Dame Alison Rose on What Real Estate Investors Owe the Climate Transition

Buildings account for a substantial share of global energy consumption, and the overwhelming majority of the buildings that will exist in 2050 are already standing. That single fact shapes the obligation facing real estate investors, and it makes their position different from that of investors in most other sectors. Dame Alison Rose, whose career in banking gave her a long view of how property lending behaves across cycles, has argued that the sector’s duty is less about what it builds next and more about what it does with what it already owns.
The Retrofit Problem
New construction attracts the attention. A high-performance building is photogenic and marketable at a premium. Retrofitting a 1970s office block is none of those things. It is disruptive, difficult to finance against uncertain returns, and frequently constrained by tenants who cannot vacate.
Yet the arithmetic is unforgiving. A sector that decarbonises only its new supply will decarbonise a small fraction of its footprint, since new supply is a low single-digit percentage of stock in any given year. Dame Alison Rose has framed the retrofit gap as the defining obligation of real estate capital, precisely because it is the part nobody has a commercial incentive to volunteer for.
Why the Incentives Point the Wrong Way
The structural obstacle is that the party who pays for a retrofit is often not the party who benefits. A landlord funds the works. A tenant enjoys the lower energy bills. Under most lease structures, the landlord recovers little of that saving, which turns an environmentally sensible investment into a commercially poor one.
This is not a failure of will. It is a failure of contract design, and Rose has been consistent that describing it as a values problem obscures the actual fix. Green lease structures that share the benefit exist and remain a minority of the market.
The Stranding Risk Nobody Prices
A building that cannot meet tightening efficiency regulation becomes unlettable before it becomes unusable. In several jurisdictions, minimum energy standards already prevent the leasing of the worst-performing stock, and those thresholds ratchet upward on published timetables.
An investor holding such an asset faces a value cliff at a known future date. Dame Alison Rose has noted that valuation practice has been slow to reflect this, partly because the comparable transactions used to price property are backward-looking by construction. A market that prices from recent sales will keep pricing the risk at zero until a sale finally demonstrates otherwise.
What Lenders Can Change
Real estate is a leveraged asset class, which gives lenders unusual influence. A bank that adjusts loan-to-value assumptions for buildings on a stranding path changes borrower behaviour immediately, in a way that no voluntary framework achieves.
Drawing on how property exposure was assessed inside NatWest Group, Rose has argued that this is ordinary credit work rather than a sustainability initiative. A lender secured against an asset that may be unlettable in eight years has a straightforward prudential interest in knowing that, independent of any view about climate policy.
The Data That Does Not Exist
Assessing a building’s transition risk requires operational energy data, which for most commercial property is held by tenants under meters the landlord cannot read. Owners frequently do not know how their own buildings actually perform, relying instead on modelled ratings that correlate poorly with measured consumption.
Closing that gap is unglamorous work involving submetering and lease clauses that grant data access. It is also the precondition for everything else, since a portfolio cannot be prioritised for retrofit without knowing which assets are worst.
What Investors Actually Owe
Dame Alison Rose, now a senior partner at Charterhouse, has resisted framing this as a moral debt, which she regards as an argument that loses whenever budgets tighten. Her formulation is closer to a fiduciary one. An investor holding a long-duration physical asset in a sector facing known regulatory tightening has an obligation to understand and price that exposure, and failing to do so is a competence failure rather than an ethical lapse.
That framing has practical consequences. A duty grounded in fiduciary care survives a recession, gets reported to an investment committee, and shows up in valuation models. A duty grounded in conscience gets deferred to a better year.
The Longer Horizon
Property investors operate on timescales that make the transition unavoidable rather than optional. A twenty-five-year hold spans multiple regulatory regimes and at least one significant shift in what tenants will accept. The sector’s advantage is that its time horizon already matches the problem, which is more than most asset classes can claim.
