Global majors reach historic deal on cutting shipping emissions
After years of intense negotiations, many of the world's largest shipping nations have reached a landmark deal to cut greenhouse gas emissions from global shipping, setting mandatory fuel standards and introducing an industry-wide carbon pricing mechanism.
The framework – agreed during the UN International Maritime Organisation (IMO) Marine Environment Protection Committee – aims for net-zero emissions from the sector by 2050 and will be formally adopted in October before coming into force in 2027.
They will apply to large ocean-going vessels over 5,000 gross tonnage, which collectively account for 85% of carbon dioxide emissions from the marine shipping fleet.
IMO Secretary-General Arsenio Dominguez hailed the breakthrough after a 10-year deadlock, emphasising the collaborative spirit that led to the deal.
"The approval of draft amendments to Marpol Annex VI mandating the IMO net-zero framework represents another significant step in our collective efforts to combat climate change, to modernize shipping and demonstrates that IMO delivers on its commitments," he stated.
Marpol Annex VI refers to provisions in the International Convention for the Prevention of Pollution from Ships, specifically addressing air pollution.
It already includes mandatory energy efficiency requirements for ships and has 108 Parties covering roughly 97% of the world's merchant shipping fleet by tonnage.
The framework introduces a dual approach: a global fuel standard that will progressively lower the annual greenhouse gas fuel intensity of marine fuels, and a greenhouse gas pricing mechanism requiring high-emitting ships to pay for their excess pollution, said experts.
Under the new system, ships that exceed emissions limits will need to acquire remedial units to offset their excess pollution, they stated.

Global trade complexity drives innovation in maritime solutions
As maritime transportation continues to be a key propeller of global trade, it has an indispensable position in the global economy. Over the years, the industry has entered into a new era defined by rapid integration of advanced technologies and digitalisation. These changes are evidently reshaping maritime operations, especially in the area of navigation, communication and automation. These technologies are not only offering unprecedented levels of efficiency, but also are becoming a necessary factor for the industry players' survival in a highly competitive and regulated environment. According to the World Trade Organization (WTO), global trade is expected to continue expanding in 2025 and 2026, with merchandise trade volume gradually increasing in line with global GDP growth. Trade in commercial services is projected to grow at an even faster pace. The Middle East is also anticipated to see a rise in export volumes. This increasing trade volume underscores the need for advanced maritime solutions capable of handling greater complexity and ensuring efficient vessel management, safety, and environmental compliance. The growing complexity of environmental regulations, such as the IMO's Global Sulphur Cap which began in 2020, have forced shipowners to use cleaner and efficient technologies to reduce emissions. Amidst this, advanced navigation and communication systems aid industry players with precise and real-time data that enables them to navigate the tough routes with great safety and accuracy. For instance, GPS, which was launched between 1978 and 1985 with 11 satellites, now has about 24 satellites that orbit the Earth and send radio signals from space, further signifying the increasing demand for advanced navigation systems. In the current scenario, sailors are well-trained to handle modern navigation equipment, as vessels are equipped with advanced systems that provide accurate voyage data. For example, the gyrocompass provides a reliable directional source by accurately referencing the Earth's axis of rotation. As against the magnetic compass, it determines direction without being affected by external magnetic fields. Another key tool is Marine radars, which detect obstacles along the ship's path to prevent collisions. These radars, using microwave propagation, gather data beyond the human eye's reach, ensuring adherence to the International Regulations for Preventing Collisions at Sea (COLREGs) of 1972. Marine radars rely on S-band and X-band systems, which detect targets from long distances, including islands, icebergs and other floating objects, providing essential information to avoid collisions. It uses rotating antennas to scan the surroundings of the vessel. Complementing radar systems, the magnetic compass, which operates with the Earth's magnetic field, serves as the primary direction indicator on the bridge panel. Similarly, the Automatic Radar Plotting Aid (ARPA) is a key feature of modern radar systems that continuously monitor the ship's surroundings by detecting targets including ships, boats and stationary objects. It collects and provides data on their speed and course, helping prevent collisions. The automatic tracking system displays target information in both graphical and numerical formats, further enhancing safety during navigation. Additionally, the echo sounder, a navigation instrument used for nearly a century, measures the depth of water beneath a ship using sound wave transmission. Meanwhile, the Electronic Chart Display and Information System (ECDIS) simplifies locating a ship's position on navigational charts, offering greater accuracy. Modern vessels use marine digital voyage and route planners to avoid harsh weather and other obstacles, calculating the safest and cheapest routes.

