Can Green Finance Actually Protect Biodiversity?

Green finance has rapidly moved from a niche concept within sustainable investment to a major part of the global environmental agenda. Governments, development banks, corporations and investors are increasingly directing capital toward green bonds, sustainability-linked loans, conservation funds, nature-based solutions and emerging biodiversity markets. The underlying idea is straightforward: if financial decisions influence what businesses build, extract, produce and consume, then changing those financial incentives should also influence environmental outcomes. But biodiversity presents a much harder test than simply financing renewable energy or reducing carbon emissions. The central question is not whether money can be directed toward nature. It clearly can. The real question is whether green finance can change the economic forces that are driving biodiversity loss in the first place.

That distinction matters because biodiversity is not a single environmental problem with a single metric. It encompasses forests, wetlands, oceans, rivers, grasslands, soils, wildlife, plants, microorganisms and the complex relationships connecting them. A financial investment can reduce carbon emissions while damaging a habitat. A forest project can increase tree cover while reducing ecological diversity. A company can publish an impressive sustainability report while its supply chain continues to contribute to deforestation. Green finance therefore faces a much broader challenge than simply making capital more environmentally responsible. It has to demonstrate that financial decisions are contributing to healthier ecosystems, protecting species and reducing the pressures responsible for nature loss.

The Growing Biodiversity Financing Gap

The need for additional finance is enormous. The OECD estimates that global biodiversity-related finance currently stands at roughly US$78 billion to US$91 billion annually, while the resources required to meet international biodiversity goals are substantially higher. The Kunming-Montreal Global Biodiversity Framework has responded to this gap by setting a target to mobilise at least US$200 billion per year for biodiversity by 2030 from domestic and international, public and private sources. The framework also calls for international biodiversity finance to developing countries to reach at least US$30 billion annually by 2030. These targets recognise that governments and philanthropic organisations alone cannot provide all the capital required to protect and restore ecosystems at the necessary scale. (OECD)

The financing challenge exists partly because many of nature's most valuable services are poorly reflected in conventional markets. A healthy wetland can reduce flood risks, filter water, store carbon and support fisheries, yet those services may not generate a financial return comparable to converting the same land for construction. A standing forest can support biodiversity, regulate water systems and provide livelihoods, but clearing it for agriculture or timber may create immediate revenue. This creates a structural disadvantage for conservation. Green finance can potentially help correct that imbalance by making nature-positive activities more financially attractive, but doing so requires more than simply creating new investment products. It requires changing the underlying economics that determine whether protecting an ecosystem is more valuable than destroying it.

The Biggest Problem May Be the Money Already Flowing in the Wrong Direction

The biodiversity finance debate becomes considerably more complicated when existing financial flows are considered. The world is not merely failing to invest enough money in nature. Large amounts of capital are simultaneously supporting activities that contribute to environmental degradation. UNEP's State of Finance for Nature 2026 estimates that approximately US$7.3 trillion flowed into nature-negative activities in 2023, while only around US$220 billion was invested in nature-based solutions. This represents a profound imbalance. It means that increasing conservation finance without addressing the much larger financial flows supporting environmental destruction could produce only limited results. (UNEP)

This is why one of the most important elements of the Kunming-Montreal Global Biodiversity Framework is not simply its call for more biodiversity finance, but its emphasis on redirecting harmful financial incentives. The framework calls for the elimination, phase-out or reform of incentives that are harmful to biodiversity and sets an ambition to reduce such incentives by at least US$500 billion per year by 2030. The significance of this target should not be underestimated. Financing a forest restoration programme while simultaneously subsidising activities that encourage deforestation is economically contradictory. A more effective approach would address both sides of the equation: increase investment in protecting nature while systematically reducing the financial incentives that make its destruction profitable. (Convention on Biological Diversity)

Where Green Finance Can Make a Real Difference

When properly designed, green finance can provide resources for activities that are essential to biodiversity protection but often struggle to attract conventional investment. These include forest conservation and restoration, mangrove protection, wetland restoration, sustainable agriculture, regenerative land management, sustainable fisheries and nature-based infrastructure. Finance can also support businesses that generate income while maintaining ecosystem health, creating alternatives to economic activities that depend on environmental degradation. Blended finance can be particularly valuable because public or philanthropic capital can be used to reduce investment risks and attract private capital into projects that might otherwise be considered too uncertain or commercially unattractive.

