ESG perspective: What is natural capital and why do we care?

Adrienn Sarandi, global Head of ESG Solutions & Strategic Initiatives, discusses why integrating natural capital related risks and opportunities can enable investors to recognise systemic risks early and allocate capital to solutions that will underpin a more sustainable economy.

Key takeaways:

  • Nature provides trillions of dollars in economic value and its degradation poses systemic risk for governments, companies, and investors.
  • The scale of biodiversity loss and ecosystem degradation is alarming and urgent action is needed to preserve vulnerable species and ecosystems that underpin our economy, our society and make human life possible.
  • The imminent release of the TNFD framework should improve biodiversity-related disclosures and help investors evaluate biodiversity-related dependencies and impacts.

What is natural capital

Natural capital is the world’s collective stock of renewable and non-renewable natural resources, specifically, geology, atmosphere, sunlight, soil, air, water, and living organisms. From the air we breathe, to the food we eat, natural capital assets provide us with invaluable goods and services free of charge.

Natural capital includes all living organisms that we call ‘biodiversity’. As we explored in our 2022 Biodiversity – the other systemic crisis primer, biodiversity can be defined as the volume, variety, and variability of life on Earth, as well as how different species interact with each other and the physical world around them. Biodiversity enables the flow of ‘ecosystem services’ that we receive and depend upon.  These ecosystem services make life possible.

Drivers and impacts of nature loss

The scale and speed of the deterioration of the world’s land and sea ecosystems is striking. Estimates suggest around 70% of animal species have disappeared since 1970 and one million species are currently at risk of extinction*. Meanwhile, humans, and domesticated livestock (mainly cows and pigs) now account for 96% of all mammal biomass.

The situation is equally concerning in the Earth’s waters. We dump eight million tonnes of plastic into the sea every year, around one garbage truck per minute. Coral reefs and marine ecosystems are becoming barren wastelands because of pollution and rising sea temperatures. The overexploitation of fish and other species for food has also led to their sharp decline.

As a result, the ‘sixth mass extinction’ is underway, with five key drivers linked to human activity.

Like climate change, biodiversity loss represents both a systemic risk to entire economies and a risk to individual companies. Climate change and nature degradation are also deeply interconnected and mutually reinforcing. For example, deforestation results in habitat and biodiversity loss, and reduction of carbon sequestration capacity, worsening the climate crisis. Climate change reduces biodiversity through increased incidence and severity of weather extremes, which degrades habitats, and can result in desertification and ocean acidification. Marine ecosystems impacted by species loss absorb less carbon. Both challenges operate around tipping points that, once passed, lead to unpredictable and potentially devastating outcomes.

Why do we care?

Nature underpins our economy, society and makes human life possible. Over half the world’s total gross domestic product (GDP), US$44 trillion, is moderately or highly dependent on nature and its services, meaning ecosystem degradation could materially jeopardise the functioning of society and the global economy. Despite this, there has been an underappreciation of natural capital, compared to produced and human capital. For example, ecosystem services have historically been excluded from national balance sheets. Hence, we need global collaboration to start accounting for nature degradation.

To illustrate the challenge, Earth’s ‘Overshoot Day’ took place on 2 August 2023. This marks the date when humanity’s demand for ecological resources and services exceeds what Earth can regenerate in a given year. In the remaining 151 days of 2023, we are operating in overshoot. Estimates suggest we need 1.7 Earths to maintain humanity’s current way of life. Moreover, the Overshoot Day has been getting progressively earlier since the 1970s and we are depleting resources at an ever accelerating and unsustainable rate.

Healthy societal and environmental systems are critical to the functioning of economic systems. The gap between humanity’s demands on nature and nature’s ability to supply is widening and threatens continued provision of the critical ecosystem services underpinning key economic sectors, as shown in Figure 3.

Janus Henderson’s view and approach

At Janus Henderson, we view the scale and severity of the damage to nature and its many knock-on impacts as representing significant financially material long-term risks for certain sectors and issuers. Analysis shows these risks are concentrated in sectors with the greatest dependencies on nature, including agriculture, forestry, and fishing; water and heat utilities, food and beverage; mining; transport; and construction.

The risks are multi-dimensional, and some companies will have outsized exposure to the physical impacts of nature degradation, and others to transition risks due to policy and regulatory risks. Litigation risks, loss of reputation, brand damage, and shifting consumer demand also present meaningful risks, but also potential opportunities for companies to gain market share.

By integrating financially material risks associated with the decline of natural capital, investors have the opportunity to build more resilient portfolios, and also contribute to nature’s restoration by engaging with companies on reducing their harmful impact on biodiversity and formulating innovative solutions. They will need to be enabled by nature-positive government policies and a practical framework that enables implementation.

The quality and depth of data and disclosures on nature and biodiversity are still nascent, largely because mapping out dependencies and impacts is a complex and challenging undertaking for corporates, investors, and governments alike. However, with the TNFD framework we hope corporate disclosure will markedly improve in coming years and financial market participants can advance their journey faster to map out nature-related dependencies and impacts through their investments.

Forging a path ahead

Despite the stark statistics, there is hope. Nature is remarkably resilient and ecosystems and wildlife can regenerate, even in areas where one would think impossible. However, this is possible only if we respect planetary boundaries** (the limits within which humanity can develop and thrive) and don’t push ecosystems to the point of no return.

As biodiversity loss is one of the most critical planetary boundaries that we have already exceeded, time is of the essence. We must start valuing natural capital appropriately in order to transition to a more sustainable economic model which recognises nature’s importance to the economy and our well-being. This will require systems change***.

We are continually evolving our thoughtful, practical and research driven approach to identify risks and opportunities associated with companies’ interactions with nature through their operations and supply chains. We use third-party biodiversity-related data where available, and ongoing engagement as a key tool to understand our portfolio companies’ nature-related dependencies and impacts.

In recent years, we have engaged on biodiversity-related issues such as deforestation (cattle, palm oil, soy) and plastic waste as part of our long-term thematic engagement programmes. These engagements have been driven by our investment teams, with the support and collaboration from the central Responsibility team. We are also a member of the TNFD Forum and the recently launched PRI Nature Reference Group and we are becoming a founding member of Nature Action 100 in September 2023, where we will be seeking to engage with select companies on their preparedness to mitigate nature-related risks.

Important information

Environmental, Social and Governance (ESG) or sustainable investing considers factors beyond traditional financial analysis. This may limit available investments and cause performance and exposures to differ from, and potentially be more concentrated in certain areas than, the broader market.
