Climate-Risk Disclosure for Maritime and Coastal Assets

Climate-Risk Disclosure for Maritime and Coastal AssetsAligning Ports and Governments with TCFD, ISSB and Emerging UK/EU Standards

Climate risk has shifted from a peripheral environmental concern to a material financial, operational and governance issue for maritime infrastructure. Caribbean port authorities, terminal operators, shipping companies and coastal asset owners now face increasing pressure from international financiers, insurers, global shipping lines, logistics partners, investors and auditors to disclose climate‑related risks in a manner that is credible, decision‑useful and aligned with international standards. This pressure is driven both by intensifying physical climate impacts and by evolving regulatory expectations in major trading and financing jurisdictions, particularly the United Kingdom and the European Union.

In this short video, Amaya Emmanuel, Legal & Business Support Specialist, explains why climate‑risk disclosure has become strategically unavoidable for Caribbean ports and coastal infrastructure. She outlines how global standards such as ISSB and TCFD now shape the expectations of lenders, insurers and logistics partners, and discusses what a proportionate, region‑appropriate approach to disclosure looks like for small island states.

Climate-Risk Disclosure for Caribbean Ports

The Expanding Influence of UK, EU and ISSB Disclosure Regimes

Although UK and EU climate‑risk disclosure rules do not directly legislate for Caribbean states, their influence is transmitted through financing, insurance and supply‑chain relationships. Regulated companies, lenders and insurers in these jurisdictions must assess and disclose climate risks across their global operations. Caribbean ports become indirectly subject to these expectations whenever they seek international finance, rely on insurers or reinsurers headquartered in Europe, participate in EU‑facing logistics chains or operate under public‑private partnerships with foreign sponsors. The practical effect is that climate‑risk disclosure becomes a condition of access to capital, coverage and commercial relationships.

The regulatory landscape has also evolved. The International Sustainability Standards Board (ISSB) has now formally absorbed the TCFD framework, and global convergence is occurring around IFRS S2 as the authoritative climate‑disclosure standard. TCFD remains the conceptual foundation, but ISSB standards now represent the operative benchmark for global comparability. This shift strengthens the expectation that ports and coastal infrastructure will align with internationally recognised disclosure practices, even in the absence of domestic legislation.

Escalating Physical Climate Impacts in the Caribbean

The urgency of credible disclosure is reinforced by the region’s escalating exposure to physical climate hazards. Islands such as Jamaica, The Bahamas, Barbados, Saint Lucia, Grenada, Antigua and Barbuda, and Saint Vincent and the Grenadines have experienced severe coastal erosion, storm surge and repeated hurricane‑related damage. Events such as Hurricanes Melissa in 2025, Beryl, Dorian and Irma have demonstrated the scale of operational disruption and economic loss that climate‑driven events can impose on ports, logistics corridors and coastal communities. These impacts have transformed climate risk from a theoretical concern into a material and recurring operational reality.

TCFD and ISSB as the Global Baseline for Climate‑Risk Disclosure

The TCFD framework, now embedded within ISSB’s IFRS S2 standard, requires organisations to disclose climate‑related risks and opportunities across four pillars: governance, strategy, risk management, and metrics and targets. For Caribbean maritime and coastal assets, this requires a fundamental re‑orientation of how climate risk is understood and managed. Hurricanes, storm surge, heat stress and long‑term sea‑level rise must be treated as financial risks capable of impairing asset value, disrupting operations and increasing insurance costs. Transition risks, including evolving emissions regulations, carbon‑pricing mechanisms and shifting customer expectations for low‑carbon logistics, must also be incorporated into strategic planning.

Governance expectations require clear board‑level oversight of climate issues, supported by management structures that integrate climate considerations into capital planning, maintenance schedules and emergency preparedness. Strategic disclosure demands structured scenario analysis that assesses how different climate pathways could affect port operations, asset lifespan and revenue streams. ISSB standards now require greater transparency regarding the assumptions and methodologies used in scenario analysis, even where quantification remains limited. Risk management disclosures must demonstrate that climate risks are integrated into existing enterprise risk frameworks rather than treated as standalone environmental issues. Metrics and targets require decision‑useful indicators that extend beyond emissions reporting to include hazard exposure, operational downtime and resilience investment needs.

