Financing with respect: How blue finance can evolve through Indigenous stewardship

This is part of a 6-article series. You’re reading Part 2. Here, you can find Part 1.

Blue finance has grown from a niche concept into a rapidly expanding ecosystem of financial instruments that promise to mobilize capital for ocean protection. Blue bonds, blended-finance vehicles, plastic credits, and outcomes-based contracts are reshaping the conversation about how to fund marine conservation at scale.

Capital is moving; markets are forming; and the architecture of a new ocean economy is emerging.

And yet one foundational question remains unanswered: who defines the terms and values that guide this growing financial infrastructure?

As with the early phases of green finance, innovation is advancing more quickly than the governance frameworks needed to anchor it. While deal structures proliferate, Indigenous communities — whose stewardship systems have governed marine and riverine ecosystems for millennia — are often engaged late or superficially.

This gap is not simply ethical. 

It is a structural risk that shows up in delayed implementation, community resistance, and long-term fragility of financial commitments. Instruments designed without Indigenous governance tend to become brittle, while those built through shared authority are far more durable.

This article explores how four mechanisms at the heart of blue finance — blue bonds, blended finance, plastic credits, and outcomes-based structures — evolve when viewed through Indigenous stewardship principles.

Blue bonds: Scale, promise, and the need for consent

Blue bonds and debt conversions in the Seychelles, Belize, Ecuador, and elsewhere have demonstrated the power of sovereign instruments to unlock conservation outcomes and fiscal space. But the key question is not only how much capital is mobilized — it is who has the authority to commit marine territories to long-term covenants.

Across many Indigenous coastal regions, governance is organized not through modern bureaucracies but through hereditary responsibilities, customary law, and collective stewardship duties. When governments commit lands and waters without meaningful consent from these authorities, the legitimacy of the entire instrument is weakened.

A blue bond aligned with Indigenous governance must incorporate:

1. Free, prior, and informed consent (FPIC) — not as consultation, but co-governance.

2. Benefit-sharing that strengthens local stewardship institutions.

3. Indicators rooted in both Western science and Indigenous definitions of ecological health.

Without these elements, blue bonds risk repeating earlier extractive models under a conservation label. With them, they can reinforce the systems that have safeguarded marine ecosystems for generations.

Blended finance: De-risking the right things

Blended finance is often described as a tool to “de-risk” private investment. But from an Indigenous perspective, the largest risks are rarely financial. They are governance risks: loss of decision-making power, externally imposed metrics, erosion of cultural authority, and exclusion from benefit flows.

A more grounded model would reframe blended finance around relational alignment, not investor de-risking. This means:

• Recognizing Indigenous governance bodies as anchor partners, not downstream “stakeholders”
• Embedding customary governance principles directly into financial agreements
• Funding not only projects but the stewardship institutions that uphold ecological integrity

Such an approach does not slow capital deployment — it strengthens it by reducing the implementation failures that occur when community authority is sidelined.

Plastic credits: Preventing a new form of impact extractivism

Plastic credits are emerging quickly as a mechanism to monetize verified recovery or removal. They can accelerate investment in waste infrastructure across key river systems and coastlines.

But they also raise fundamental questions:

• Who sets the value of environmental labor?
• Who owns and controls the data that determines credit issuance?
• Who benefits from value created on the ground?

In many coastal and riverine regions, waste-picking and plastic-recovery work is informal, dangerous, and chronically undervalued; unless communities own the monitoring systems, credit markets risk reproducing this inequity.

Indigenous communities often view stewardship as a relational obligation, not a commodity. For plastic credits to reinforce — rather than distort — these obligations, they must integrate:

• Community-owned MRV systems
• Data sovereignty protocols
• Fair pricing informed by local definitions of environmental labor
• Cultural indicators alongside tonnage-based metrics

If designed without these safeguards, plastic credits risk becoming a new form of impact extractivism. If designed with them, they can support the custodians whose labor and knowledge stabilize ecosystems.

Outcomes-based structures: Measuring what truly matters

Outcomes-based contracts (OBCs) appeal to investors and philanthropies seeking measurable results. Yet measurement itself is never neutral — it reflects epistemologies, power, and priorities.

Indigenous knowledge systems define success through interdependence: ecosystem health, cultural continuity, food security, and the strength of community governance.

These forms of value rarely align neatly with short-term indicators or investor reporting cycles.

An outcomes-based structure informed by Indigenous stewardship would:

• Co-create indicator frameworks with Indigenous knowledge holders
• Pair ecological metrics with cultural and relational indicators
• Respect seasonal and ceremonial rhythms in project design
• Reward improvements in governance strength, not solely biophysical outputs

In this model, outcomes-based finance becomes a tool for reinforcing long-standing stewardship systems rather than reducing them to narrow technical indicators.

The path forward: Stewardship as the operating system

Across all four mechanisms, a simple truth emerges: blue finance cannot achieve legitimacy or lasting ecological outcomes without centering Indigenous governance.

Indigenous stewardship principles — reciprocity, respect, accountability, long-termism — are not barriers to innovation. They are the conditions that allow innovation to take root.

Rather than designing around Indigenous authority, blue finance should grow through it.

And this leads naturally to the next question in this series:

If financial instruments are evolving to reflect Indigenous stewardship, how must ocean governance itself evolve?

The next article in this series will explore that question directly: what would ocean policy look like if Indigenous leadership, customary authority, and community-led data governance shaped not only conservation outcomes but the rules of the ocean economy itself?