The social dimension is equally important. Conservation becomes much harder when communities are expected to protect ecosystems without receiving meaningful economic benefits from doing so. A farmer facing poverty may have strong cultural or personal reasons to protect a forest, but those motivations cannot always compete with the immediate income available from clearing land. Properly structured finance can support alternative livelihoods, sustainable agriculture, community conservation and payments for ecosystem services, allowing people to derive economic value from maintaining natural ecosystems. This is particularly relevant across developing regions, including Africa, where conservation objectives frequently intersect with the need for employment, food security, infrastructure and economic development.

But a Green Label Does Not Guarantee Biodiversity Protection

One of the greatest risks facing the green finance industry is the assumption that environmental terminology automatically represents environmental performance. The word "green" has significant commercial value, but a green financial product is only as meaningful as the activities it finances and the standards used to evaluate them. A renewable energy project can reduce greenhouse gas emissions while affecting sensitive habitats if poorly located. A sustainable agriculture investment can improve one environmental indicator while creating pressure elsewhere. A company can also achieve impressive sustainability metrics in one part of its business while its broader supply chain continues to contribute to deforestation, pollution or habitat destruction.

Biodiversity makes this challenge particularly difficult because there is no single equivalent of carbon dioxide that can capture the condition of nature. Two forests can contain similar amounts of carbon while having dramatically different ecological characteristics. One could contain diverse plant communities, endangered species, intact habitats and functioning ecological relationships, while another could be a highly simplified plantation. A financial system focused too heavily on carbon therefore risks confusing climate benefits with broader environmental benefits. Green finance needs to recognise that climate-positive does not automatically mean biodiversity-positive, and that environmental investments must be evaluated according to the specific ecosystems and pressures involved.

Measurement Will Determine Whether Biodiversity Finance Is Credible

For biodiversity finance to become genuinely effective, investors need much stronger information about ecological outcomes. A credible project should establish the condition of an ecosystem before investment, identify the threats it faces and determine what would likely happen without the intervention. It should then measure whether the investment produced additional improvements and whether those improvements are likely to continue. This concept of additionality is particularly important because funding an activity that would have happened anyway does not necessarily represent a new biodiversity benefit. The more money enters nature markets, the more important it becomes to distinguish genuine ecological improvements from activities that simply generate attractive sustainability claims.

Nature-related financial disclosure is already developing in response to this challenge. The Taskforce on Nature-related Financial Disclosures, or TNFD, provides recommendations intended to help organisations identify, assess, manage and disclose their dependencies, impacts, risks and opportunities related to nature. This can help investors understand how companies depend on ecosystems and how their activities may affect biodiversity. However, disclosure should not become the final destination. Reporting that a company faces deforestation risk is useful, but the real test is whether that information changes lending decisions, investment strategies, supply-chain management and corporate behaviour. The objective should be to move from knowing about nature-related risks to actually managing them. (TNFD)

Biodiversity Credits Could Unlock New Capital

Biodiversity credits are among the most interesting developments in the emerging nature finance market. In principle, they could create a financial mechanism through which companies, investors and other organisations support measurable improvements in biodiversity. If credible standards can establish ecological baselines, demonstrate additionality and monitor outcomes over sufficiently long periods, biodiversity credits could help channel private capital toward conservation projects that currently depend heavily on government or philanthropic funding. The Kunming-Montreal Global Biodiversity Framework recognises biodiversity credits and offsets among potential financing mechanisms, while also emphasising the importance of environmental and social safeguards. (Convention on Biological Diversity)

But biodiversity credits also demonstrate why nature cannot simply be treated as another financial asset. Biodiversity is deeply connected to place, species and ecological relationships. Protecting one ecosystem does not necessarily compensate for destroying another, even if both projects can be assigned apparently comparable numerical values. An ancient forest with a unique collection of species cannot necessarily be substituted by planting trees somewhere else. A wetland supporting a particular population of migratory birds cannot simply be made equivalent to protecting a different wetland. If biodiversity credits become a mechanism for companies to purchase permission to continue causing irreversible environmental damage, they could undermine rather than strengthen conservation.

Prevention Should Come Before Compensation

This makes the principle of prevention particularly important. Restoring a damaged ecosystem can be valuable, but preventing its destruction in the first place is often more effective. Some ecosystems contain relationships that have developed over decades or centuries and cannot simply be recreated once they have been lost. A mature forest is more than the number of trees standing on its land. A wetland is more than the area of water it contains. A coral reef is more than a collection of individual organisms. These ecosystems provide interconnected functions that may disappear long before their complete physical destruction becomes visible in financial accounts.