GCC transport, logistics can cut carbon emissions by 20pc: Strategy&
GCC countries have a critical opportunity to advance their ambitious net-zero commitments by transforming their transport and logistics (T&L) sector, according to new research from Strategy& Middle East, part of the PwC network. Representing a quarter of global greenhouse gas emissions, the sector offers a critical opportunity to drive impactful change. According to the analysis, targeted measures could reduce regional carbon emissions across T&L activities, by 20% to 40%. With all GCC nations committed to achieving net-zero emissions by 2050 or 2060, the logistics sector's environmental impact cannot be overstated; its influence extends beyond its own footprint. As an enabler of nearly all economic sectors, from manufacturing to retail, logistics decarbonization offers an unparalleled multiplier effect. The fact that T&L is embedded within so much of the region's economy gives it a potential that exceeds its already large direct footprint. "Globally and across the GCC, transport and logistics stands out as a high emission sector that plays a pivotal role in enabling and influencing various parts of economies," said Maha Raad, Partner at Strategy& Middle East. "Clearly, decarbonization of the sector is of critical importance, and there is opportunity to initiate this at domestic level, with the aim of creating strong impact on decarbonization agendas," she added. For the GCC's fast-growing, dynamic markets, there is broad awareness that without effective near-term action, carbon emissions are projected to increase instead of decline, threatening regional sustainability efforts. The new research from Strategy& Middle East underscores the need for a paradigm shift in logistics operations, which moves beyond incremental improvements, toward innovative practices that prioritize sustainability without comprising efficiency or economic growth. A framework for change Achieving meaningful decarbonization in the GCC's T&L sector hinges on a collaborative effort among governments, industry leaders, and other stakeholders. A tailored change framework is needed, with distinct measures for both 'cross-border' and 'domestic logistics.' For cross-border logistics - specifically air and sea transport - emission targets are being set by supranational bodies such as the IMO and IATA. This requires GCC countries to adapt their regulations, such as vessel emission limits, and adjust or update infrastructure (e.g. alternative fuel bunkering in ports), to align with international standards, and potentially play a leading role in the global scene to accelerate the future of fuels agenda. In domestic logistics, examples of shifts in practices include moving from the traditional just-in-time (JIT) model to a balanced supply chain management approach; transitioning from delivery schedules that prioritize speed to capacity optimization; and adopting multimodal delivery systems to integrate greener transportation modes. The transition from JIT, which prioritizes efficiency and speed but often results in higher emissions, to a balanced approach allows for a recalibration of operations to achieve both economic and environmental goals. Similarly, optimizing capacity through strategies such as dynamic routing and load consolidation addresses inefficiencies while reducing underutilized vehicle trips. Integrating multimodal systems, including expanded use of rail and maritime transport in countries like Saudi Arabia and the UAE, offers significant potential to reduce long-haul emissions while driving operational savings. These shifts are vital to achieving sustainable logistics. "For the GCC, composed of fast-growing, dynamic markets, meeting sustainability targets will be even more of an uphill battle than in other regions," said Hamza El Mounhi, Principal at Strategy& Middle East. "However, with the right focus on technology, innovation, and collaboration, the region can set a global standard for decarbonized logistics," he added. The role of stakeholders At a policy level, governments can be critical to the success of this transformation. Policymakers can enforce international sustainability standards, incentivize green practices and green fleet deployments, and define acceptable emissions standards, according to the report. On the infrastructure front, investments in green fuels and technologies, such as hydrogen and biodiesel, further present an opportunity to position the GCC as a global leader in sustainable logistics innovation. Private sector stakeholders, including carriers, logistics service providers, and cargo owners, are equally pivotal. Carriers and logistics providers must adopt international standards, reconfigure logistics networks for greater efficiency, and deploy green technologies such as electric vehicles, it stated. Cargo owners can embrace predictive analytics to optimize inventory management and operations while rethinking rapid delivery expectations to balance sustainability with performance. Consumers also play a significant role in the broader shift toward greener logistics. By choosing products and services from companies that prioritize sustainable practices, their decisions amplify industry-wide efforts to reduce carbon emissions. The GCC's logistics sector has the potential to become a global leader in sustainability, contributing not only to the region's net-zero goals but also to broader economic resilience and competitiveness. With decisive action and collaboration, the sector can deliver transformative outcomes for the environment and the economy. 'As we look to the future, the path to net zero is not just about incremental change. It requires a rethinking of traditional approaches, driven by innovation and underpinned by collective commitment," said Raad.
