Why professional risk is becoming central to natural capital markets

As natural capital insurance markets mature and private funding flows into nature regeneration projects the risks facing organisations operating within them are becoming clearer, more contractual, and incorporating financial liabilities at scales not seen before. Whether an organisation is directly involved in nature regeneration, delivering natural capital outcomes, or acting as an advisor, aggregator or intermediary on nature regeneration projects, professional risk now sits at the heart of value creation.

A Professional Indemnity (PI) insurance policy exists to protect organisations against claims arising from the professional services they (and with the right policy, their sub-contractors) provide in the creation, management and financing of natural capital.

Simply, if an organisation is involved in natural capital projects such as biodiversity net gain or carbon credits, or wider nature investments, PI insurance is no longer optional infrastructure but rather it is the crucial foundation of nature insurance for anyone operating or looking to operate with private funding.

It can however be expensive, misallocated, or placed poorly, and can be burdensome without proper understanding and review. We have created our own bespoke Nature Professional Indemnity insurance for those operating in the nature regeneration and environmental space specifically to address these issues.

The professional risk behind creating natural capital

Although natural capital outcomes are physical in nature - habitats restored, emissions sequestered, ecosystems enhanced - the risks that arise during delivery are predominantly professional rather than operational away from large scale physical losses.

Examples of how claims could arise:

Technical advice, ecological assessments, or calculations
Project design or methodology selection
Regulatory interpretation and compliance support
Baseline data or modelling assumptions
Long‑term management or delivery plans
Reliance placed on reports, certifications or statements

Because biodiversity units, carbon credits, and ecosystem service outcomes are sold, financed, or relied upon by third parties any professional error can result in significant financial loss, even where no physical damage has occurred.

This is why natural capital insurance, in the form of PI, is so critical.

What PI insurance actually protects

A well‑constructed PI policy for natural capital projects and nature regeneration protects organisations and individuals where claims allege that professional services failed to meet the required standard.

This typically includes protection against claims relating to:

Errors or omissions in professional advice
Inaccurate or misleading reports or assessments
Design or modelling failures
Financial loss suffered by clients, investors or counterparties

Crucially, comprehensive PI insurance covers defence costs, often from the moment a claim or allegation is made - regardless of whether that claim ultimately succeeds.

In markets such as biodiversity net gain insurance and carbon credit insurance, where multiple parties rely on professional judgement across long project lifecycles, with multiple layers of private buyers and financers who are due to lose significant funds in the case of the above failures, this protection is essential.

Protection across the natural capital value chain

Project developers and delivery entities

Organisations directly delivering nature restoration, habitat banks, or other natural capital projects carry professional exposure far more than they possibly realise, particularly where units are sold or pre‑committed. Not only are they liable for the losses they directly impact, but also for any failures of entities or individuals they have sub-contracted to do the work. Nature regeneration insurance via PI cover protects against claims linked to professional failures rather than physical loss itself. Our cover in particular explicitly expands to ensure that activities of sub-contractors are included.

Advisors and consultants

Ecologists, planners, engineers, accountants and specialist natural capital advisors often sit at the core of risk creation. Their advice underpins investment, compliance and planning decisions. PI which should be structured alongside environmental performance insurance such as our Natural Capital cover, protects against claims arising from reliance on that advice.

Aggregators and portfolio managers

Aggregation increases, rather than dilutes, professional exposure. PI protects against claims arising from portfolio construction, due diligence, oversight, reporting or allocation errors, all of which are key to credible natural capital risk transfer.

Brokers and intermediaries

Entities facilitating transactions, introductions, expert translation, or structuring activity face exposure where information is incomplete, misunderstood or misrepresented. PI is essential for sustainable intermediation, particularly when these entities are operating outside of regulatory oversight.

What our market leading PI cover does above and beyond for our clients

We have worked with a leading environmental insurer to create a bespoke product exclusively for our clients. We will always ensure that a review of the relevance of this cover is carried out, however, we are confident that our solution is feasible for the majority of nature professionals.

Civil liability rather than third party loss only

Standard PI insurance responds to claims arising from professional services, advice, designs, assessments and reports that cause financial loss to a third party.

Civil liability, more broadly, incorporates the above and refers to any non‑criminal legal liability owed to another party - including contractual, negligence or statutory claims.

Cover for sub-contracting activities

As subcontractors play a crucial role in the implementation and maintenance of nature projects – particularly when SPVs are being set up for location specific activity – our PI cover ensures that those activities are included as standard.

It is important that for matching of liability all sub-contractors should be required to carry PI cover as well.

Additional Cover for Environmental Liability

As a true market leader in Nature Regeneration, we have incorporated Environmental Liability into our PI insurance as standard.

What this covers:

Sudden and gradual pollution or environmental/biodiversity damage, including contamination of land, water, or habitats, and the associated clean‑up, remediation, and third‑party damage costs arising from insured operations
Regulatory and third‑party claims linked to environmental harm, including costs imposed by regulators, emergency mitigation expenses, and legal defence costs where environmental damage has occurred

Why PI is essential market infrastructure

As nature investments become institutional and contractual, the expectations placed on nature professionals now mirror those in established asset classes such as infrastructure, construction, and finance.

PI insurance:

Creates confidence between counterparties
Supports investor participation
Protects firms from balance‑sheet‑threatening claims
Secures sub-contracted activities and their non-delivery
Enables growth without absorbing disproportionate professional risk
Underpins long‑term market credibility

Without appropriate PI cover, professional failure becomes commercially unmanageable - even where intentions and environmental outcomes are positive.

A professional market requires professional protection

If natural capital and nature regeneration projects are to function as durable, investable asset classes then the organisations designing, enabling, and managing them must operate within robust risk frameworks.

Nature insurance, and particularly PI insurance, is not an optional add‑on.

It is part of the core infrastructure that allows the market to scale with confidence, accountability and trust.
