Ecosystem Services vs Natural Capital

Quick Comparison

What are Ecosystem Services?

Ecosystem services are the benefits people receive from nature, counted as flows over a period of time. The UN's System of Environmental-Economic Accounting (SEEA) defines them as the contributions of ecosystems to benefits used in economic and other human activity, and groups them into three categories: provisioning services such as fish and timber, regulating services such as climate regulation and flood control, and cultural services such as recreation and spiritual reflection.

Services are tied to places. The SEEA program's example is flood control from an upland forest, which benefits only the flood zone downstream. A dependency on a service is really a dependency on a particular ecosystem in a particular location, which is why maps sit at the core of ecosystem accounts.

Counting services takes discipline. Pollination that raises a crop's yield is already reflected in the value of the harvest, so adding the two together overstates the benefit. Good practice records each service once, at the point where it contributes to something people actually use, and states plainly which services were left out.

The business exposure is large. A 2023 European Central Bank analysis found that about 72% of euro area companies, roughly three million firms, are highly dependent on at least one ecosystem service, and that almost 75% of bank loans to euro area companies go to such firms. World Bank modeling published in 2021 estimated that the collapse of a few services, namely wild pollination, food from marine fisheries and timber from native forests, could cut global GDP by $2.7 trillion a year by 2030.

What is Natural Capital?

Natural capital is the stock of natural assets that produces those flows. The definition developed by the Natural Capital Coalition, which the UN's SEEA program cites, describes it as the stock of renewable and non-renewable resources, such as plants, animals, air, water, soils and minerals, that combine to yield a flow of benefits to people. The UN attributes the term to the economist E.F. Schumacher, who used it in his 1973 book Small Is Beautiful.

The asset framing moved into economic policy with the Dasgupta Review, published by HM Treasury in February 2021. The review estimated that between 1992 and 2014, produced capital per person doubled and human capital per person rose about 13%, while the stock of natural capital per person fell by nearly 40%. By its estimate, humanity would need 1.6 Earths to maintain current living standards.

Natural capital is measured through extent, meaning how much of each ecosystem or resource exists, and condition, meaning how healthy it is, with monetary value added where a decision calls for it. For companies, the main method is the Natural Capital Protocol, a decision framework for identifying, measuring and valuing direct and indirect impacts and dependencies on natural capital. The TNFD describes its own approach as building on the Protocol.

Key Differences

1. Stock versus flow. Natural capital is what exists; ecosystem services are what it yields each year. The two can move apart for years: a fishery can land steady catches while the stock behind them shrinks, until the catches fall too.

Take a coastal wetland. Its natural capital is the area of marsh and its condition, from vegetation cover to water quality. Its ecosystem services are the nursery habitat that supports local fish catches, the buffering that shields property from storm surge, the carbon it keeps out of the atmosphere and the recreation it attracts. Drain half the marsh and an asset account shows the loss at once, while a service account may not register it until the next storm arrives.

2. Scope. Natural capital is the broader term. It includes non-living, non-renewable resources such as minerals and fossil fuels, which yield economic benefits but not ecosystem services. Ecosystem services come only from ecosystems, the living systems of land, freshwater and sea.

3. Measurement. Service flows are measured in physical units per period, such as tonnes, cubic meters or damage avoided, and can then be valued. Natural capital is measured through extent and condition, and its monetary value depends on the services it can keep supplying. That link means degradation should register as a loss of asset value before the flows visibly decline.

4. Standards. The UN Statistical Commission adopted SEEA Ecosystem Accounting in March 2021: chapters 1 to 7, the accounting framework, became an international statistical standard, and chapters 8 to 11, on valuing ecosystem services and assets, were adopted as internationally recognized principles and recommendations. Uptake is growing but partial. The UN's 2025 Global Assessment of Environmental-Economic Accounting counted 98 countries compiling SEEA accounts, 58 of them compiling ecosystem or thematic accounts.

5. Valuation is optional. The SEEA program stresses that natural capital accounts can do much of their work in physical terms. South Africa's river accounts, which showed a 10% reduction in river health between 1999 and 2011, are its example of accounts that can guide decisions without monetary valuation. Prices help with specific decisions, such as cost-benefit analysis, but a valuation built for one decision can mislead when reused for another.

6. Who speaks which language. Central banks, lenders and disclosure frameworks mostly talk about services and dependencies, because those map onto operating and credit risk. Statistical offices, finance ministries and land managers mostly talk about natural capital, because their job is managing balances over time. Any strategy that has to persuade both audiences needs to translate between the two.

When to Use Each

Lead with ecosystem services when:

• You are screening operations or supply chains for nature dependencies, for example with the TNFD's LEAP approach.
• You need to show decision-makers what nature does for them in costs avoided, such as flood protection or water treatment.
• You are comparing options like nature-based solutions and grey infrastructure, where the services delivered are the point.

Lead with natural capital when:

• You own or manage land, water rights, forests, fishing access or other natural assets.
• You need to know whether a resource base can support the business for decades, not just this year.
• You are building accounts that track change over time, for a site, a company or a country.
• You are a government, utility or landowner planning long-lived investments in watersheds, forests or coastlines, where the question is what the asset will be worth to the next generation.

Use both when:

• You are setting nature targets or disclosing nature-related risks, which requires the condition of the asset and the services it supplies.
• You are making the case for a restoration investment: the capital you rebuild and the flows it brings back.

Council Fire's Recommendation

Start with the stock. Most corporate nature work begins with a list of services the business depends on, which is useful but incomplete, because flows can hold steady while the asset beneath them degrades. We recommend pairing each material dependency with the natural asset that supplies it and a condition indicator for that asset, measured in physical terms first. Monetary valuation earns its place when a specific decision needs it, such as a capital allocation or a restoration business case, rather than as a first step.

Council Fire treats this as a strategy and stakeholder engagement problem as much as a measurement one. The people who manage watersheds, fisheries and farmland often hold the best condition data, and involving them makes an assessment both more accurate and more credible. When a program needs that data kept current and shared across teams, we build the decision tools and dashboards to do it, through Council Fire Labs.
