As climate change accelerates, it is reshaping not just our environment but also the very foundation of global economic systems. For financial institutions, investors, and corporate risk managers, understanding and integrating climate risks into decision-making is no longer optional—it is essential.

Integrating Climate Models into Financial Decision-Making As climate change accelerates, it is reshaping not just our environment but also the very foundation of global economic systems. For financial institutions, investors, and corporate risk managers, understanding and integrating climate risks into decision-making is no longer optional—it is essential. This is where climate modelling plays a pivotal role, offering tools to predict and quantify how climate-related factors impact financial performance, asset valuations, and long-term investment strategies.

Why Climate Modelling Matters for Finance

1. Climate Change as a Financial Risk:

-Physical risks such as floods, wildfires, and hurricanes are causing direct damage to infrastructure, disrupting supply chains, and leading to increased insurance claims.

-Transition risks arise from policy changes, shifting market preferences, and technological disruptions as the world moves toward a low-carbon economy.

-Liability risks stem from legal actions against companies for their role in contributing to climate change or failing to disclose related risks.

2. Regulatory Requirements for Climate Risk Disclosure:

-Financial regulators globally are mandating the inclusion of climate risks in corporate reporting and financial decision-making. Frameworks such as the Task Force on Climate-related Financial Disclosures (TCFD) and the EU’s Corporate Sustainability Reporting Directive (CSRD) require organizations to assess and disclose how climate risks affect their operations and financial health.

3. The Financial Implications of Climate Inaction:

-Failing to account for climate risks can lead to asset devaluation, loan defaults, and portfolio underperformance. According to the Network for Greening the Financial System (NGFS), ignoring climate risks could result in global GDP losses of up to 18% by 2050 under worst-case scenarios.

Types of Climate Models Used in Finance

1. Physical Climate Models:

-These models simulate the impact of physical climate events on assets and infrastructure. They help predict how events like sea-level rise, extreme weather, and temperature changes could affect specific geographic regions and sectors.

Applications in Finance: -Real estate investment trusts (REITs) use physical climate models to assess flood risks to properties.

-Insurers leverage these models to set premiums based on projected wildfire or hurricane risks.

2. Economic-Climate Models (Integrated Assessment Models -IAMs):

-IAMs combine climate science with economic theory to assess the costs and benefits of climate mitigation strategies. These models help policymakers and investors understand the economic impacts of different climate pathways.

Applications in Finance: -Sovereign wealth funds use IAMs to model the long-term economic impacts of carbon pricing on national economies.

-Central banks employ IAMs in climate stress testing for the financial sector.

3. Transition Risk Models:

-These models focus on the financial implications of the transition to a low-carbon economy, including the risks posed by regulatory changes, carbon pricing, and technological disruption.

Applications in Finance: -Asset managers use transition risk models to evaluate the potential for stranded assets in sectors like oil and gas, coal, and automotive.

-Banks apply these models to assess how carbon taxes might affect the creditworthiness of borrowers in carbon-intensive industries.

Climate Stress Testing in Financial Institutions

1. What is Climate Stress Testing?

-Climate stress testing involves simulating how extreme climate scenarios—such as a 2°C warming pathway or a rapid transition to net-zero emissions—would impact a financial institution’s balance sheet, loan portfolio, and investment holdings.

2. Key Examples of Climate Stress Testing Initiatives:

-European Central Bank (ECB) Climate Stress Test: In 2022, the ECB conducted its first climate stress test, covering 104 banks with combined assets of over €24 trillion. The results revealed that 60% of banks were unprepared for climate risks, prompting stricter capital reserve requirements and enhanced risk management protocols.

-Bank of England’s Climate Biennial Exploratory Scenario (CBES): The CBES assessed how UK banks and insurers would respond to various climate- related shocks, from physical risks like flooding to transition risks such as carbon pricing. The findings indicated potential losses of £110 billion by 2050 under delayed transition scenarios.

-US Federal Reserve Pilot Climate Risk Analysis (2023-2024): The Fed launched a pilot program with six major banks, including JPMorgan Chase and Goldman Sachs, to analyze the financial impacts of climate change on mortgage defaults, credit risk, and loan portfolios.

Tools and Technologies Driving Climate Modelling in Finance

1. AI and Machine Learning in Climate Risk Assessment:

-Artificial intelligence (AI) and machine learning are revolutionizing how climate data is processed and analyzed. AI can analyze satellite imagery, weather data, and financial reports to identify climate risks and opportunities in real-time.

Key Applications: -JPMorgan Chase is using AI to integrate climate risk data into loan underwriting and investment strategies.

-Moody’s and S&P Global have incorporated AI-driven climate risk metrics into corporate credit ratings.

2. Satellite Imagery and Remote Sensing for Asset-Level Risk Analysis:

-Satellite technology enables financial institutions to monitor physical risks like deforestation, flooding, and urban heat islands with high accuracy. This data helps assess the vulnerability of specific assets to climate change.

Key Applications: -Reinsurance companies use satellite data to evaluate exposure to natural disasters.

-Real estate investors rely on remote sensing to assess flood risk in property portfolios.

3. Scenario Analysis Tools and Platforms:

-Platforms like Climate Risk Analytics and Carbon Delta offer scenario-based modelling tools that help investors and financial institutions align their portfolios with Paris Agreement goals.

Key Applications: -BlackRock’s Aladdin platform integrates climate risk scenarios to assess portfolio resilience under different global warming pathways.

-MSCI ESG Research provides scenario analysis tools for evaluating how companies and sectors would perform under varying climate policy environments.
