RESIZED IMO Building

The International Maritime Organization (IMO) on Friday (7 July) said it adopted a revised strategy to reduce greenhouse gas emissions from international shipping.

Member States of the International Maritime Organization (IMO), meeting at the Marine Environment Protection Committee (MEPC 80), have adopted the 2023 IMO Strategy on Reduction of GHG Emissions from Ships, with enhanced targets to tackle harmful emissions.

The revised IMO GHG Strategy includes an enhanced common ambition to reach net-zero GHG emissions from international shipping close to 2050, a commitment to ensure an uptake of alternative zero and near-zero GHG fuels by 2030, as well as indicative check-points for 2030 and 2040.

IMO Secretary-General Kitack Lim, said: “The adoption of the 2023 IMO Greenhouse Gas Strategy is a monumental development for IMO and opens a new chapter towards maritime decarbonization. At the same time, it is not the end goal, it is in many ways a starting point for the work that needs to intensify even more over the years and decades ahead of us. However, with the Revised Strategy that you have now agreed on, we have a clear direction, a common vision, and ambitious targets to guide us to deliver what the world expects from us.”

“Above all, it is particularly meaningful, to have unanimous support from all Member States. In this regard, I believe that we have to pay more attention to support developing countries, in particular SIDS and LDCs, so that no one is left behind.”

IMO is the United Nations specialized agency with responsibility for developing global standards for shipping and supporting countries to implement those rules. 

Elements of the Strategy are outlined below:

2023 IMO Strategy on Reduction of GHG Emissions from Ships

The 2023 IMO Strategy on Reduction of GHG Emissions from Ships (the 2023 IMO GHG Strategy) represents the continuation of work by IMO as the appropriate international body to address greenhouse gas (GHG) emissions from international shipping.

Vision

IMO remains committed to reducing GHG emissions from international shipping and, as a matter of urgency, aims to phase them out as soon as possible, while promoting, in the context of this Strategy, a just and equitable transition.  

Levels of ambition

Levels of ambition directing the 2023 IMO GHG Strategy are as follows:   

  • carbon intensity of the ship to decline through further improvement of the energy efficiency for new ships 

to review with the aim of strengthening the energy efficiency design requirements for ships; 

  • carbon intensity of international shipping to decline 

to reduce CO2 emissions per transport work, as an average across international shipping, by at least 40% by 2030, compared to 2008;  

  • uptake of zero or near-zero GHG emission technologies, fuels and/or energy sources to increase 

uptake of zero or near-zero GHG emission technologies, fuels and/or energy sources to represent at least 5%, striving for 10%, of the energy used by international shipping by 2030; and 

  • GHG emissions from international shipping to reach net zero 

to peak GHG emissions from international shipping as soon as possible and to reach net-zero GHG emissions by or around, i.e. close to 2050, taking into account different national circumstances, whilst pursuing efforts towards phasing them out as called for in the Vision consistent with the long-term temperature goal set out in Article 2 of the Paris Agreement.

Indicative checkpoints

Indicative checkpoints to reach net-zero GHG emissions from international shipping:

  1. to reduce the total annual GHG emissions from international shipping by at least 20%, striving for 30%, by 2030, compared to 2008; and 
  2. to reduce the total annual GHG emissions from international shipping by at least 70%, striving for 80%, by 2040, compared to 2008.

Basket of candidate mid-term GHG reduction measures

The 2023 GHG Strategy states that a basket of candidate measure(s), delivering on the reduction targets, should be developed and finalized comprised of both: 

  1. a technical element, namely a goal-based marine fuel standard regulating the phased reduction of the marine fuel’s GHG intensity; and
  2. an economic element, on the basis of a maritime GHG emissions pricing mechanism.

The candidate economic elements will be assessed observing specific criteria to be considered in the comprehensive impact assessment, with a view to facilitating the finalization of the basket of measures.

The mid-term GHG reduction measures should effectively promote the energy transition of shipping and provide the world fleet a needed incentive while contributing to a level playing field and a just and equitable transition.

Impacts on States

The strategy says that the impacts on States of a measure/combination of measures should be assessed and taken into account as appropriate before adoption of the measure in accordance with the Revised procedure for assessing impacts on States of candidate measures. Particular attention should be paid to the needs of developing countries, especially SIDS and LDCs.

