If you have ever wondered how nature supports the global economy or why businesses are now talking about natural capital in the context of ESG and sustainability, the answer is simple. Nature is the foundation of life, health, and business. From forests and freshwater to pollinators and soil, the planet provides the resources and ecosystem services that keep industries running. Yet, much of this natural wealth is invisible in traditional accounting.

This is where the concept of natural capital comes in. Understanding, measuring, and reporting on natural capital is now becoming a strategic priority for companies, investors, and governments. It links environmental stewardship directly to economic resilience and ESG performance.

In this article, we will explore what natural capital is, why it matters for businesses, key environmental focus areas, innovative sustainability models, and how companies can measure, report, and protect natural capital.

What is natural capital?

Natural capital refers to the world’s stock of natural resources and ecosystems that provide essential goods and services for humanity and the economy. This includes:

Forests and soils that store carbon, regulate water cycles, and provide timber and food
Oceans, rivers, and lakes that offer fisheries, transportation routes, and water for industry
Biodiversity and wildlife that pollinate crops, maintain genetic diversity, and regulate ecosystems
Clean air and climate regulation systems that stabilize weather and reduce disaster risks

Think of natural capital as nature’s balance sheet. Just like financial capital or human capital, it is an asset that underpins business activity. When ecosystems are healthy, they generate interest in the form of services. When they are degraded or destroyed, companies face operational, regulatory, and reputational risks.

The Natural Capital Protocol developed by the Capitals Coalition highlights that ignoring natural capital is essentially ignoring future business risk. The World Economic Forum’s Global Risks Report consistently lists biodiversity loss, ecosystem collapse, and natural resource crises among the top threats to global economic stability.

Why is natural capital important for businesses?

Businesses depend on natural capital in more ways than most realize. Consider these examples:

A food company relies on fertile soil, pollinators, and stable rainfall for crop production
A manufacturing company depends on water availability, energy from hydropower, and mineral extraction
A real estate developer depends on natural flood protection from wetlands and forests to reduce disaster risk

When natural capital is degraded, companies face higher costs, supply chain disruptions, and compliance challenges. Investors and regulators are increasingly recognizing that environmental degradation translates into financial risk.

For businesses that adopt ESG strategies, integrating natural capital means:

Reducing exposure to physical and transition risks
Unlocking new opportunities in sustainable products and markets
Enhancing brand trust and investor confidence
Supporting compliance with global disclosure frameworks like CSRD, TCFD, and ISSB

Ignoring natural capital is not only an environmental oversight. It is a strategic blind spot that can impact long-term profitability.

What are the key environmental focus areas of natural capital?

Natural capital is broad, but organizations typically prioritize five environmental focus areas to guide their strategies:

1. Water systems

Water is one of the most visible forms of natural capital. Healthy rivers, lakes, wetlands, and aquifers provide:

Drinking water and sanitation
Irrigation for agriculture
Industrial cooling and processing
Natural flood regulation and water purification

Climate change and industrial overuse are threatening water security worldwide. Companies with high water dependency are now implementing water stewardship programs and using water footprinting tools to protect this critical asset.

2. Land and soil health

Land and soil underpin food security, climate stability, and biodiversity. Healthy soils:

Store carbon and reduce greenhouse gas emissions
Retain water and prevent erosion
Support forests, crops, and grasslands that feed economies

The UN Convention to Combat Desertification (UNCCD) warns that land degradation is costing the global economy trillions annually. Sustainable land management and regenerative agriculture are key pathways to maintain this form of natural capital.

3. Climate stability

Ecosystems such as forests, wetlands, and oceans regulate the climate by capturing and storing carbon. Companies that rely on stable supply chains, shipping routes, and consistent weather patterns have a direct interest in preserving climate stability.

Investing in carbon sequestration projects, renewable energy adoption, and climate resilience protects both natural and business capital.

4. Biodiversity protection

Biodiversity is the web of life that ensures ecosystem stability and productivity. It provides:

Pollination for agriculture
Genetic resources for pharmaceuticals
Healthy fisheries and forestry resources

The IPBES Global Assessment has warned that one million species are at risk of extinction. For businesses, biodiversity loss can lead to raw material shortages, regulatory penalties, and reputational harm.

5. Pollution control

Healthy ecosystems act as natural filters, absorbing and neutralizing pollutants in air, water, and soil. Pollution control as a natural capital focus area includes:

Reducing emissions to prevent smog and acid rain
Protecting wetlands that absorb excess nutrients and industrial runoff
Managing waste to prevent soil and water contamination

When ecosystems can no longer handle pollution naturally, businesses face higher mitigation costs and legal liabilities.

What are the innovative sustainability models for managing natural capital?

To integrate natural capital into corporate strategy, organizations are adopting next-generation sustainability models that move beyond compliance:

The Doughnut Framework
Helps align human development within planetary boundaries, ensuring economic activity does not breach ecological thresholds.
Solutions from Nature
Also known as nature-based solutions, these use ecosystems to address challenges such as flood risk, carbon storage, and coastal protection.
Planetary Thresholds
Defines the environmental limits that must not be exceeded to maintain Earth’s stability, aligned with the Planetary Boundaries Framework.
Circular and Regenerative Models
Focus on eliminating waste and pollution, keeping materials in use, and restoring natural systems.
Ecosystem Contributions and Valuation
Recognizes the economic value of services like pollination, carbon capture, and water filtration.
Multi-Capital Thinking
Encourages decision-making that considers natural, social, human, and financial capital together, leading to balanced long-term strategies.

Companies using these models often see benefits like cost savings, innovation opportunities, and improved ESG ratings.

How can businesses measure and evaluate natural capital?

Measurement and evaluation are critical for credibility and performance improvement. Key approaches include:

Lifecycle Assessment (LCA) to identify environmental impacts across a product’s life
Carbon and water footprinting to quantify resource use and emissions
Biodiversity impact assessment to evaluate project-level ecosystem risks
True Cost Accounting to incorporate hidden environmental costs into financial decisions

Businesses like Unilever, IKEA, and Nestlé have begun integrating natural capital accounting into their operations to anticipate risks and communicate value to stakeholders.

Why assurance, certification, and disclosure are essential?

Implementing natural capital strategies without verification and reporting leaves businesses vulnerable to greenwashing accusations.

Assurance and Certification: Trusted standards like Fairtrade, FSC, ISO 14001, and organic eco-labels build credibility with consumers and investors.
Reporting and Disclosure: Frameworks such as GRI, CDP, TCFD, SASB, and Integrated Reporting enable companies to share their performance in a comparable, investor-ready format.

Transparency transforms sustainability from a claim into a measurable competitive advantage.

Final thoughts on natural capital and ESG

Natural capital is not an abstract environmental concept. It is real, measurable, and directly tied to business resilience. Companies that integrate natural capital into strategy, operations, and reporting are better positioned to:

Reduce supply chain and regulatory risks
Unlock investment from ESG-focused funds
Enhance long-term value creation
Contribute meaningfully to climate and biodiversity goals

In the future economy, protecting nature will not just be good ethics. It will be smart business.
