Introduction
Facilities management is moving from operational support to strategic decarbonisation. For many organisations, buildings are no longer just places of work. They are major sources of energy use, carbon emissions, procurement impact, waste generation and climate-related risk. This creates a new responsibility for facilities management providers: to help clients move from general sustainability commitments to measurable, evidence-based emissions reduction.
The Science Based Targets initiative Buildings Criteria has made this shift more important. The criteria recognise that the buildings value chain includes a wide range of actors, including those involved in building ownership, development, management and occupation. This means facilities management companies may have a direct role in supporting science-based targets, especially where they manage operational emissions across client sites.
For facilities management providers, the opportunity is clear. The market is no longer only asking for clean buildings, safe workplaces and reliable maintenance. Clients increasingly need energy data, carbon evidence, Scope 3 reporting support, reduction roadmaps, supplier engagement and credible progress against net-zero commitments. Facilities management can become one of the most practical routes for turning climate targets into operational action.
Why facilities management matters for decarbonisation
Buildings consume energy every day. Heating, cooling, lighting, ventilation, hot water, lifts, security systems, IT rooms, catering spaces, cleaning operations and plant rooms all contribute to a building’s operational footprint. These emissions are often influenced by facilities management decisions.
Facilities management teams are close to the real operational levers:
- how buildings are heated and cooled,
- how HVAC systems are maintained,
- how lighting is scheduled,
- how plant rooms are operated,
- how waste is collected and segregated,
- how cleaning products and consumables are purchased,
- how contractors are selected,
- how maintenance is planned,
- how building data is monitored,
- how energy-saving measures are implemented.
This makes facilities management a practical bridge between corporate climate strategy and daily building performance.
A company can publish a net-zero target, but the actual reduction often happens through operational changes: better controls, efficient equipment, lower-carbon procurement, reduced waste, refrigerant management, energy monitoring and planned replacement of fossil-fuel systems. Facilities management is where many of these changes are delivered.
The connection between SBTi and facilities management
The SBTi Buildings Criteria focuses on emissions linked to buildings, including in-use operational emissions and, where relevant, upfront embodied emissions from new construction or acquisition. For facilities management companies, the most relevant area is usually in-use operational emissions from managed buildings.
In practical terms, facilities management providers may need to understand whether their managed-building emissions are material enough to fall under buildings-specific target-setting requirements. This depends on the company’s business model, its level of control or influence, its emissions boundary and the share of emissions linked to owned or managed buildings.
The key point is that facilities management companies should not treat SBTi as only a corporate head-office exercise. Their role may extend into the operational emissions of client buildings, particularly where they manage energy-intensive systems or provide whole-building services.
Facilities management as a property management function
Many facilities management providers do not own the buildings they operate. They may not hold the energy contracts. They may not control major capital expenditure. However, they often manage the day-to-day systems that influence building performance.
This creates a specific SBTi challenge: the company may influence emissions without fully owning or financially controlling the assets that generate them.
That does not make the role irrelevant. It means the emissions boundary must be carefully defined.
A facilities management provider needs to identify:
- which emissions are directly controlled by the FM company,
- which emissions are controlled by the client,
- which emissions are controlled by the landlord,
- which emissions sit in Scope 1 or Scope 2,
- which emissions sit in Scope 3,
- which emissions can be reported as managed-site operational emissions,
- which reductions can be claimed directly,
- which reductions should be reported as client-enabled or client-site improvements.
This distinction is essential. Poor boundary setting creates double counting, weak claims and validation risk. Good boundary setting creates confidence, credibility and commercial value.
The whole-building approach
One of the most important concepts for facilities management is the whole-building approach. In building decarbonisation, partial data is often misleading. A building may have landlord-controlled areas, tenant-controlled spaces, shared areas, plant rooms, common corridors, receptions, catering areas and specialist equipment. If only one part is measured, the emissions picture is incomplete.
For facilities management providers, this means a credible decarbonisation programme should aim to collect whole-building operational data where possible. This includes electricity, gas, heat, cooling, refrigerants and other fuels across both landlord and tenant-controlled spaces.
The whole-building approach is important because facilities management often works across boundaries. A cleaning contract may cover shared and tenant spaces. A maintenance team may service central plant. Security and reception may operate in common areas. HVAC decisions may affect the whole workplace. Energy optimisation may require cooperation between landlord, tenant and FM provider.
