How to Make Your Workplace Greener
Quick answer: The average office worker generates 2–4 tonnes CO₂e per year from work-related activities. Commuting is the largest source, followed by office energy, business travel, and procurement. Working from home 2–3 days per week can cut commute emissions by 40–60%.
Workplace Emission Sources
| Category | Average CO₂e/employee/year | % of Work Emissions |
|---|---|---|
| Commuting | 1.0–2.5 tonnes | 40–50% |
| Office energy (heating, cooling, lighting) | 0.5–1.0 tonnes | 20–25% |
| Business travel | 0.3–1.0 tonnes | 15–25% |
| IT and digital | 0.2–0.5 tonnes | 5–15% |
| Procurement and supplies | 0.1–0.3 tonnes | 5–10% |
8 Actionable Tips
1. Advocate for Remote Work
Working from home 2–3 days per week can reduce commute emissions by 40–60%. If your job allows it, negotiate a hybrid schedule. The energy cost of home working is typically offset by eliminating the commute.
2. Green Your Commute
- Cycle to work: Zero emissions, improves health
- Public transport: 40–80% fewer emissions than driving alone
- Carpool: Share rides with colleagues
- Electric vehicle: If driving is necessary
3. Reduce Business Travel
- Video calls first: Only travel when face-to-face is essential
- Train over plane: For trips under 800 km
- Combine trips: Visit multiple clients/sites in one trip
- Virtual conferences: Attend online when possible
4. Optimize Office Energy
- Turn off lights and screens at end of day
- Adjust thermostat: 1–2°C lower in winter, higher in summer
- Natural ventilation: Open windows instead of AC when weather allows
- LED lighting: 75% less energy than fluorescent
5. Go Digital
- Print less: Use digital documents and e-signatures
- Cloud storage: Reduce server room energy
- Digital receipts: Skip paper receipts
- Email cleanup: Delete old emails and attachments (they use server energy)
6. Green Procurement
- Choose sustainable suppliers: Look for environmental certifications
- Buy recycled paper and supplies
- Reduce packaging: Order in bulk, avoid excess packaging
- Lease equipment: Manufacturers handle end-of-life recycling
7. Improve Office Waste Management
- Set up proper recycling stations
- Compost food waste in the kitchen
- Eliminate single-use plastics: Provide reusable cups, plates, cutlery
- Donate old electronics: Instead of sending to landfill
8. Lead by Example
- Form a green team: Get colleagues involved
- Track emissions: Measure and report workplace carbon footprint
- Set targets: Aim for measurable reductions
- Share results: Celebrate wins to maintain momentum
Frequently Asked Questions
Does working from home actually reduce emissions?
Yes, for most office workers. A typical commute produces 1–3 kg CO₂e per day. Home energy use for working adds only 0.5–1.0 kg CO₂e. Net savings: 0.5–2.0 kg per day worked from home.
How do I convince my employer to go green?
Frame it in business terms: energy efficiency saves money, sustainability attracts talent and customers, and many green initiatives have payback periods under 3 years. Start with free actions like turning off lights.
What about video call emissions?
A one-hour video call produces roughly 0.05 kg CO₂e. A return domestic flight produces 200 kg. Video calls save 4,000x more emissions than they create.
