Climate risk assessment is the process of identifying, analysing and evaluating how climate change may affect an organisation’s operations, assets and long-term strategy. It helps businesses understand potential physical, transition and regulatory risks linked to climate change so they can develop effective resilience and adaptation strategies.
Over the last few decades, the world has increasingly recognised the devastating impact of climate change on the operational, financial and strategic well-being of organisations worldwide. According to the Intergovernmental Panel on Climate Change (IPCC), extreme weather events such as droughts, storms and heatwaves are becoming more frequent and intense due to rising global temperatures. These changes can affect infrastructure, productivity, ecosystems and public health across multiple sectors. For businesses preparing for climate change, the first step in understanding associated risks is to answer the question: what is climate risk assessment? Answering this question is the first step in identifying potential climate threats, evaluating vulnerabilities and developing effective mitigation strategies.
Climate risk assessment refers to a structured process used to identify, analyse and evaluate the potential impacts of climate change on an organisation’s operations, assets and strategic objectives. These risks are not limited to environmental hazards alone, but also include economic, regulatory and reputational pressures that emerge as our society transitions toward a low-carbon, nature-positive future. Within a structured climate risk assessment, risks are typically grouped into three core categories.
These relate to the direct impacts of climate change on infrastructure, operations and supply chains. Physical risks are becoming increasingly relevant for organisations whose assets or suppliers are exposed to changing weather patterns or climate extremes. Common examples include:
These hazards can affect operational continuity, increase maintenance costs, and create long-term investment risks if facilities are located in climate-vulnerable areas. Assessing these exposures is therefore a central part of understanding what climate risk assessment involves.
Transition risks arise from the global shift towards a low-carbon economy. As governments introduce climate policies and industries decarbonise, organisations may face financial and operational pressures associated with adapting to these changes. Examples of transition risks include:
For many businesses, particularly those operating in emissions-intensive sectors, these transition pressures can influence investment decisions, operational strategy and long-term competitiveness.
In addition to physical and transition risks, organisations must also consider reputational and liability risks associated with climate change. Stakeholders increasingly expect businesses to demonstrate transparency and proactive climate management. These risks may arise from:
As climate disclosure frameworks expand and public scrutiny increases, reputational risks can directly influence brand value, investor confidence and regulatory compliance.
Understanding these interconnected risks helps organisations build a comprehensive climate resilience strategy that supports long-term corporate climate resilience.
The simple answer is: Yes. While organisations may vary in their approach to understanding risks from climate change, in practice, most climate risk assessments follow a structured methodology used by governments, research organisations and sustainability practitioners.
Typical steps include:
This structured approach helps organisations answer the question: what is climate risk assessment in practical terms by translating climate data into actionable business insights.
Conducting a climate risk assessment is only the first step. The ultimate goal is to translate risk insights into practical strategies that strengthen climate resilience across operations and supply chains. Structured planning enables organisations to develop a comprehensive climate resilience plan that reduces vulnerabilities and prepares businesses for future climate conditions.
Examples of resilience actions may include:
Integrating these actions into organisational strategy helps businesses develop a robust climate resilience plan that supports long-term operational stability. Organisations are beginning to plan ahead by embedding climate resilience into enterprise risk management and sustainability planning, ensuring climate risks are considered alongside financial and operational risks.
In answering the question, what is climate risk assessment, organisations gain a clearer understanding of how climate change can affect their operations, infrastructure and long-term strategy. A structured climate risk assessment enables businesses to identify potential hazards, understand site vulnerabilities and prioritise the risks that pose the greatest threat to operational continuity and financial performance. Developing a proactive approach to climate impact helps businesses strengthen climate resilience, develop an effective climate resilience plan and build long-term corporate climate resilience across their operations and supply chains. This is what Tunley Environmental’s climate risk assessment service is designed to deliver, providing organisations with a structured approach to identifying climate-related hazards, assessing operational vulnerabilities and developing practical strategies.
