Greenhouse Gas Emissions News

The International Maritime Organization (IMO) has achieved another step towards establishing a legally binding framework to reduce greenhouse gas (GHG) emissions from ships globally, aiming for net-zero emissions by or around, i.e close to 2050. The IMO Net-zero Framework is the first in the world to combine mandatory emissions limits and GHG pricing across an entire industry sector. Approved by the Marine Environment Protection Committee during its 83rd session (MEPC 83) from April 7-11, 2025, the measures include a new fuel standard for ships and a global pricing mechanism for emissions.

DNV Maritime Advisory has confirmed that 11.1 million tons of CO2 emissions were avoided by Jotun coated vessels in 2024.The avoided emissions were verified through a technical evaluation using the DNV MASTERv2 emission prediction model combined with AIS data, and Jotun provided data on average speed loss over a five-year drydocking cycle.“We are happy to showcase the verified effect our efforts within hull performance have for our customers in terms of avoided emissions. This mean that we contribute to the environment with great significance…

Researchers from MIT and Georgia Tech have concluded that burning heavy fuel oil with scrubbers in the open ocean can match or surpass using low-sulfur fuels when a wide variety of environmental factors is considered.The scientists combined data on the production and operation of scrubbers and fuels with emissions measurements taken onboard a bulk carrier owned by Oldendorff Carriers. Gaseous and particulate matter (PM) emissions data were collected while the bulk carrier  was burning 3%S HFO…

The Marine Environment Protection Committee (MEPC) will meet for its 83rd session from April 7 to 11 April, and efforts to reduce GHG emissions from ships will be top on the agenda.Tackling climate change - Reduction of GHG emissions from shipsThe 2023 IMO GHG Strategy outlines a set of “mid-term measures” aimed at reducing greenhouse gas emissions from international shipping. These measures should consist of:• a technical element: a goal-based marine fuel standard designed to gradually lower the GHG intensity of marine fuels…

Australia and Singapore have selected eight projects for funding as part of a A$20 million ($12.6 million) initiative to help reduce emissions in the maritime sector.The Australia-Singapore Initiative on Low Emissions Technologies (ASLET) supports the objectives of the Singapore and Australia Green and Digital Shipping Corridor (GDSC), which will help accelerate decarbonization and digitization of shipping routes between Singapore and Australia. It is jointly delivered by the CSIRO…

The IMO will reconvene in London on March 31 and April 1, for a crucial two-day Intersessional Working Group on Greenhouse Gas (ISWG-GHG 19) meeting. The meeting sets the stage for a decision on a GHG pricing mechanism by the Marine Environment Protection Committee 83 (MEPC 83) on April 7-11 on the future of shipping’s climate responsibility.The 6PAC+ alliance, a group of Pacific, African and Caribbean States, backed by major allies, emphasizes that this meeting is a make-or-break moment for securing a universal GHG levy of $150 per tonne of CO2-equivalent.

The UK Maritime Minister Mike Kane has revealed the government’s new goals for all vessels that operate in UK waters and dock at UK ports to be carbon free.Part of the government’s Plan for Change, the new Maritime decarbonization strategy sets out goals to reduce greenhouse gas emissions by 30% by 2030, 80% by 2040 and to zero by 2050.This will see the UK match the highest level of the ambitious goals agreed at the IMO in its 2023 strategy on reduction of greenhouse gas emission from ships.

The European Commission has adopted a report on the implementation of the EU Emissions Trading System (ETS) for shipping that indicates there is no evidence of major changes in the market that might indicate it is being circumvented.The EU ETS was extended to include maritime transport from January 1, 2024. The report provides an initial analysis of the impacts of this recent policy development that covers around 12,000 large ships.The report’s analysis of shipping traffic data does not show evidence of a general trend in relocation of container transhipment activities…

Uncertainty about the scale and nature of the IMO’s proposed carbon levy is holding back investment in shipping, according to the Christopher J. Wiernicki,  Chairman and CEO of American Bureau of Shipping (ABS).“A carbon levy is a wild card. It will all depend on how it is implemented and enforced. There’s a huge question mark over whether this will deliver for the industry and there is much still to be decided,” said Wiernicki.Wiernicki expressed his concerns during an appearance at CERAWeek energy conference.“Will the levy be set at $18, $100 or even $150 per ton?

