The Ørsted Blue Bond
In 2023, the world's largest offshore wind company became the first energy firm to issue a blue bond. What the money actually funded says something about where corporate blue finance is heading.
Offshore wind projects are large, complex undertakings. They are built in open ocean environments, far from shore, where construction, installation, and maintenance depend on weather, seabed conditions, and access. These projects require significant upfront capital and are developed over long timelines, through multiple stages of permitting, engineering, and coordination. They also operate alongside existing uses of the ocean. Shipping routes, fisheries, and marine ecosystems all factor into how projects are planned and approved, and those considerations influence both timelines and cost. Financing in this context reflects those conditions: capital is committed over long periods, and assumptions about performance, maintenance, and operating conditions extend well beyond initial construction.
In June 2023, Ørsted, the world's largest offshore wind developer, became the first energy company to issue a blue bond: a five-year, €100 million private placement aligned with the International Finance Corporation's Guidelines for Blue Finance. The proceeds were not directed at building wind farms. They were allocated to marine biodiversity measures and to sustainable shipping, with reporting required to show how the funds were applied. That marked a notable step in the progression of blue finance, which until then had been led primarily by governments.
A corporate bond allows a company to raise funds from investors with a commitment to repay over a defined period, supported by the company's overall cash flow. In a standard corporate bond the funds are not tied to a specific use; they are applied across the company's operations and capital programs. The Ørsted bond is different in one respect: the use of proceeds was defined in advance and directed toward ocean-related activities, in this case restoring and protecting marine biodiversity affected by offshore development and supporting the shift to cleaner ocean shipping. Some of those uses do not generate direct financial returns. They relate to how projects are designed and how they operate within their surrounding environment. For bondholders, repayment does not depend on those specific activities producing cash flow; it depends on the company's overall financial position and its ability to meet its obligations.
Offshore wind sits behind all of this because of where Ørsted works. Its wind farms are constructed and operated within marine environments, which introduces considerations not present in land-based infrastructure. Foundation design, installation methods, and ongoing maintenance all depend on ocean conditions, and interactions with marine life and other ocean users are part of project planning and approval. The biodiversity measures the bond funds are tied directly to that reality: Ørsted has committed that all new renewable energy projects it commissions from 2030 will have a net-positive impact on biodiversity. The bond structure links capital to specific activities within the marine environment, including activities that generate no direct revenue, while repayment continues to rely on the company's overall cash flow. For Ørsted, this approach can support access to a broader group of investors and, in some cases, more favourable pricing. It also aligns the structure of financing with the conditions under which these projects are developed, where environmental requirements and long-term operating considerations are already part of delivery.
The example extends the application of blue finance beyond government issuers. It shows how a corporate borrower can use existing financing tools to direct capital toward defined activities, with conditions attached to how the funds are used, and it shows that the approach works in sectors where the connection to ocean systems is direct. Offshore wind is one such sector; similar considerations arise in shipping, ports, and other marine-related industries. The structure itself is not new. What is different is how it is used.
The Ørsted bond sits alongside earlier government issuances such as the Seychelles blue bond. Both link capital to defined uses, but they operate in different contexts. The Seychelles bond is tied to national policy and resource management; the Ørsted bond is tied to project development and corporate activity. That brings the same approach into areas where capital is deployed at the level of individual projects and operating assets.
The bond does not resolve the broader pressures affecting ocean systems. It provides one example of how financing can be structured to reflect those conditions. As more activity takes place in the ocean, capital and ocean conditions are more tightly linked, and decisions about how projects are financed influence how they are designed and how they operate within marine environments.
