The Environmental Cost of Commuting
How work-from-home policies can significantly reduce your carbon footprint and help combat climate change.
WFH saves 242 kg of CO₂ per person per year
That's a 5% reduction in your annual carbon footprint.

What the Research Says
University of Melbourne research shows that working from home 1.5 days per week reduces national annual greenhouse gas emissions by about 1.21 Mt CO₂-e. Working from home 4 days per week reduces emissions by 5.76 Mt CO₂-e annually.

Your Commute's Carbon Footprint
The environmental impact of your commute depends on how you travel. Here's how different transport methods compare:
CO₂ Emissions per Kilometre
* Electric car emissions depend on the electricity grid. In Western Australia, where coal still makes up a significant portion of generation, the benefit is reduced compared to renewable-heavy grids.Source: Australian Government Green Vehicle Guide, Climate Council
Perth's Potential Impact
With over 1 million workers in the Perth metropolitan area, the collective impact of work-from-home policies could be transformative.
Scenario: 20% of Perth Workers WFH 2 Days/Week

The Compounding Environmental Benefits
The environmental benefits of WFH extend beyond just eliminating your commute:
- Reduced office energy use: Less heating, cooling, and lighting in commercial buildings
- Less road maintenance: Fewer cars means less road resurfacing and construction
- Reduced runoff pollution: Fewer cars means less oil, tyre particles, and brake dust washing into waterways
- Lower manufacturing demand: Less wear on vehicles means fewer replacement parts needed
But What About Home Energy Use?
Critics argue that WFH simply shifts emissions from offices to homes. However, research shows this isn't the case. The University of Melbourne study found that even accounting for increased residential energy use, WFH still results in significant net emissions reductions.
The key reason: heating and cooling a single home is more efficient than heating/cooling a large commercial building, especially when that building is only partially occupied.