Structural Challenges Facing Caribbean Ports

Caribbean ports face distinctive challenges in meeting these expectations. Many are state‑owned or operate under concession agreements, creating fragmented responsibility for disclosure. Technical capacity for climate scenario analysis, geospatial hazard mapping and data management is often limited. Data relevant to climate‑risk assessment is frequently dispersed across agencies, and the cost of external assurance can be prohibitive for small jurisdictions. These constraints make it unrealistic to replicate the depth of reporting expected of large listed companies in mature capital markets. A proportionate and region‑appropriate approach is therefore essential.

A Practical Pathway for Caribbean Adoption

A credible pathway for Caribbean adoption begins with embedding climate‑risk governance at the board and ministerial levels. Governments should issue policy guidance that encourages or requires TCFD‑ and ISSB‑aligned reporting for strategically significant maritime assets, particularly where public funds or guarantees are involved. Ports must move beyond generic statements of vulnerability and undertake structured scenario analysis that considers both physical and transition risks. Integrating climate risk into enterprise risk management systems can strengthen both resilience and regulatory credibility. Progress on metrics and targets will require regionally appropriate indicators and improved data sharing across ports, insurers and meteorological agencies.

The Case for a Regional Climate‑Risk Disclosure Framework

A regional approach offers significant advantages. Rather than each island independently commissioning climate scenario models, asset registries and disclosure templates, CARICOM states and regional institutions could develop shared baselines, common definitions of material climate risk, standardised minimum disclosure tables and interoperable GIS layers. A coordinated approach would reduce duplication, lower costs and improve consistency across the region. Over time, this could support the establishment of a Caribbean climate‑risk disclosure facility capable of producing shared analytical outputs and offering technical assistance. Such a framework should not diverge from international standards but instead map explicitly to TCFD and ISSB requirements to ensure global comparability while reflecting Caribbean hazard realities and capacity constraints.

Insurance as a Key Transmission Mechanism

Insurance remains one of the most significant channels through which Caribbean states are indirectly subjected to TCFD‑ and ISSB‑aligned expectations. Insurers and reinsurers operating across the UK and EU increasingly rely on climate‑risk disclosures to assess exposure, price premiums and determine coverage terms for ports, terminals and coastal infrastructure. The market has moved beyond general reliance on disclosures toward the use of probabilistic catastrophe modelling and asset‑level climate analytics. Where disclosure is inadequate or inconsistent, underwriters may treat risks as unquantified and therefore higher, leading to increased premiums, tighter deductibles, restricted limits or exclusions for climate‑related losses. Conversely, credible and standardised disclosure can improve insurability by reducing informational asymmetry and demonstrating sound governance and adaptation planning.

Recent Caribbean Initiatives Supporting Climate‑Risk Disclosure

Several recent initiatives demonstrate that the region is already moving toward more structured climate‑risk disclosure. In 2024, the Caribbean Development Bank launched a regional climate‑risk assessment and disclosure support programme designed to help ports and critical infrastructure operators align with ISSB and TCFD expectations. This programme includes technical assistance for scenario analysis, hazard mapping and the development of climate‑risk governance frameworks. In 2025, the Port Authority of Jamaica initiated a climate‑resilience and disclosure pilot in partnership with international insurers and a global engineering consultancy. The project involves asset‑level vulnerability assessments, climate‑adjusted maintenance planning and the development of a TCFD‑aligned disclosure template intended to serve as a model for other Caribbean ports.

In April 2025, the Inter‑American Development Bank, IDB Invest and the IFRS Foundation formalised a strategic partnership to accelerate the adoption of the IFRS Sustainability Disclosure Standards across Latin America and the Caribbean. The initiative includes capacity building for regulators, technical assistance for public and private institutions, and the development of regional tools to support implementation. This partnership signals growing regional momentum toward ISSB‑aligned disclosure and reinforces the expectation that Caribbean ports and coastal infrastructure will increasingly be assessed against global sustainability reporting standards.

Conclusion

Alignment with TCFD, ISSB and emerging UK and EU standards should not be viewed as an administrative burden. For Caribbean maritime and coastal assets, credible climate‑risk disclosure is becoming strategically unavoidable. The choice is not whether to disclose climate risk, but whether to do so proactively in a manner that is proportionate, regionally coordinated and aligned with international expectations, or reactively under external pressure from financiers, insurers and supply‑chain partners. When implemented effectively, climate‑risk disclosure strengthens resilience, improves access to capital, stabilises insurance terms and supports long‑term operational continuity across the region’s ports and coastal infrastructure.
