A physical climate risk assessment used to be something a project commissioned once a regulator or reporting framework required it. That’s changing. Lenders, insurers and investors are increasingly asking for one before a financing decision is made.
The shift matters because it changes what the assessment is for. A study built to satisfy a disclosure requirement sets out to demonstrate that risks have been identified and documented. A study a lender relies on to set financing terms has a narrower, sharper job: showing whether a specific asset, in a specific location, can perform reliably over the life of the financing.
What a physical climate risk assessment evaluates
At its core, the work looks at three things together: the physical hazards a site faces, how exposed the asset is to them, and how vulnerable it is once exposed. Heat stress, flooding, sea-level rise, landslides and extreme weather events are assessed against the asset’s specific location and design life.
That specificity is what makes the assessment useful to a financing decision. A lender needs to know whether this site, with this design and this operating life, is likely to be affected, and what that means for the asset’s performance and value over time.
Disclosure-focused climate work typically starts from the organisation and works outward, covering governance, strategy and reporting metrics as a whole. A financing-driven assessment starts from the physical characteristics of a specific site or set of sites, translating hazard exposure directly into performance, cost and risk terms a lender can act on.
Two of ESC’s recent projects show how differently this plays out depending on the asset.
Energy infrastructure: a single-site, single-purpose risk profile
For a grid-connected energy storage facility, the assessment centres on the physical site itself: flood exposure, heat stress affecting equipment performance, and extreme weather risk to a facility with a fixed location and a long operating life. The output feeds directly into decisions about design resilience and long-term reliability, which matters when the facility is expected to supply power under a long-term arrangement.
A diversified group: risk across an entire network
For a group with multiple subsidiaries and a wider supplier base, the assessment has to account for climate exposure at the company’s own sites and across the operations and locations of its key suppliers. A flood or heatwave at a supplier’s site can disrupt group operations as severely as an event at its own facility. This kind of assessment maps exposure across a network of sites rather than a single location.
Both examples are physical climate risk assessments. The scope, the data and the questions each one answers are shaped entirely by what the asset or organisation actually is.
Why the detail varies by jurisdiction
How this plays out varies across Asia Pacific. Financing standards, the maturity of local climate data and the extent to which lenders formally require this kind of assessment differ from one jurisdiction to the next. The underlying shift holds regardless: physical climate risk is increasingly a factor in the financing decision itself.
Why timing and technical depth both matter
For developers, investors and asset owners, the practical implication is timing. A physical climate risk assessment commissioned after financing terms are largely settled has limited room to influence anything, since the findings arrive once design choices, risk allocation and terms are already fixed. Building it into the financing process early gives the findings somewhere to land.
Getting the timing right also depends on getting the technical scope right from the outset, which is where the assessment’s value comes from.
Build an assessment lenders can act on
Assessing physical climate risk for a financing decision means working across jurisdiction with very different climate data availability, regulatory maturity and lender expectations, often within the same regional portfolio. ESC’s teams operate across Asia Pacific, which means the same assessment methodology can be applied consistently to a single-site asset in one jurisdiction and a multi-supplier industrial network in another, without losing the local regulatory and environmental detail that makes the findings credible to a lender.
That combination, international assessment standards applied with genuine local knowledge of each jurisdiction’s hazards, permitting environment and data landscape, is what makes the output usable by a project team on the ground and an investment committee reviewing it from a distance.
ESC pairs this work with advisory support for clients navigating the financing process, so the assessment is built with the eventual reader, a lender, an investor, an internal risk committee, in mind from the start.
