Project overview

Marine insurance plays a foundational role in the ocean economy because it enables shipowners to manage risk, invest, operate and recover from losses. Traditional hull and machinery insurance generally restores damaged vessels or equipment to their original condition. In a context of accelerating climate risks, tightening environmental regulation and an ageing fleet, that like-for-like model can perpetuate inefficiencies and delay the uptake of lower-emissions technology. Allianz Commercial's Marine Build Back Better Endorsement, released in May 2025 and expanded in April 2026, addresses this transition gap. The product provides additional financial support to hull and machinery clients who repair or replace damaged assets with more energy-efficient or lower-emissions alternatives after a loss event. The case is relevant to the regenerative blue economy because it shows how a mainstream financial product can shift from passive risk transfer towards proactive transition finance, using moments of asset repair and replacement to accelerate decarbonization across the maritime sector.

Approach

The endorsement changes the financial signal attached to post-loss repair decisions. To qualify, the insured must demonstrate that the repair or replacement improves vessel efficiency or reduces emissions by at least 5%. This can be achieved through increased energy efficiency, reduced carbon dioxide-equivalent emissions per unit of energy or an overall reduction in carbon emissions. The endorsement covers up to the lesser of 50% of the original loss value or 50% of the incremental costs associated with decarbonization measures, capped at $3 million based on fleet size. This means that an insured event, which would traditionally trigger restoration to pre-loss condition, can instead become a structured opportunity to upgrade assets. A range of existing technologies can support compliance with the criteria, including more efficient propulsion systems, advanced hull coatings that reduce drag, hybrid or alternative fuel systems and digital optimization tools. Many of these solutions are already technically viable but face adoption barriers linked to upfront cost and fragmented incentives. By embedding them into insurance coverage, Allianz helps bring decarbonization measures into routine operational and capital expenditure decisions. The mechanism does not require shipowners to wait for a new policy mandate or separate transition financing facility; it uses a recurring point of investment within the existing insurance relationship to encourage better environmental performance.

Business and economic value

The wider significance of the endorsement is that insurance becomes a proactive lever for sector transition, not only a tool for loss recovery. Post-loss reconstruction is a repeated investment moment across the global fleet. Redirecting even a portion of these repairs towards better efficiency, lower emissions and state-of-the-art technology can create steady, compounding gains over time. For shipowners, the product can reduce the additional cost of choosing a cleaner or more efficient option at the moment when assets already need repair or replacement. For insurers, it creates a pathway to align risk management with future resilience by reducing exposure to outdated, inefficient or higher-emitting assets. For ACT Ocean, the case illustrates an important lesson: insured events and asset renewal moments are underused financial levers. Embedding efficiency, emissions or nature criteria into standard coverage can convert routine replacement into transition finance for blue and green technology at scale, without relying solely on new capital or regulation. The model is especially relevant for a regenerative ocean economy because it shows how existing financial architecture can be redesigned to reward better future performance, rather than simply restoring the past.