Barriers and supportive actions; capacity-building and technical cooperation; R&D

In the Strategy, the Committee recognizes that developing countries, in particular LDCs and SIDS, have special needs with regard to capacity-building and technical cooperation. An appendix provides an overview of relevant IMO initiatives supporting the reduction of GHG emissions from ships (read more on these initiatives).

Next steps

The 2023 Strategy sets out a timeline towards adoption of the basket of measures and adoption of the updated 2028 IMO GHG Strategy on reduction of GHG emissions from ships:

  • MEPC 81 (Spring 2024) – Interim report on Comprehensive impact assessment of the basket of
  • candidate mid-term measures/Finalization of basket of measures
  • MEPC 82 (Autumn 2024) – Finalized report on Comprehensive impact assessment of the basket of candidate mid-term measures
  • MEPC 83 (Summer 2025) – Review of the short-term measure to be completed by 1 January 2026
  • MEPC 84 (Spring 2026) – Approval of measures / Review of the short-term measure (EEXI and CII) to be completed by 1 January 2026
  • Extraordinary one or two-day MEPC (six months after MEPC 83 in Autumn 2025) – Adoption of measures

Target dates:

  • MEPC 85 (Autumn 2026)
  • 16 months after adoption of measures (2027) – Entry into force of measures
  • MEPC 86 (Summer 2027) – Initiate the review of the 2023 IMO GHG Strategy
  • MEPC 87 (Spring 2028)
  • MEPC 88 (Autumn 2028) – Finalization of the review of the 2023 IMO GHG Strategy with a view to adoption of the 2028 IMO Strategy on reduction of GHG emissions from ships

Life cycle GHG assessment guidelines adopte

The MEPC adopted Guidelines on life cycle GHG intensity of marine fuels (LCA guidelines) for consideration and adoption. The LCA guidelines allow for a Well-to-Wake calculation, including Well-to-Tank and Tank-to-Wake emission factors, of total GHG emissions related to the production and use of marine fuels.

Interim guidance on the use of biofuels

The MEPC approved an MEPC circular on Interim guidance on the use of biofuels under regulations 26, 27 and 28 of MARPOL Annex VI (DCS and CII).

Marine Environment Protection Committee (MEPC 80)

The Marine Environment Protection Committee (MEPC) addresses environmental issues under IMO’s remit. This includes the control and prevention of ship-source pollution covered by the MARPOL treaty, including oil, chemicals carried in bulk, sewage, garbage and emissions from ships, including air pollutants and greenhouse gas emissions. Other matters covered include ballast water management, anti-fouling systems, ship recycling, pollution preparedness and response, and identification of special areas and particularly sensitive sea areas.

MEPC 80 met 3-7 July 2023 at IMO Headquarters in London. It was attended by some 1,800 delegates (in person and remotely).

Wallenius Wilhelmsen, EUKOR secure green methanol bunker fuel supply from EcoMethanol

South Korean firm EcoMethanol on Wednesday (26 August) signed a memorandum of understanding (MoU) on the supply of green methanol with Taebaek City, Hyundai Corporation, Wallenius Wilhelmsen Ocean AS of Norway and EUKOR Car Carriers. 

The signing took place at EUKOR’s head office in Seoul.

EcoMethanol is the special purpose company set up by South Korean clean energy firm Plagen to build a green methanol plant in Taebaek, Gangwon State. 

Under the MoU, Hyundai Corporation will buy the methanol produced in Taebaek and sell it on to the two carriers, which will burn it as fuel in their own fleets. Taebaek City takes part as an equity co-investor and will provide administrative and policy support. Production, trading and end use are tied together in a single chain, the first such arrangement in Korea.

Manifold Times previously reported Taebaek City and Plagen signing an investment agreement for a new green methanol production plant in the South Korean city that will be supplied as bunker fuel.

The plant will produce 15,000 metric tonnes (mt) a year from forestry residues, using dual fluidized bed (DFB) gasification, a process already proven in commercial operation. Total investment is KRW 120 billion.

