The Global Centre for Maritime Decarbonisation (GCMD) on Wednesday (11 June) said a survey found 77% of shipowners and operators now consider achieving net zero a high priority in their strategy, up from 73% two years ago.

This was among the findings of the second edition of the Global Maritime Decarbonisation Survey, jointly conducted by GCMD and Boston Consulting Group (BCG) between October 2024 and February 2025.

The survey gathered 114 responses from shipowners and operators across a range of vessel types, fleet sizes, and regions. While the survey was conducted before the International Maritime Organization’s (IMO) MEPC 83 session in April, its findings already reflected sustained commitment across the industry. The outcomes of MEPC 83—introducing new regulatory targets and incentives—are expected to reinforce these ambitions and further accelerate momentum.

Survey results show that 60% of respondents have now set net-zero targets (up from 54%), while the use of bio-blended fuels has more than doubled to 46%, and methanol use has increased from 3% to 6%. However, uptake of more nascent technologies—such as ammonia, wind-assisted propulsion systems, solar panels, super-light ships, and air lubrication—remains limited.

The survey also reflects the industry’s desire for policies and regulations to create a level playing field. Nearly three-quarters of respondents identified either compliance measures or financial incentives as the most important policy objectives. A level playing field will ensure that early adopters are not competitively disadvantaged on cost and stakeholders with limited resources can benefit from financial support to overcome economic barriers.

The survey also gathered insights from key bunkering ports, whose support is critical for maritime decarbonisation. Most surveyed ports have roadmaps and dedicated teams focused on initiatives to facilitate maritime decarbonisation, and all of them, namely Port of Antwerp-Bruges, Port of Long Beach, Port of New York and New Jersey, Port of Rotterdam, and Port of Singapore, offer green incentives. 

A significant concern for ports, however, is the lack of demand certainty from shipping companies for both low-carbon fuels and Onboard Carbon Capture Systems (OCCS). This ‘chicken-and-egg’ dilemma hinders ports to take on the investment decision to develop the requisite infrastructure, though the recently introduced GHG pricing mechanism is expected to strengthen demand signals for low-carbon fuels.

Dr Sanjay C Kuttan, Chief Strategy Officer of GCMD, said, “Positive developments in maritime policy, especially from the IMO, which further tighten limits on GHG emissions, along with the increased ambitions voiced by survey respondents, are encouraging signals. Greater cooperation with the ports and pertinent stakeholders across the various value chains will be required to address challenges across the broader ecosystem. With the right investments and collaborative actions, the maritime industry can chart a course to a future where sustainable decarbonisation and commercial success can co-exist.

Anand Veeraraghavan, Managing Director and Senior Partner of BCG, said, “It is encouraging to see that even in the face of global uncertainties, the maritime industry’s decarbonisation ambitions remain intact and steadfast. The recent MEPC outcomes mark a pivotal step forward, sharpening demand signals with incentives for exceeding compliance goals and penalty mechanisms for shortfalls. Now is the time for the industry—both ships and ports—to build on this momentum.