Facilities management companies should therefore build data systems that can separate control while still understanding the whole building.
What FM companies should measure
A facilities management company preparing for SBTi-aligned reporting should begin with a full greenhouse gas inventory. This should cover its own corporate footprint and the emissions associated with its managed services.
Key data categories include:
Scope 1
Scope 1 emissions may include company vehicle fuel, gas used in offices controlled by the FM provider, direct fuel combustion and refrigerant leakage from systems under direct control.
Scope 2
Scope 2 emissions include purchased electricity, heat, steam or cooling for sites under the company’s operational or financial control.
Scope 3
Scope 3 is often the largest and most complex area for facilities management. Relevant categories may include purchased goods and services, capital goods, fuel- and energy-related activities, waste, business travel, employee commuting, leased assets, use of sold products or managed-site operational emissions depending on the reporting boundary.
For FM providers, important Scope 3 sources often include:
- cleaning chemicals,
- hygiene consumables,
- uniforms,
- maintenance materials,
- contractor services,
- waste treatment,
- employee commuting,
- business travel,
- purchased equipment,
- outsourced services,
- client-site operational emissions where applicable.
Managed-building emissions
For facilities management providers, managed-building emissions are the strategic issue. These emissions may not always sit directly in the FM company’s Scope 1 or Scope 2 inventory, but they can be highly relevant to the company’s service impact and client reporting value.
Managed-building emissions may include:
- electricity use,
- gas and heating fuels,
- district heat,
- cooling,
- backup generation,
- HVAC-related refrigerant leakage,
- energy used in common areas,
- tenant-controlled operational energy,
- landlord-controlled operational energy,
- specialist operational systems,
- building services plant.
A strong FM carbon programme should create a managed-site emissions register. This register should capture site name, client, building type, location, floor area, energy data, refrigerant records, operational hours, occupancy assumptions, data quality and reduction actions.
Why floor area matters
Many building-related targets use emissions intensity, commonly expressed as kgCO₂e per square metre. This makes floor area a critical data point.
Facilities management companies should not treat floor area as a minor administrative detail. Different clients may use different definitions: gross internal area, net internal area, lettable area or local measurement standards. If floor area is inconsistent, intensity targets become unreliable.
FM providers should standardise their floor area methodology across client sites. They should also document assumptions, include common areas where relevant and maintain the same denominator across base year and target years.
This is basic data governance, but it is often where building carbon reporting becomes weak.
From maintenance to emissions reduction
Facilities management companies should move beyond reporting and position themselves as delivery partners for decarbonisation.
High-impact FM interventions include:
- heating and cooling set-point optimisation,
- HVAC scheduling,
- boiler replacement planning,
- heat pump feasibility support,
- LED lighting upgrades,
- lighting controls,
- BMS optimisation,
- plant-room maintenance,
- refrigerant leak management,
- predictive maintenance,
- insulation and draught reduction support,
- efficient cleaning schedules,
- low-carbon cleaning products,
- waste reduction and segregation,
- water efficiency measures,
- supplier rationalisation,
- electric fleet transition,
- route optimisation for mobile teams.
The strongest programmes do not simply list actions. They quantify expected impact, assign ownership, track implementation and compare actual performance against baseline.
The no-new-fossil-fuel-equipment direction
A major direction in building decarbonisation is the move away from new fossil-fuel equipment. For facilities management providers, this has direct operational consequences.
FM companies should identify where fossil-fuel systems are present, who owns them, when they are expected to reach end of life and what low-carbon alternatives are technically and financially feasible.
The relevant equipment may include:
- gas boilers,
- direct gas-fired hot water systems,
- fossil-fuel heating equipment,
- fossil-fuel cooking equipment,
- fossil-fuel power generation used in buildings,
- non-emergency backup systems.
The FM provider may not always control replacement decisions. In many cases, the client or landlord owns the asset. However, facilities management can still provide the evidence needed for decision-making: lifecycle cost, carbon impact, operational risk, replacement timing, maintenance history and low-carbon technology options.
