UCL Shipping and Oceans Research Group on Thursday (27 August) said new research has suggested that 10% of international shipping emissions occur within port areas globally. 

The finding offered hope that these emissions can be effectively mitigated via electrification technologies such as cold ironing at berth, switching to battery electric propulsion whilst idling or manoeuvring at port and converting vessels engaged with short-sea routes to battery-operated electric vessels. 

Presented as an interactive tool on the UCL Shipping and Oceans Research Group website, the ‘Shipping GHG Emissions Explorer’ aims to improve the evidence base supporting IMO negotiations due to resume next week on the adoption of the Net Zero Framework (NZF). 

Built using a dataset of 1.2 million voyages undertaken by over 43,000 unique vessels across a single year, the tool offers IMO delegations visibility on which of 575 million tonnes of CO2e emissions generated by international shipping can be attributed to their country’s economic activity.

James Stewart, Research Fellow in the Analytics of Energy and Transport at the UCL Shipping and Oceans Research Group, said: “Although imperfect, AIS-centred big data approaches have revolutionised our ability to understand key trends in the energy demands and GHG emissions associated with international shipping activity. The tool offers users the chance to benefit from this unprecedented clarity by downloading aggregate data directly from the platform, where interested parties are encouraged to explore and validate available statistics with any complementary datasets they may have access to.”

The tool offers energy demand and GHG emission statistics during port and voyage phases alongside disaggregation possibilities by vessel type, port and maritime trade partner, enabling users to explore key trends in international shipping activity. Future updates to the tool slated for release in September will provide users with additional statistics on state-level seaborne trade volumes and potential economic impacts of the proposed amendments to the IMO NZF ahead of their potential for adoption later in  the year.

Yoseph Ismail, Research Assistant at the UCL Shipping and Oceans Research Group, said: “Having the ability to breakdown international voyages by their ‘In port’ and ‘In voyage’ emissions has given us significant insight into what benefits electrification in port could bring. Our granular approach has allowed us to discover key trends in the country data. 

“For instance, 7 out of 10 countries in Latin America/Caribbean and 8 out of 10 in East Asia Pacific that have the highest in port emissions are small island nations. These countries emissions, are all well above global and regional averages, and often above 20%. Further analysis into the reasons for this could go a long way towards finding the most cost-effective solutions to bring down emissions.”

Baltic Workboats recently said a new 38-metre multi-purpose workboat, KRATT, built for the Estonian State Fleet, has been christened at its Nasva shipyard in Saaremaa on 12 August. 

KRATT is Estonia’s first large workboat to use biomethane as its primary fuel and is also equipped with a 400 kWh battery bank for electric propulsion. 

On biomethane, the vessel can travel up to 1,000 nautical miles at a speed of seven knots. On battery power, it can operate for up to two hours at five knots. The battery bank also allows the vessel to use electric power for up to ten hours while at anchor, reducing the need to run auxiliary engines as well as fuel consumption, emissions and noise levels.

From autumn, the vessel will carry out a wide range of maritime tasks in Estonian waters, from buoy handling and fairway maintenance to marine research, pollution response and rescue operations.

According to Andres Laasma, Director General of the Estonian State Fleet, the gradual renewal of the state-owned fleet is essential to ensure the country’s ability to carry out its maritime duties.

“Our main workboats today are on average 30-40 years old, and maintaining their reliability is becoming more difficult and costly year by year. The new workboat KRATT will help ease this situation, as it is a multi-purpose vessel capable of performing a wide range of tasks,” Laasma said.

KRATT is the first major workboat ordered by the state in the past ten years.

The Marine Energy Transition Forum (METF) 2026 will bring together leading voices from across the global maritime sector on 11 November 2026 at Norton Rose Fulbright, London.

The forum will tackle one of shipping’s most pressing challenges: how to overcome the fuel, technology and infrastructure barriers that continue to slow the industry’s transition to net-zero emissions.

Under the theme “Reframing the maritime decarbonisation roadmap: addressing fuel, technology and infrastructure bottlenecks,” the one-day forum will provide a platform for shipowners, fuel suppliers, technology developers, ports, policymakers and financiers to examine the practical steps needed to accelerate progress while maintaining commercial competitiveness.

As the maritime industry navigates an increasingly complex regulatory and commercial landscape, METF 2026 will focus on delivering practical insight into the challenges—and opportunities—shaping the next phase of the energy transition.

The conference programme will explore five key themes:

• The effectiveness of current regulatory frameworks and policy measures, including regional and international initiatives driving maritime decarbonisation.
• Progress in developing a resilient multi-fuel future, examining investment, fuel availability, supply chains and infrastructure.
• The commercial readiness of emerging technologies, including alternative propulsion systems, vessel optimisation, batteries, carbon capture, wind propulsion and digital solutions.
• Building a supportive business environment for energy transition companies, with discussions covering finance, innovation, scaling businesses and market development.
• The evolving role of ports as critical enablers of shipping’s energy transition through new fuel infrastructure, shore power and energy cluster development.

METF 2026 is designed to encourage open discussion between every part of the maritime value chain, recognising that collaboration across fuel producers, shipowners, ports, technology providers, investors and policymakers will be essential if global decarbonisation ambitions are to be achieved.

The event will feature expert speakers, panel discussions and extensive networking opportunities, enabling delegates to exchange ideas, develop partnerships and gain practical insight into the strategies shaping the future of maritime energy.

Registration for METF 2026 is now open. Further information and registration can be found here.
