When Banks Start Pricing Decarbonisation Risk, Refinancing Becomes a Technical Question

The Language of Credit Has Changed Faster Than Many Owners Realise

Across recent quarters, conversations with financing institutions have begun to sound different. Traditional financial indicators (such as LTV or NOI) are no longer sufficient on their own. They remain necessary, but they no longer complete the picture.

New parameters have moved from “nice-to-have” to standard practice, including:

• alignment with CRREM pathways,
• decarbonisation plans,
• and environmental certifications.

This shift is not only procedural. It is competitive. A difference of just a few basis points in green financing can translate into a real advantage, meaning that environmental performance is no longer only about compliance, it is increasingly a funding lever.

Refinancing Risk in 2026 Is Being Rewritten by Environmental Factors

Environmental risk is now appearing in the refinancing conversation as something measurable and bankable or, in some cases, unfinanceable without a clear plan.

Five factors emerge as particularly decisive for refinancing capacity in 2026.

1) Position Against the Decarbonisation Pathway (CRREM)

Banks are beginning to ask for a specific marker: the “CRREM misalignment year.”

This is the first year in which a building’s emissions intensity exceeds the allocated carbon budget consistent with a 1.5°C scenario.

Reaching that year does not automatically mean the asset loses value. But it does function as a warning signal for transition risk and it is appearing more often inside valuation models.

A key implication is that many portfolios may already be beyond the point they assume they are. In more than half of the buildings audited by the author’s team, that misalignment year has already passed, turning what looks like a future problem into a present underwriting question.

2) Alignment with the EU Taxonomy

The EU Taxonomy is not an abstract policy layer. It has become a direct input into capital decisions.

Investment funds classified under Article 8 or 9 of SFDR must report the share of investments aligned with the Taxonomy. That reporting obligation influences acquisition decisions upstream and refinancing outcomes downstream.

In parallel, banks financing commercial real estate are increasingly rewarding sustainable investments through credit terms, with preferential conditions flowing toward projects meeting ESG criteria. In practice, taxonomy alignment begins to behave like a filter on liquidity: it shapes what can be financed smoothly and what becomes structurally harder to refinance.

3) A New Methodology for Energy Performance Certificates (Already in 2026)

The new EPBD directive changes not only the role of energy certificates, but the methodology used to calculate them.

A critical detail follows: existing certificates will not automatically map onto the new energy classes. Buildings will need to be recalculated under the updated method. An asset that currently holds an “estimated” Class C could, after recalculation, turn out to be Class D.

This creates a real risk for owners who do not re-validate their assets using the new criteria or who optimise certificates for an outcome rather than for genuine reductions in energy demand. The direction is clear: banks will be looking at the new classes, not legacy labels.

4) Mapping Investment Requirements, Not Just Stating Intent

Banks increasingly want a quantified answer to a practical question:

How much investment will be required to keep the building on a pathway consistent with climate goals?

In some cases, achieving specific parameters can become part of financing terms, not simply a best-effort aspiration.

But credible answers require more than a static spreadsheet. Without a dynamic energy model and an intervention-level ROI calculation, it is not possible to respond with confidence. The underwriting conversation moves from general assurances toward measurable, scenario-based planning.

5) Treating ESG as Separate from Technical Condition Is a Costly Error

A methodological mistake is becoming more visible: separating technical due diligence from ESG assessment.

Environmental risks are not “non-technical.” They are technical risks that require integrated work across:

• audits of the buildings envelope, systems, BMS and managemnet,
• energy modelling,
• and regulatory alignment.

The era in which buildings were assessed only through location, lease performance, and technical condition, while ESG sat in a separate report, has ended. The evaluation set is expanding to include parameters that previously belonged mainly to specialist ESG documentation.

Efficiency Becomes the Core Theme: Capital Depends on It

Commercial real estate depends on continuous capital flow. But as underwriting becomes more technical, capital becomes more selective.

Banks are raising requirements far beyond occupancy rates and straightforward valuation logic. ESG, Taxonomy, and energy and climate risk are no longer an attachment to the credit file; they are part of how lenders evaluate whether an asset can generate stable cash flow under changing conditions.

What matters most is not broad declarations of “due diligence,” but operational evidence and forward resilience:

• energy use and emissions intensity,
• the realistic potential to improve efficiency,
• and an investment plan that shows how the asset will perform in coming years, not only under energy price scenarios, but under physical climate threats such as torrential rain or strong winds.

The logic is simple: lenders want confidence that the owner understands risk and can manage it.

Aging Assets Turn This Into a Decade-Defining Challenge

Buildings age continuously. They are constructed under the regulations and technologies of their time both of which shift.

As portfolios mature, owners increasingly face assets that need more than cosmetic upgrades. Serious technical modernisation is becoming common not only for the oldest buildings but also for newer stock. The reference point of the year 2000 is already a quarter-century away.

The challenges are multi-layered:

• evolving energy standards,
• installation quality and system performance,
• occupant comfort,
• and the organisational capacity required to execute large renovation projects.

On top of that sit regulatory pressure and more selective financing conditions. Yet the situation has a clear upside: modernisation is also a pathway to increased asset value and competitiveness, if it is approached as a real investment strategy rather than a reactive compliance exercise.

For many investors, the hardest part is not agreeing that modernisation is needed but ensuring the budget produces outcomes.