Reporting without overclaiming
Facilities management companies must be careful with carbon claims. If an FM provider supports a client to reduce emissions, that does not automatically mean the FM provider can claim the full reduction as its own corporate footprint reduction.
Better reporting separates:
- direct operational reductions,
- managed-site reductions,
- client-approved interventions,
- reductions enabled through FM services,
- advisory recommendations,
- opportunity pipeline,
- avoided emissions estimates,
- verified reductions.
This distinction protects credibility. It also gives clients better information. A professional FM decarbonisation report should show what was directly reduced, what was influenced, what was recommended and what still requires client investment.
The role of procurement
Facilities management is procurement-heavy. Cleaning chemicals, paper products, uniforms, spare parts, tools, subcontractors and maintenance equipment all carry embedded carbon.
A credible FM SBTi pathway must therefore include supplier engagement. This means asking suppliers for better emissions data, prioritising low-carbon alternatives, reducing unnecessary consumables and shifting procurement decisions away from cost-only evaluation.
Important procurement actions include:
- supplier carbon questionnaires,
- product-level emissions data collection,
- environmental product declarations where available,
- low-carbon cleaning products,
- concentrated cleaning chemicals,
- reduced single-use consumables,
- circular uniforms and textiles,
- repair-first maintenance policies,
- supplier sustainability scoring,
- contract clauses for emissions reporting.
Procurement is not separate from facilities management. It is one of the main routes through which FM companies can reduce Scope 3 emissions.
Data quality and evidence
SBTi-aligned work requires more than ambition. It requires evidence.
Facilities management companies should build an evidence hierarchy:
- Metered energy data.
- Utility invoices.
- Landlord or client-provided energy data.
- BMS or sub-meter data.
- Contractor service records.
- Refrigerant logs.
- Waste transfer notes.
- Supplier-specific emissions data.
- Product-level emissions data.
- Spend-based estimates where better data is unavailable.
Spend-based data may be acceptable as an early screening method, but it should not be the long-term standard for high-impact categories. The direction should be toward activity-based and supplier-specific data.
A practical roadmap for FM providers
A facilities management company can follow a staged approach.
Stage 1: Baseline
Build a full Scope 1, Scope 2 and Scope 3 inventory. Identify which emissions are controlled, influenced or client-owned.
Stage 2: Applicability screening
Assess whether buildings-related emissions are material and whether buildings-specific target-setting requirements apply.
Stage 3: Data system
Create a managed-site carbon data template covering energy, refrigerants, floor area, waste, procurement and interventions.
Stage 4: Target modelling
Model corporate targets and building-related targets. Separate in-use operational emissions from embodied emissions where relevant.
Stage 5: Reduction planning
Create a practical decarbonisation roadmap focused on energy, HVAC, refrigerants, procurement, fleet, waste and client-site operational improvement.
Stage 6: Client integration
Add carbon reporting into FM contract management, quarterly business reviews and annual ESG reporting.
Stage 7: Progress reporting
Report annual emissions, intensity performance, absolute reductions, data quality improvement and reduction measures implemented.
Commercial opportunity for facilities management
SBTi is not only a compliance topic. For facilities management, it is a commercial opportunity.
Clients increasingly need suppliers that can support Scope 3 reporting, procurement requirements, ESG disclosures and net-zero delivery. FM providers that can produce credible carbon data and implement reduction actions will be more valuable than providers that only deliver traditional maintenance and workplace services.
The future FM contract will not only ask:
“Can you operate this building?”
It will ask:
“Can you help reduce the operational carbon of this building and prove it with evidence?”
This is where facilities management becomes strategic.
Conclusion
Facilities management has a direct role in building decarbonisation. The sector sits close to the operational decisions that shape energy use, emissions, procurement, waste and workplace performance.
For FM providers, SBTi alignment should not be treated as a paper exercise. It should become a structured operating model: clear emissions boundaries, whole-building data, accurate floor area, Scope 3 procurement evidence, fossil-fuel replacement planning, energy efficiency measures and transparent reporting.
The companies that move first will be better positioned for client tenders, ESG expectations and long-term net-zero delivery. Facilities management is no longer just about keeping buildings running. It is about helping buildings decarbonise.
For this reason, facilities management SBTi alignment should be treated as both a compliance requirement and a commercial opportunity for FM providers.