Green finance should therefore be integrated with strong environmental regulation and project screening. Investors should ask whether critical habitats are being avoided, whether less damaging alternatives exist and whether environmental impacts can genuinely be mitigated. Finance should not become a mechanism for making destructive projects appear acceptable simply because they contain a green component. The hierarchy should be clear: avoid environmental damage where possible, minimise unavoidable impacts, restore what has been degraded and only then consider carefully designed compensation mechanisms where they are ecologically appropriate.

Africa Needs a Different Kind of Biodiversity Finance

The issue is particularly important for Africa because biodiversity conservation is inseparable from development. The continent contains globally significant forests, savannas, wetlands, freshwater ecosystems and coastal environments, while many countries simultaneously face major challenges around poverty, food security, energy access, employment and infrastructure. Expecting countries and communities to protect ecosystems without addressing the economic pressures driving land conversion is unlikely to work. If conservation generates few financial benefits while destructive activities provide immediate income, the economic incentives will continue pointing in the wrong direction.

International biodiversity finance therefore needs to consider not only how much money is committed but also how that money reaches the people managing ecosystems. Indigenous Peoples and local communities play critical roles in conserving biodiversity, yet conservation finance can become highly centralised and difficult for local organisations to access. Effective biodiversity finance should provide meaningful participation, transparent decision-making and appropriate economic benefits for communities. The Global Biodiversity Framework recognises the importance of Indigenous Peoples and local communities and calls for biodiversity finance to become more effective, efficient, transparent and accessible. (Convention on Biological Diversity)

The Financial System Has to Start Pricing Nature

At a deeper level, the biodiversity crisis reflects a failure to properly account for the economic value of nature. Companies can depend heavily on freshwater, pollinators, fertile soils, forests and stable ecosystems without paying the full cost of degrading those resources. The consequences may appear later through declining agricultural productivity, water shortages, increased flooding, collapsing fisheries or damaged infrastructure. When those costs are pushed onto governments, communities and future generations, environmentally destructive activities can appear more profitable than they really are.

This is where finance has the potential to become transformative. If banks begin considering nature-related risks when deciding who receives credit, if investors demand credible biodiversity strategies, if insurers price ecological risks more accurately and if governments reform subsidies that encourage environmental destruction, the financial system can begin changing corporate behaviour. Nature would no longer be treated simply as an externality sitting outside the balance sheet. Instead, environmental degradation would increasingly become a financial risk that companies and investors have to manage.

So, Can Green Finance Actually Protect Biodiversity?

Yes, but only if we stop measuring success primarily by how much money has been labelled green. The real measure should be what happens to ecosystems after that money is invested. Are forests remaining intact? Are degraded landscapes recovering? Are wetlands functioning? Are wildlife populations stabilising? Are communities receiving sustainable economic benefits? Are companies changing the practices responsible for environmental damage? Those are the questions that determine whether green finance is actually doing its job.

A credible biodiversity finance system will therefore need several elements working together. It will require more public and private capital for conservation and restoration, but it will also require the redirection of harmful financial flows. It will require better biodiversity data and nature-related disclosure, but also stronger regulation to ensure that disclosure influences financial decisions. It will need innovative instruments such as blended finance and biodiversity credits, but these must operate under credible ecological and social safeguards. Most importantly, it will need to recognise that local communities are not merely recipients of conservation money. They are often central actors in protecting the ecosystems that finance is supposed to save.

Ultimately, a green bond is not a biodiversity outcome. A restored ecosystem is. A sustainability report is not an environmental outcome. A protected habitat is. A biodiversity credit is not proof that nature has benefited. A measurable improvement in ecological health is. Green finance can provide the capital needed to protect biodiversity at a scale that traditional conservation budgets may struggle to achieve, but it cannot substitute for environmental regulation, scientific monitoring, community rights or political commitment.

The future of green finance will therefore be determined by whether it can change the incentives embedded within the wider economy. If billions continue flowing into conservation while trillions support activities that degrade nature, the imbalance will remain. But if financial markets begin rewarding businesses that maintain healthy ecosystems, penalising activities that destroy them and directing capital toward genuinely nature-positive solutions, finance could become a powerful force for biodiversity protection.

The world does not simply need more money for nature. It needs a financial system in which destroying nature becomes harder to finance and protecting it becomes increasingly valuable. That is the real test of green finance.
