Across the world, office buildings stand fully lit, air-conditioned, and stocked with supplies — even when they’re half empty. In the age of remote and hybrid work, we’re not just wasting space. We’re burning energy, overproducing waste, and maintaining infrastructure that doesn’t match how we actually live and work.
This isn’t just inefficient. It’s an environmental problem.
The Scale of Office Resource Use
Modern office buildings consume vast amounts of:
- Electricity: for lighting, elevators, computers, and endless devices
- HVAC energy: for heating and cooling large, often under-occupied spaces
- Water: from restrooms, kitchens, and landscaping
- Cleaning chemicals: used daily regardless of how many people are present
- Office supplies and consumables: like paper, plastics, and packaging
Even during pandemic-era remote work, many buildings stayed “on” — not because of need, but inertia. Today, with hybrid models in place, many companies still run full operations regardless of occupancy levels.
Why “In-Person Culture” Comes at an Environmental Cost
The push to return to office is often framed around collaboration, culture, or productivity. But rarely does the conversation include what this decision means for:
- Carbon emissions from building operations
- Food and packaging waste from catered lunches and office kitchens
- Excess energy use for lighting and climate control
If only 30% of the workforce shows up on a given day, but 100% of the building is powered, that’s not culture — it’s consumption.
Office Buildings Are Among the Worst Climate Offenders
In major cities, commercial buildings are often the largest contributors to local greenhouse gas emissions. For example:
- In New York City, buildings account for nearly 70% of carbon emissions, with commercial real estate playing a major role.
- HVAC systems alone are responsible for a large portion of energy-related COâ‚‚ emissions, especially in older or poorly insulated buildings.
- Many offices rely on fossil fuel-based electricity or gas-powered systems for heating and cooling.
And yet, the occupancy rate in some major office buildings sits below 50%, especially midweek.
Hybrid Work Isn’t Green by Default — It Requires Smart Infrastructure
While remote work can reduce emissions, hybrid models without smart building management can actually increase energy use. Why?
- Lights and HVAC often run at full capacity regardless of how many people are inside.
- Buildings aren’t always zoned to selectively power only used floors or areas.
- Cleaning schedules and deliveries may remain unchanged, even if occupancy drops.
Without adaptive systems or usage-based controls, a half-empty office can be just as environmentally harmful as a full one.
Hidden Costs of Keeping Offices Running
Beyond energy, consider:
- E-waste from constant tech upgrades and replacements
- Overproduction of furniture, signage, and promotional materials
- Single-use kitchenware for convenience
- Excess printing and paper waste despite digital alternatives
Remote workers are often more mindful of their energy usage at home. But in an office, those costs are out of sight — and out of mind.
Alternatives That Reduce Waste Without Losing Connection
The solution isn’t to abandon all shared workspaces — it’s to right-size and rethink them.
Some emerging ideas include:
- Coworking hubs close to residential neighborhoods to reduce commuting
- Office hoteling — where desks are reserved only when needed
- Flexible leases and modular spaces that scale with actual usage
- Green retrofits to reduce building emissions with smart systems and renewable energy
The key is efficiency and intentionality, not blanket mandates or vanity square footage.
Remote Work Supports a More Sustainable Office Model
When done right, remote work:
- Decreases peak-hour demand on office systems
- Reduces food waste, packaging, and resource overuse
- Lowers electricity use by shifting it to more efficient, decentralized settings
- Encourages digital over physical communication, reducing printing and materials
Instead of every company powering their own underused headquarters, remote and distributed work allow for more shared, efficient spaces and lower environmental impact overall.
Holding Corporations to Smarter Standards
Just as companies are being urged to cut emissions in their supply chains, they should be asked:
- What’s your building occupancy rate vs. energy use?
- Do you track and report waste from unused office days?
- Are your return-to-office policies consistent with your climate pledges?
Without transparency and accountability, greenwashing thrives while real waste continues.
Final Thoughts: Space Without Purpose Is Just Pollution
The era of empty but fully powered office buildings is a symptom of outdated thinking — the same kind that values appearances over sustainability, and control over efficiency.
A truly modern workplace doesn’t just adapt to how people want to work — it adapts to how the planet needs us to work.
If a space is going to exist, it should serve a purpose. Otherwise, it’s just a footprint we can no longer afford.
