Sustainability risk – A governance tool for understanding exposure, distinguishing influence and making better decisions in an increasingly uncertain world
As Jersey’s Business Sustainability Risk requirements come into force next year, many firms are focused on the practical question of compliance: identifying risks, assessing materiality and strengthening governance.
These are important requirements. However, there is a more fundamental question that deserves attention:
Why are regulators asking firms to do this in the first place?
The answer is often misunderstood.
Climate risk regulation is not primarily about asking trustees, directors and financial institutions to solve climate change. Nor is it based on the assumption that individual firms can control global emissions trajectories, energy systems or land-use practices.
Instead, regulators are responding to a different concern.
Climate change represents a source of risk that is long-term, uncertain and systemic. It has the potential to affect multiple sectors, geographies and asset classes simultaneously. If these risks are not understood and governed appropriately, they can accumulate across institutions and markets, creating vulnerabilities within the financial system.
The objective of climate risk regulation is therefore straightforward: to improve understanding of climate-related exposures before they become sources of financial instability.
At its core, climate risk assessment is an exercise in understanding exposure.
This distinction is important.
Recent research from Columbia University’s Center on Sustainable Investment highlights that climate change begins as a physical hazard, which may create economic impacts that ultimately translate into financial risks. While these concepts are connected, they are not the same.
There are two structural realities that make climate risk assessment particularly tricky.
First > Climate risk does not move directly from hazard to financial loss.
Between a climate event and a financial outcome sit businesses, markets, insurers, governments and economic systems that can either amplify or absorb impacts. Understanding these transmission pathways is often more valuable than attempting to predict the precise financial outcome itself.
This is why a core output of any climate risk assessment we perform is the mapping of these transmission pathways. They are often more valuable than the risk rating itself because they help decision-makers understand how climate-related developments could ultimately affect their organisation, investments or beneficiaries.
Second > Understanding a financial risk does not necessarily create the ability to influence the underlying climate hazard that drives it.
For trustees and investors, a climate risk assessment may identify exposure to physical climate impacts, carbon-intensive sectors or transition-related disruption. Understanding those exposures is valuable. However, identifying them does not mean the organisation can directly influence global emissions, energy policy or technological change.
This is where many climate risk discussions become confused.
The most valuable outcome of a climate risk assessment is not the identification of risks. It is understanding how those risks could translate into financial outcomes and where an organisation has the ability to influence those outcomes.
From a governance perspective, climate-related risks generally fall into three categories:
- Risks we can influence directly through investment decisions, manager selection, stewardship priorities or operational actions.
- Risks we can influence indirectly through engagement, collaboration and market participation.
- Risks we cannot meaningfully control but must understand, monitor and govern appropriately.
This distinction matters because good governance is not about creating an illusion of control. It is about making informed decisions within the sphere of influence available to us.
For Jersey trustees, boards and financial institutions, this may be the most important lesson from the new regulatory requirements.
The purpose of climate risk assessment is not to predict the future with precision. It is not to make individual firms responsible for solving climate change. It is to help decision-makers understand where vulnerabilities exist, where influence can be exercised and how resilience can be strengthened.
Viewed through this lens, climate risk assessment becomes more than a compliance exercise. It becomes a governance tool. A tool for strengthening resilience, improving decision-making and supporting the long-term stability of both individual organisations and the financial system as a whole.
