When the hospitality industry talks about sustainability, the conversation is almost always about energy. Solar panels on the roof, heat pumps, smart thermostats, water-saving showerheads; the tools of operational carbon reduction are well understood, widely adopted, and increasingly table stakes for any operator with ESG ambitions. These interventions matter, and the best in the industry have made genuine progress.
But there is one area of colossal and largely unaddressed impact, and it is hiding in plain sight: the interiors.
The carbon you cannot see
Every material in a hotel room carries embodied carbon; the emissions generated by extracting the raw materials, manufacturing the product, transporting it to site, and installing it. The steel in the desk. The timber in the wardrobe. The foam in the seating. The carpet, the curtains, the ceramic tiles, the plasterboard, the paint. Every element has a carbon cost that was incurred before the guest ever walked through the door.
In a conventional hotel fitout, these emissions are significant. But they become truly alarming when you factor in the industry’s refurbishment cycle. Most hotels refresh their interiors every seven to ten years; not as a surprise, but as a known, predictable commercial reality driven by brand refresh, technical upgrades, new investment, and wear and tear. In many cases, everything comes out and everything goes in new. The embodied carbon from the original fitout is written off. A new set of emissions is generated. And the cycle repeats.
The numbers tell the story clearly. In a new build, fit-out (interiors) accounts for approximately 29% of a building’s total embodied carbon. By the first refurbishment cycle at around year seven, that share has grown to 44%. By the second cycle at year fourteen it reaches 55%, and by year twenty-one it accounts for 57% of all embodied carbon; more than structure and MEP combined. (Source: LETI, RICS & Carbon Leadership Forum.) This is the compound effect of designing for replacement rather than continuity. Every cycle, the interiors’ share of the building’s total carbon liability grows because the structure endures, MEP is often designed for continual upgrades and the fit-out isn’t.
Construction as a whole accounts for approximately 40% of global carbon emissions. Within that figure, the embodied carbon from interior fitouts and refurbishments is substantial, and in hospitality, where the churn of materials is faster than in almost any other building type, it is particularly acute.
Why the industry is looking in the wrong place
The focus on operational carbon is understandable. It accounts for approximately two thirds of the 40% I previously mentioned and it is measurable, it is visible, and the interventions are well established. A hotel can install solar panels and report how much energy is being generated. The business can calculate energy consumption on a room by room basis and demonstrate the savings. These are tangible, communicable actions that satisfy ESG reporting requirements and appeal to increasingly environmentally conscious guests.
Embodied carbon from interiors is harder to measure, less visible, and the interventions are less familiar. There is no equivalent of a solar panel for reducing the carbon embedded in a wardrobe. The solution requires a fundamentally different approach to design; not bolting on a technology, but rethinking how materials are specified, how products are constructed, and how spaces are designed for their entire lifecycle rather than just their opening day.
This is precisely why the industry is looking in the wrong place. The operational carbon interventions are important, but they are increasingly well understood and widely adopted. The marginal gains from further operational improvements are diminishing. Meanwhile, the embodied carbon from interior fitouts and refurbishments remains largely a blind spot in an industry that prides itself on its sustainability credentials.
There is also a growing financial dimension to this blind spot. Embodied carbon reporting is tightening. Assets with high refurbishment carbon liability are beginning to face lender scrutiny and valuation pressure. Designing for disassembly and understanding commercial lifecycles is no longer just an ethical position, it is becoming a balance sheet consideration.
What the numbers look like when you do it differently
On our London financial district hotel project, we achieved a 75% reduction in embodied carbon compared to a typical hotel fitout with complete replacement. This was not achieved through carbon offsetting or purchasing credits. It was the direct result of keeping materials in use.
By designing for disassembly; using mechanical fixings rather than adhesives, specifying separable materials, creating modular furniture systems, we enabled the hotel to refurbish without demolishing. Steel frames were powder-coated in new colours rather than scrapped. Timber shelving was refinished to factory standard rather than replaced. Drawer units were reconfigured rather than discarded. The materials we had specified seven years earlier; quality timbers, durable metals, separable components, continued to perform, maintaining their utility and their value.
The carbon savings were dramatic because the approach addressed the root cause of the problem: the assumption that refurbishment means replacement. When you design for refurbishment rather than replacement, you avoid the carbon emissions from manufacturing new furniture, the energy required to extract and process virgin materials, and the emissions from transporting new products from factory to site.
And here is the critical point: the same design decisions that reduced embodied carbon by 75% also reduced capital expenditure by 40%. The environmental and financial outcomes were not in tension, they were the same outcome, achieved by the same approach. This is not a trade-off. It is a convergence.
The scale of the opportunity
Consider the numbers across the industry. The UK alone has approximately 45,000 hotels, inns, and guest houses. If each property refurbishes every seven to ten years, that is thousands of fitouts happening annually, each one generating embodied carbon through the manufacture, transport, and installation of new materials, and the demolition and disposal of old ones.
Now imagine that even a fraction of those refurbishments adopted circular design principles; designing for disassembly, specifying for longevity, refurbishing rather than replacing. A 75% reduction in embodied carbon per project, replicated across even a small percentage of the industry’s annual refurbishment activity, would represent a significant contribution to the sector’s overall carbon reduction.
The opportunity is not incremental. It is transformative. And it requires no new technology, no expensive retrofitting, no complex carbon trading mechanisms. It requires better design decisions, made earlier in the process, by people who understand how buildings are actually used and maintained over their lifetime.
What needs to change
Three things need to happen for the industry to address its interiors carbon problem.
First, embodied carbon from fitouts and refurbishments needs to be measured and reported alongside operational carbon. You cannot manage what you do not measure. Currently, most hotel sustainability reporting focuses on operational metrics, e.g. energy consumption, water use, waste to landfill. Embodied carbon from interiors is largely invisible in these frameworks. Until it is measured and reported, it will not be addressed.
Second, design teams need to understand construction, not just styling. The decisions that drive embodied carbon (fixing methods, material selection, services integration) are construction decisions, not aesthetic ones. They are made at concept design stage by people who need to understand how buildings are assembled and disassembled, not just how they look. Too many interior designers lack this knowledge, and too many projects suffer as a result.
Third, procurement needs to shift from purchase price to lifecycle impact. A product that costs less to buy but must be replaced every five years generates more embodied carbon over twenty years than a product that costs more but lasts throughout. The cheapest option on the purchase order is often the most carbon-intensive option over the building’s life.
Not a sustainability argument — a business argument
I have learned, over fifteen years of making this case, that leading with the environmental argument rarely changes behaviour. What changes behaviour is the commercial logic.
A 40% reduction in refurbishment capital expenditure. A 53% saving on furniture costs. 700 additional sellable nights recovered through easier maintenance. These are the numbers that get developers’ attention. The 75% carbon reduction comes as a consequence – a significant, measurable, reportable consequence — but it is the financial performance that drives adoption.
This is not cynicism. It is pragmatism. The fastest route to reducing the industry’s embodied carbon is to demonstrate that the design approach which achieves it also delivers better financial returns. When the environmental case and the commercial case point in the same direction, change happens at speed.
The hotel industry’s carbon problem is not energy. It is interiors. And the solution is not a technology — it is a design philosophy that has already been proven to work.
