NVaR - Earth Capital Nexus

From water to forests, soils and biodiversity, natural systems underpin economic output, supply chains and financial stability. Yet these dependencies are rarely translated into measurable financial risk within financial or macroeconomic frameworks.

Nature Value-at-Risk (NVaR) is an analytical methodology developed by Earth Capital Nexus to estimate the potential economic and financial losses associated with ecosystem degradation.

Drawing on established Value-at-Risk principles in finance, NVaR links biophysical shocks to sectoral output, supply chains and financial exposure, enabling integration into risk management, supervision and macroeconomic planning. Traditional assessments identify where economic activity depends on ecosystem services. NVaR goes further by translating those dependencies into measurable financial risk under defined degradation scenarios.

What NVaR measures and how it supports decision-makers

NVaR estimates the share of economic output and financial value-at-risk under defined ecosystem degradation scenarios. It combines three core components:

Hazard: the likelihood and severity of disruption to ecosystem services through factors such as drought, water scarcity, flood protection loss and biodiversity decline.
Exposure: the economic value of sectors, assets and supply chains dependent on ecosystem services.
Vulnerability: the sensitivity of output, revenues and financial performance to ecosystem loss.

Together, these elements generate a forward-looking monetary risk metric that can be aggregated across sectors, geographies and time horizons.

Applied at the national or regional scale, NVaR reveals that nature-related shocks can place a substantial share of economic activity at risk – including through cross-border transmission via trade and financial linkages.

By embedding ecosystem risk within economic and financial metrics, NVaR enables decision-makers to:

Improve risk pricing and capital allocation
Strengthen resilience within corporate strategy and sovereign planning
Integrate nature into financial architecture and macroeconomic analysis
Consider nature as economic infrastructure by making its degradation financially visible.

This matters because rather than a peripheral environmental concern, nature-related risk is: a source of credit and portfolio exposure for financial institutions; a form of macro-critical vulnerability for sovereign balance sheets; a supply chain dependency for firms; and a financial stability consideration for central banks and regulators.
