Carbon Management

Carbon management focuses on addressing residual emissions through a combination of natural systems, engineered solutions, and resource efficiency strategies. While electrification, operational improvements, and alternative fuels can significantly reduce emissions, some emissions are difficult to eliminate entirely, particularly in complex port and maritime systems. Carbon management approaches provide mechanisms to mitigate these remaining emissions and support the achievement of net zero targets.

This practice includes nature-based solutions such as habitat banking and blue carbon initiatives, as well as engineered approaches including carbon capture, utilization, and storage. In addition, circular economy strategies, such as material reuse and waste-to-energy systems, can reduce emissions associated with resource consumption and waste generation. Carbon offset programs and lifecycle-based approaches further support emissions management by accounting for emissions across value chains and enabling compensation where direct reductions are not feasible.

Carbon management complements other decarbonization practices by addressing emissions that remain after primary reduction measures have been implemented. It is closely linked to energy infrastructure, future fuels, and clean energy logistics, as these systems may generate residual emissions that require mitigation. As ports transition toward low-carbon operations, carbon management plays a critical role in achieving long-term climate objectives and supporting broader sustainability outcomes.

Carbon management encompasses a range of strategies aimed at reducing, capturing, or offsetting residual greenhouse gas emissions that cannot be eliminated through direct decarbonization measures. In port environments, these residual emissions may arise from hard-to-abate activities, including certain vessel operations, industrial processes, and supporting logistics systems. As ports progress toward electrification and low-carbon fuels, carbon management becomes increasingly important as a complementary approach to achieve net zero emissions. This includes both engineered solutions, such as carbon capture, utilization, and storage (CCUS), and nature-based approaches, such as blue carbon and habitat restoration.

As a core thematic area, carbon management addresses emissions that remain after primary reduction strategies have been implemented, providing a pathway to close the gap toward net zero. Engineered solutions such as CCUS involve capturing carbon dioxide emissions from industrial or energy processes and either storing them permanently or reusing them in other applications.

These technologies are being explored in maritime and port contexts, particularly where integration with industrial clusters or energy systems is feasible. Nature-based solutions, including blue carbon initiatives such as mangrove restoration, seagrass protection, and coastal wetland management, can sequester carbon while also providing additional environmental benefits such as biodiversity enhancement and coastal protection. Circular economy practices further contribute by reducing emissions associated with material use, waste generation, and energy consumption.

Globally, carbon management strategies are gaining attention as part of broader decarbonization pathways. Reports from international organizations highlight the importance of carbon dioxide removal and CCUS in achieving long-term climate targets, particularly for sectors where emissions are difficult to eliminate (IPCC, 2024). In parallel, development institutions such as the World Bank emphasize the role of climate change mitigation, nature-based solutions, and carbon capture, utilization and storage (CCUS) projects in supporting sustainable infrastructure and climate resilience (World Bank, 2025). In port and maritime contexts, early applications of carbon capture technologies and blue carbon initiatives are being explored, although large-scale deployment remains limited and subject to ongoing research, policy development, and economic considerations.

Innovations in carbon capture are emerging as possible complements to other practices (such as electrification and alternative fuels in carbon management). Vycarb states that its technology (Vycarb, 2026) stores CO₂ on site by converting CO₂ into stable bicarbonate stored in water, which the company describes as permanent, measurable storage with minimal infrastructure requirements. The company states its system can be installed with little new infrastructure, but it has not yet been deployed at ports. In parallel, onboard carbon capture systems allow vessels to capture emissions during operation and offload them at ports for storage or reuse, creating a full carbon value chain. Such innovations could help ports address residual emissions, subject to energy penalties and accounting boundaries, and transition toward net zero operations.

In DMCs, carbon management presents both opportunities and challenges. The region has significant potential for blue carbon initiatives due to its extensive coastal ecosystems, including mangroves and wetlands, which can serve as effective carbon sinks. At the same time, ports located within or near these ecosystems can play a role in supporting conservation and restoration efforts through habitat banking and integrated coastal management strategies. However, the implementation of engineered solutions such as CCUS may be constrained by technical complexity, infrastructure requirements, and cost. Carbon markets and offset programs may provide additional pathways for ports to manage residual emissions, although these require robust governance frameworks and credible monitoring systems to ensure environmental integrity.

Successful implementation of carbon management strategies requires enabling conditions that support both technical and institutional development.

• Policy frameworks and regulatory mechanisms are critical to define accounting methodologies, establish carbon pricing or market systems, and support investment in carbon management solutions.
• Advances in technology and research are needed to improve the feasibility and cost-effectiveness of CCUS and carbon removal approaches.
• Collaboration among stakeholders, including governments, port authorities, industry, and environmental organizations, is essential to develop integrated solutions that balance economic and environmental objectives.
• In addition, transparent monitoring, reporting, and verification systems are required to ensure credibility and effectiveness.

Key challenges include high costs, uncertainty in long-term performance, and the need to prioritize emissions reduction before relying on offsets. Addressing these challenges through coordinated strategies and phased implementation will be essential to integrating carbon management into port decarbonization frameworks.
