FM newsroom – ESG, sustainability strategy. As property owners move from climate pledges to real action, the complexity of cutting emissions across building portfolios is becoming clear. From data gaps to budget pressures, facility managers are navigating a challenging path — but a structured approach can unlock both carbon and cost savings.
From ambition to implementation
Decarbonising real estate is no longer just an environmental ambition; it is fast becoming an operational and financial necessity. Property operators face mounting pressure from ESG requirements, CRREM (Carbon Risk Real Estate Monitor) and national climate targets, while the risk of buildings becoming “stranded assets” is sharpening the focus on action.
Yet turning strategy into reality is far from straightforward. Incomplete data makes it difficult to assess energy-saving potential, skills shortages slow progress, and fragmented supplier markets create operational friction.
Bridging the gap with an integrated strategy
In many organisations, long-term sustainability goals collide with short-term budget constraints and limited resources. Experts increasingly argue that an integrated approach is essential — one that improves transparency, prioritises measures based on impact and enables scaling across portfolios.
Central to this is a deep understanding of buildings and their technical systems, allowing operators to develop robust decarbonisation roadmaps rather than relying on isolated projects.
The concept of “climate return on investment” is gaining traction as a guiding principle, aiming to maximise CO₂ reduction per euro invested. A five-step approach used in decarbonisation projects — for example, by Apleona — is outlined by Dr Michael Lange, Chief Digital Officer & Green Real Estate Lead at Apleona GmbH, for the Facility Management portal.
Five steps towards lower emissions
-
Build a solid data foundation
Reliable data is the starting point for any decarbonisation strategy. Detailed insights into energy consumption, operating patterns and plant conditions enable informed decisions and help identify inefficiencies.
Digital monitoring systems and structured asset assessments can reveal consumption patterns, highlight anomalies and pinpoint assets with high modernisation potential, forming the basis for strategic planning.
-
Optimise operations first
Significant savings can often be achieved simply by improving day-to-day operations, without major capital expenditure. Adjusting temperature settings, aligning operating hours with actual use, avoiding simultaneous heating and cooling, and fine-tuning systems can deliver quick wins.
Digital tools and predictive controls can further enhance efficiency by dynamically managing building systems based on weather and usage patterns.
-
Target quick-payback investments
Smaller upgrades — such as replacing inefficient pumps, installing LED lighting or insulating accessible pipework — can deliver strong results with relatively low disruption and short payback periods.
Careful prioritisation is key, particularly where budgets are limited, ensuring measures are selected based on impact, feasibility and operational risk.
-
Plan major upgrades strategically
Achieving deeper emissions reductions requires larger investments, including heat pumps, photovoltaic systems and advanced building automation. These projects benefit from careful coordination with other upgrades, such as modernising heating systems or improving energy distribution.
A clear roadmap helps align timelines, budgets and technical dependencies while reducing implementation risks.
-
Don’t overlook the building fabric
Although often outside the traditional scope of facility management, improvements to the building envelope — such as insulation, façade upgrades or shading solutions — can significantly reduce heating and cooling demand and improve overall efficiency.
Real-world results
Long-term optimisation programmes show the potential impact of a structured approach. In one large multi-site portfolio, electricity consumption was nearly halved over more than 15 years through a combination of operational improvements, targeted investments and data-driven energy management.
Operational optimisation delivered particularly strong climate returns, with more than 3 kg of CO₂ avoided per euro invested on average when the emission factors of the CRREM approach are used as a basis for calculating the energy savings. Smaller efficiency measures achieved around 2–3 kg, while major investments delivered about 1 kg per euro. Dr. Michael Lange points out that this does not take into account that many measures are refinanced through reduced energy.
A transformation led by facility management
Decarbonisation is ultimately a continuous transformation process rather than a one-off project. Success depends on combining reliable data, technical expertise and clear prioritisation to turn climate targets into measurable progress.
As organisations seek to balance sustainability with economic performance, facility management is emerging as a key driver of change — translating strategy into practical action and long-term value creation.