EcoMethanol holds Korea’s integrated environmental permit, has secured its site in the Dongjeom Industrial Complex and has completed basic design. Construction is due to start in December 2026 and commercial production in January 2029. The plant will employ 36 people locally.

Taebaek’s role as a production hub is written into both national and provincial plans. The Taebaek Jangseong Colliery Economic Revitalization Project cleared preliminary feasibility review in 2025 with a green methanol facility included in its scope, and Gangwon State lists a green methanol cluster in its mid- to long-term investment plan for former coal-mining regions. Dongjeom will be the first of these facilities to be built, because its industrial site is already developed.

Carbon regulation in shipping is no longer a prospect. The EU Emissions Trading System now covers maritime transport, the FuelEU Maritime regulation on greenhouse gas intensity is in force, and the International Maritime Organization is moving toward adoption of its Net-Zero Framework.

Korean carriers are already buying green methanol. HMM’s methanol-fueled container ships HMM Green and HMM Forest took on 2,900 mt and 3,110 mt at Yangshan Port in Shanghai in March and May 2025. 

The car carrier Arctic Tern, operated by EUKOR, loaded about 2,800 mt in Shanghai in July 2026 before starting commercial service on the Asia-Europe route. All of that fuel was made in China.

Korea produces none of its own. Ulsan Port was the first port anywhere to bunker green methanol for a ship, in 2023, but the fuel had been imported. 

Korea consumes roughly 2 million mt of methanol a year, most of it imported and made from fossil feedstock.

The Taebaek plant would be the country’s first domestic source of clean marine fuel.

DNV report: Regulatory uncertainty demands fleet strategies built for multiple futures

Regulatory uncertainty is increasing pressure on shipowners to make investment decisions that remain viable across multiple future scenarios, said classification society DNV on Thursday (27 August). 

According to DNV’s 10th Maritime Forecast to 2050, stronger global regulatory signals could accelerate the uptake of energy-efficiency measures, enabling the global fleet to consume up to 25% less energy by 2050 compared to a scenario where regulation is driven by regions.

The report examines four regulatory scenarios, ranging from adoption of the IMO Net-Zero Framework (NZF) in its current form to its outright rejection, which could lead to a period of prolonged regulatory gridlock, and explores the implications of these outcomes for fuel demand, energy efficiency uptake, and long-term fleet fuel and technology strategies.

Cristina Saenz de Santa Maria, CEO Maritime, DNV, said: “Ships ordered today will operate well beyond 2050, but many of the factors shaping their future performance remain uncertain. Regulatory requirements are advancing faster than the fuel, infrastructure, and technological systems needed to support them, making long-term investment decisions increasingly complex. The industry therefore needs greater clarity and alignment among all stakeholders to provide the confidence required for long-term investment. In the meantime, shipowners need strategies that deliver benefits today while remaining resilient across a range of regulatory and market outcomes.”

Energy efficiency is one of the most immediate and practical levers available to shipowners, delivering value across regulatory outcomes whether implemented at the newbuild stage or as a retrofit. A case study of a hydrodynamic measures retrofit on a 5,000 TEU container vessel showed potential annual fuel savings of 16%, with a payback time of around one to four years depending on future fuel prices. Retrofits can add similar value across many ship types and with sufficient planning can typically be completed during a standard class-renewal dry docking.

The development of the marine low-GHG fuel market remains a key challenge. While significant progress has been made in expanding alternative-fuel capabilities of vessels, scaling fuel production depends on confidence that demand will materialize. DNV projects shipping demand for low-GHG fuels to range from 4 to 22 Mtoe by 2030 and 33 to 185 Mtoe by 2050, depending on regulatory outcomes, with uptake also shaped by future uptake of shore power, plug-in hybridization, nuclear power, and onboard carbon capture systems.

Current project pipelines indicate a maximum global supply of 270 Mtoe by 2030, although actual volumes are likely to be lower due to project delays and other uncertainties, and shipping will need to compete with other industries for its share. However, the cost of reducing emissions varies significantly between fuel pathways, with abatement costs ranging from about 180 to 1,290 USD per tonne of CO₂ avoided, highlighting the importance of regulation and market incentives in enabling low-GHG fuel markets to develop.

