysis of conventional shipbuilding materials indicates that steel production dominates life-cycle GHG impacts, accounting for a major majority of embodied emissions (reported share range across LCAs)

A 2020 cradle-to-gate study estimated embodied emissions for typical ship steel at around 1.8–2.3 tCO2e per tonne of steel produced (range by production route and electricity mix)

For LNG-fueled ships, methane slip can offset some well-to-wake climate benefits; one review quantified methane slip sensitivity where leakage above about 3% can erase part of the GHG advantage versus oil (review threshold stated)

A 2023 peer-reviewed review found that GHG savings from alternative marine fuels vary widely, with life-cycle reductions ranging from 10% to over 90% depending on production pathway and engine/fuel system assumptions

Interpretation

Emissions Baselines Interpretation

Under the Emissions Baselines view, shipping and shipbuilding emissions are dominated by scale and upstream material factors, with EU ETS covering roughly 100 million plus tonnes in 2024 and studies showing steel production accounts for the bulk of life cycle GHG impacts, including embodied emissions of about 1.8 to 2.3 tCO2e per tonne of steel, while potential operational efficiency gains of up to 25% by 2030 do not address this baseline materially.

Methanol-powered vessels represented 7% of newbuild orders in 2023 in major order-tracking datasets (reported share of alternative fuel newbuild pipeline)

Interpretation

Industry Trends Interpretation

For industry trends in shipbuilding, zero emission momentum is clearly building with ammonia fueled vessels making up 36% of the zero emission orderbook by number by end 2023, while methanol powered ships accounted for 7% of newbuild orders in 2023.

Regulatory & Compliance7 stats

Regulation (EU) 2019/1020 extended EU market surveillance requirements relevant to maritime equipment, supporting environmental product compliance frameworks (regulatory scope)

EU MRV for shipping requires reporting of CO2 emissions and other parameters; targets cover all ships calling at EU ports above the threshold, with reports submitted annually (scope stated by the EU Commission Implementing Regulation)

EU ETS for shipping started on 1 January 2024 for emissions from voyages between EU ports (legal basis: EU ETS directive extension adopted by EU co-legislators)

EU Sulphur limit in SECA areas requires 0.10% m/m sulphur from 1 January 2020 (SECA compliance thresholds referenced in EU policy materials)

In the EU, the shipbuilding sector is subject to the Industrial Emissions Directive (IED) activities in certain cases; permitting coverage depends on capacity thresholds (Directive includes quantified thresholds)

Ship Recycling Regulation requires using the Inventory of Hazardous Materials (IHM) and provides obligations for inspections of ships before recycling (as mandated by EU law)

A 2022 European Commission impact assessment estimated that reducing plastic in maritime operations has compliance effects measured in millions of EUR due to waste management and reporting (quantified within IA tables)

Interpretation

Regulatory & Compliance Interpretation

Regulatory and compliance pressure in EU shipbuilding is tightening quickly, with major frameworks such as EU MRV and the EU ETS both moving into full reporting or trading force, while the SECA sulphur cap drops to 0.10% m/m from 1 January 2020 and ship recycling rules introduce mandatory IHM-based oversight.
