With huge expectations on our sector to deliver a new offshore energy mix, safely and ever more sustainably, investment decisions are being made today which will impact on tomorrow's emissions. Now is the right time to bring Members' together to explore some of the solutions that will need to be developed.

Get involved today

Together we will need to find the solutions for a dramatic and transformative shift in approach… We hope you will be able to join us and play your part.

Replay ProjectGHG forum

Replay all the sessions from our forum in April 2023, which took place at Board member Boskalis' campus in Papendrecht, Netherlands.

We brought the industry together to explore the challenges, and solutions, to meeting new ambitions on vessel emissions.

Sharing fuel usage data anonymously with IMCA is one-way Members can support our evidence-based engagement at the IMO on GHGs. 

With a unique use-case, our Members can be sometimes overlooked in wider discussions around vessel emissions.

  • IMO – Future Fuels website – A dedicated website aimed at the marine industry in the broadest sense, the online hub is a joint project of the Government of the Republic of Korea and the IMO aiming to support the regulatory decision-making at the IMO’s Marine Environment Protection Committee (MEPC).

To meet United Nations’ Sustainable Development Goal 13, which sets out the need ”to take urgent action to combat climate change and its impacts”, the International Maritime Organization (IMO) outlined its first Greenhouse Gas Strategy (GHG Strategy) for the maritime sector in 2018.

The IMO revised this Strategy in July 2023 with enhanced targets to tackle GHG emissions. As well as an enhanced common ambition to reach Net Zero GHGs by or around 2050, it also outlined a series of indicative checkpoints on alternative zero and near-zero fuels.

Four levels of ambition are outlined
  • Carbon intensity of the ship to decline through further improvement of the energy efficiency for new ships. Strengthening energy efficiency design requirements.
  • 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.
  • Uptake of zero or near-zero GHG emission technologies, fuels and/or energy sources to increase. To represent at least 5%, striving for 10%, of the energy used by international shipping by 2030.
  • 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 2050.
New indicative checkpoints set

The IMO GHG Strategy (July 2023) introduces indicative checkpoints to reach net-zero GHG emissions from international shipping, namely, to reduce the total:

  • Annual GHG emissions from international shipping by at least 20%, striving for 30%, by 2030, compared to 2008.
  • Annual GHG emissions from international shipping by at least 70%, striving for 80%, by 2040, compared to 2008.
How is this going to be achieved?

The 2023 IMO GHG Strategy foresees a basket of measures being developed in the mid-term to deliver the reduction targets comprised of both technical and economic elements.

  • Technical element: A goal-based marine fuel standard (GFS) regulating the phased reduction of marine fuel’s GHG intensity.
  • Economic element: Based on a maritime GHG emissions carbon pricing mechanism. No agreement has been reached but it is proposed to link directly to the GHG intensity fuel standard (GFS).

As was the case with the 2018 IMO GHG Strategy, it will be applicable for five years. It will be revised further in 2028 when even more stringent requirements are expected. IMCA continues to monitor developments and feed into discussions.

  • Fugro – Vessel conversion to green methanol fuel – The Fugro Pioneer is ready to be equipped with methanol engines after successfully converting the main components on board. Using green methanol reduces carbon emissions by more than 90% compared to conventional diesel.
  • Rem – Rem Offshore orders next generation vessel – Rem Offshore and Myklebust Verft have signed a contract for an Energy Subsea Construction Vessel (ESCV) with a 250-tonne crane. It will be the first of its kind that can perform heavy construction work in both offshore wind and subsea with net zero emissions.
  • RINA – CTV electrification project with Zevi Funding – UK-based crew transfer vessel (CTV) operator Tidal Transit has commenced the design and engineering phase of a project to deliver what is described as the world’s first retrofitted electric crew transfer vessel (E-CTV).

  • Maersk – 10 principles to decarbonise the OSV industry – A research paper by Maersk which offers operators and charterers practical ways to decarbonise. Although the paper takes as its point of departure offshore vessels, many of the principles outlined are applicable to the wider marine contracting industry.
  • World Ports Sustainability Program – Set up by the International Association of Ports and Harbors, the programme enhances and coordinates the sustainability efforts of ports worldwide and fosters international cooperation with partners across the supply chain.

  • ABB – CO2e calculator – Find out how much CO2e emissions you could reduce on your vessel by applying different technological solutions. Fill in the main operational details of your vessel and the calculator will estimate how many emissions you can expect to reduce.