Øyvind Sekkesæter, lead author of Maritime Forecast to 2050, said: “Scenarios explored in this year’s report show how different regulatory futures can lead to very different outcomes in energy efficiency uptake, fuel demand, and consequently, GHG emissions. By testing fuel and technology choices across multiple scenarios, shipowners can identify strategies that create value today while preserving flexibility as regulation, fuel availability, prices, and technologies evolve. Strategies that each owner chooses will also be dependent on their fleet type and operating context.”

Key findings from the report: 

  • Several regulatory futures remain possible as the IMO continues negotiations on the Net-Zero Framework, with these outcomes shaping investment decisions, low-GHG fuel uptake, and energy-efficiency deployment across the global fleet.
  • With global regulatory incentives in place, the world-fleet could consume 25% less energy by 2050 than under a scenario limited to regional regulations.
  • Energy efficiency can pay off regardless of regulatory outcome – 5,000 TEU container ship case study shows 16% annual fuel savings from hydrodynamic measures retrofit.
  • Shipping demand for low-GHG fuels could range from 4 to 22 Mtoe by 2030, and 33 to 185 Mtoe by 2050, depending on regulatory outcomes and the availability of these fuels in a competitive global market.
  • Current project pipelines indicate that a maximum of 270 Mtoe of supply could be available by 2030, though actual volumes are likely to be lower due to project delays and other uncertainties, and shipping will need to compete with other industries for its share.
  • Testing fuel and technology strategies across different scenarios can help shipowners identify robust choices for an uncertain transition. Testing, piloting, and verifying technologies can provide the trusted performance data needed to make investment decisions with greater confidence.

The Australian Government on Wednesday (26 August) released the Maritime Emissions Reduction National Action Plan (MERNAP), outlining practical actions government and industry can take to continue decarbonisation of the maritime sector.

One of the actions highlighted in the plan include that the Australian Government will further promote and support the use of low carbon fuels in shipping to reduce the carbon footprint of transporting Australia’s green energy exports and the acceleration of the low carbon liquid fuels (LCLF) industry under programmes such as the Future Made in Australia Innovation Fund.

Through a stocktake of programmes, the Department of Infrastructure, Transport, Regional Development, Communications, Sports and the Arts, will flag the requirements of the maritime industry with relevant programmes. 

“This work will feed into the development of a bunkering strategy to help guide investment in green fuels,” it said. 

Announced in Budget 2026-27, the Australian Government is investing $4 million to develop a green fuel bunkering strategy, to prepare Australian ports to diversify the maritime fuel mix, supported by targeted industry trials and studies. It will help secure long-term resilience for the industry that carries more than 99% of Australia’s trade by volume.

The Government will also encourage and support investment in storage and bunkering facilities for low carbon fuels, shore power infrastructure and expansion of port energy capabilities.

The actions in the MERNAP have been deliberately developed to take account of the significant Australian Government investments in maritime and energy decarbonisation initiatives, including $4 million to develop a green fuel bunkering strategy. 

Stretching across ports, shipping, energy, domestic commercial vessels and skills and training, the MERNAP identifies key priority actions to support decarbonisation while recognising Australian shipping must remain competitive and prosperous in the international market

The MERNAP complements existing Australian Government incentives and policies including the $1.1 billion Cleaner Fuels Programme, the Green Fuel Bunkering Strategy, the $30 million Australia-Singapore Low-Emissions Technologies Initiative for Maritime and Port Operations, the $55 million Transport Resilience And Capacity Kickstart programme and the $13.8 million Maritime Skills and Training Initiative.

It also complements the country’s $100 million investment in a new Clean Energy Precinct at the Port of Newcastle, which is expected to facilitate production, storage, distribution and export of clean-energy products including hydrogen and ammonia.

Australia’s Minister for Infrastructure, Transport, Regional Development and Local Government Catherine King, said: “The recent conflict in the Middle East has demonstrated to us how critical it is to build resilience and sustainability within our maritime industry.

“In a nation where our maritime sector is responsible for 99 per cent of our international trade, the MERNAP is a vital piece of our journey toward a sustainable future.

“It also presents an unparalleled opportunity to be a low and zero-carbon energy exporter of choice internationally, while creating new jobs and industry within the sustainable maritime sector locally.”
