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)
EU rules and cleaner fuels are accelerating, while efficiency gains and technologies can cut energy use and emissions.