Flagship Cruises & Events, a San Diego-based yacht charter, announced a $15.27m grant from the California Air Resources Board (CARB) to develop two fully electric, zero-emission ferries to serve the San Diego to Coronado route. With advanced battery technology, the vessels will not emit any greenhouse gases during operation and will remove the particulate matter associated with traditional combustion engines. The CARB Advanced Technology Demonstration and Pilot Project grant is part of California Climate Investments…

There were no major breakthroughs in the on-going discussions about a universal levy at the IMO's Intersessional Working Group on Reduction of GHG Emissions from Ships (ISWG-GHG 18) last week. Any GHG emissions pricing mechanism is going to mean big change for the industry, and a lot of different sectors within shipping will be impacted.InterManager has pointed out, in a paper submitted to the next meeting of the IMO’s Marine Environment Protection Committee (MEPC83 in April)…

As the global shipping industry wrestles with the challenges of meeting its 2050 decarbonization goal, additive manufacturer Fuelre4m aims to enable ship operators to improve efficiency and reduce emissions now.Fuelre4m’s Re4mx products use nano-biotechnology. When added to any liquid fossil fuel (HFO, LSFO, VLSFO or (up to) B30 Biodiesel fuel), the product reforms the fuel molecules, releasing impurities and changing the structure of complex hydrocarbons.The result is a significant increase in the combustion rate, releasing more power from the fuel and producing fewer harmful emissions.

International efforts to curb GHG emissions from shipping took a step forward as the IMO's Intersessional Working Group on Reduction of GHG Emissions from Ships (ISWG-GHG 18) concluded its latest round of discussions on Friday.The IMO's 2023 GHG Reduction Strategy commits Member States to adopting mid-term measures to reduce GHG emissions from ships in late 2025, including:• a technical element, namely a goal-based marine fuel standard regulating the phased reduction of a marine fuel's GHG intensity; and  • an economic element involving a maritime GHG emissions pricing mechanism.

A rapid transition could lead to premature scrapping of over a third of the global fleet, valued at over $400 billion, unless the vessels undergo costly retrofits to remain competitive, according to a new report from UCL's Energy Institute Shipping and Oceans Research Group.The report assesses the financial risks to the shipping industry from stranded assets due to stricter GHG regulations, due for adoption at IMO this year, in combination with the ongoing global transition to a low-carbon energy system.

The International Chamber of Shipping (ICS) has joined 47 governments in a joint submission to the final round of negotiations at the IMO on a GHG emissions pricing mechanism for international shipping.The joint text is supported by major shipping nations such as Greece, Japan, Korea and the United Kingdom, the world’s largest flag States including Bahamas, Liberia, Marshall Islands and Panama, all EU States (and the European Commission), other African countries such as Nigeria and Kenya…

NYK has signed a deal with ENEOS that will see it purchase marine fuel with CO2 removal credits created through direct air capture with carbon storage.ENEOS will procure the credits from 1PointFive’s STRATOS Direct Air Capture plant in Texas which is scheduled to commence operations in 2025. The credits are generated by removing CO2 from the atmosphere and storing it underground.ENEOS will then sell these credits, along with the marine fuel it supplies, to NYK for five years starting in 2028.ENEOS launched its carbon offset fuel in January 2024.

This week at MarineLink…Two reports released this week, one on the upscaling of green hydrogen production, the other on upscaling CCUS, both point to a lack of government initiatives as hindering investment. Without the establishment of regulations and multi-lateral frameworks, big projects are floundering.DNV’s latest Maritime Forecast to 2050 estimates that shipping’s demand for carbon-neutral fuels will be between 9 and 55 Mtoe in 2030 while the global cross-sector production volume of carbon-neutral fuel will be between 44 and 62 Mtoe.Clearly…
