Did you know that buildings consume about 40% of the world’s energy and generate roughly 36% of global CO₂ emissions? Our homes, offices, schools, and other buildings are indeed major energy users and carbon emitters. This makes them a critical battleground in the fight against climate change.
Reaching “net zero” (balancing the carbon emissions we produce with those we eliminate) by mid-century requires us to make buildings significantly more efficient and cleaner. And who’s on the front lines of this effort? Facilities management.
In simple terms, facilities managers are the professionals who keep our buildings operational, managing heating and cooling, lighting, plumbing, maintenance, and compliance. By adopting smart strategies, they play a pivotal role in reducing a building’s carbon footprint and steering us toward net-zero carbon emissions.
In this blog post, we’ll explore five key areas where facilities management is advancing climate action: Energy Management, Building Decarbonisation, Data & Measurement, Operational Strategies, and Compliance & Reporting. We’ll also highlight how SustainZone helps facilities teams accelerate their sustainability efforts.
Energy Management: Smarter, More Efficient Buildings
One of the fastest ways to cut emissions is by using energy more wisely and minimising waste. Estimates suggest that about 30% of the energy used in buildings is wasted due to inefficiencies, such as lights left on in empty rooms or heating and cooling systems running unnecessarily.
Smart Technology Upgrades
Modern facilities management addresses this waste through smart technology upgrades. Real-time energy monitoring systems allow managers to track electricity usage and identify wasteful patterns. If an AC unit runs overnight by mistake, a dashboard alerts the team to turn it off.
Building management systems equipped with sensors and automation adjust lighting and HVAC systems automatically, ensuring energy is used only when needed. These smart controls can reduce energy waste by up to 30% while maintaining occupant comfort.
High-Efficiency Equipment
Facilities managers are replacing outdated equipment with high-efficiency alternatives. A prime example is lighting — switching to LED bulbs, which use up to 90% less energy than incandescent bulbs. Studies show that LED retrofits in commercial buildings can reduce lighting energy use by about 49%.
HVAC systems, often the largest energy consumer in buildings (accounting for 40–60% of total use), are another focus. Smart HVAC controls, high-efficiency units, and modern thermostats that respond to occupancy can significantly lower energy costs while maintaining comfort.
Combining efficient lighting, optimised HVAC systems, and improved insulation allows facility managers to greatly reduce energy consumption — cutting both carbon emissions and utility bills.
Building Decarbonisation: Cutting Fossil Fuels from Buildings
Beyond improving energy efficiency, the next major step is transitioning away from fossil fuels.
Heat Pump Revolution
Heat pumps are central to decarbonisation. These electric devices provide heating and cooling by transferring heat rather than burning fuel. Modern heat pumps deliver 2 to 5 times more heat energy than the electricity they consume, making them 2–4× more efficient than gas furnaces.
Replacing gas furnaces or oil boilers with heat pumps drastically cuts direct carbon emissions. As electrical grids adopt more renewables like solar and wind, the carbon footprint of heat pumps decreases even further. Experts suggest widespread heat pump adoption could cut global CO₂ emissions by several gigatons annually.
Electrification Strategy
Facilities managers are also embracing electric alternatives, such as induction stoves and electric boilers, wherever possible. Electrifying building operations allows buildings to run entirely on clean electricity as grids decarbonise.
On-Site Renewable Energy
Many facilities install solar panels on rooftops to generate clean electricity on-site, reducing reliance on the grid. Solar combined with battery storage enables buildings to store energy for use at night, further reducing emissions.
Building Envelope Improvements
Improving the building envelope — its walls, windows, and insulation prevents energy waste. Upgrading to double- or triple-glazed windows, for example, can reduce heat loss by up to 60% compared to single-pane glass, substantially lowering emissions from heating and cooling.
Data & Measurement: Tracking Progress to Net Zero
You can’t manage what you don’t measure. Successful facilities management starts with accurate data.
Establishing Carbon Baselines
Facilities managers first calculate the building’s carbon baseline, its current emissions from electricity, fuel use, and other sources. This establishes a starting point to track progress and set reduction targets, often using specialised software or consultants.
IoT Sensors and Smart Analytics
IoT sensors and energy management platforms provide real-time insights into energy consumption, equipment performance, and occupancy levels. Managers can identify inefficiencies quickly and optimise operations accordingly.
Automated Reporting
Advanced analytics can automatically optimize systems and simplify carbon accounting. This streamlines reporting for regulators or corporate ESG programs, reducing last-minute reporting challenges.
By making energy and carbon data visible, facilities managers are empowered to drive continuous improvement and keep net-zero strategies on track.
Operational Strategies: Optimising Space, Schedules, Waste, and Water
Not every carbon reduction measure requires major equipment upgrades. Smarter day-to-day operations also deliver significant savings.
Smart Space Utilisation
Optimising how space is used prevents unnecessary heating, cooling, and lighting. Occupancy sensors, flexible scheduling, and space management software allow facilities to consolidate activities and reduce energy use in underutilised areas.
Equipment Scheduling
Efficient equipment scheduling, such as timing ventilation systems or cleaning routines, prevents wasted energy. Small operational tweaks can add up to large savings.
Waste and Water Management
Waste reduction programs, recycling, and procurement changes help lower emissions associated with material production and disposal.
Water conservation also plays a role. Using low-flow fixtures, repairing leaks, and optimising cooling towers reduces both water and the energy required for its treatment. In the U.S., about 13% of electricity consumption goes toward supplying and treating water, so every drop saved avoids additional carbon emissions.
Compliance & Reporting: Navigating Regulations like NYC’s Local Law 97
As governments adopt stricter climate regulations, facilities managers play a key role in ensuring compliance.
NYC’s Local Law 97
This landmark law mandates emissions limits for New York City buildings over 25,000 square feet, with penalties for exceeding set thresholds. Facilities managers must monitor emissions, implement reduction projects, and file annual compliance reports. Failure to comply could cost millions in fines.
Global Regulatory Trends
NYC is not alone — building performance standards and carbon reporting mandates are expanding worldwide. The EU is requiring zero-emission new buildings, and many jurisdictions are following suit. Transparent reporting and proactive energy management are becoming mandatory.

Conclusion: Facilities Management as a Climate Hero
From the outside, facilities management may appear limited to fixing equipment or managing daily operations. But as we’ve seen, it’s at the heart of rethinking how buildings consume energy and resources.
With smart technology, cleaner systems, data-driven strategies, efficient operations, and regulatory compliance, facilities managers are transforming buildings from climate liabilities into climate solutions.
Achieving net-zero emissions is one of the defining challenges of our time. While solar farms, electric vehicles, and reforestation make headlines, the buildings we inhabit offer enormous, often overlooked opportunities. By equipping facilities managers with the right tools, training, and support, including partners like SustainZone, we unlock one of the largest climate solutions available today.
Behind the scenes, in control rooms and boiler rooms, facility managers are quietly driving a global transformation, fine-tuning systems, monitoring performance, and steadily shrinking carbon footprints.
