School Commute Emissions
Annual commuting CO₂e from headcount, distance and mode mix — Scope 3 category 7.
The school run is a city-scale emission source — car-dropped students emit ~6× bus riders per km. Model your school's mode mix; the bus-shift savings row is the PTA conversation starter.
GHG Protocol Scope 3 category 7. Mode mix is everything: a car commute emits ~6× a bus commute per km. The survey beats the assumption — poll your team's actual modes once a year and update the shares here.
Screening-level estimate using published average emission factors. Audited disclosures (BRSR, GRI, CDP) require primary activity data and verified factors — confirm with your sustainability auditor.

How to use School Commute Emissions
- 1Enter headcount and the average one-way commute distance.
- 2Split the workforce by mode (car, two-wheeler, transit; rest assumed walking/cycling).
- 3Read annual tCO₂e, per-employee intensity and the WFH/mode-shift savings.
Why use School Commute Emissions?
- ✓Scope 3 category 7 done properly: mode mix, not averages
- ✓WFH sensitivity: what each remote day is actually worth
- ✓Mode-shift savings quantified for transport-policy decisions
- ✓Survey-ready structure — update shares yearly
Frequently asked questions
How big are commuting emissions compared to office operations?+
Often bigger: a 100-person office with typical Indian mode mix and 15 km commutes generates ~85–120 tCO₂e/yr from commuting — frequently exceeding the office's own electricity footprint. It's the Scope 3 line service firms most underestimate until they survey it.
How much carbon does one work-from-home day per week save?+
Proportional: one WFH day cuts commute emissions ~20% (1/5 of trips). For the 100-person office above, that's ~20 t/yr — comparable to a small rooftop solar array's offset. Hybrid policy is a carbon instrument; the savings row makes that visible.
How should I collect commute data?+
A 4-question annual survey: distance, primary mode, days in office, secondary mode. Response rates above 60% make the mode shares defensible. Plug the results in here — the math is then GHG Protocol category 7 compliant with a documented method.
Which mode shift matters most?+
Car to anything: at ~170 g/km a solo car commute emits 6× a bus passenger and ∞× a cycle. Even car→two-wheeler halves it. The 10%-shift row prices the realistic intervention — parking policy, transit subsidies, cycle facilities — in tonnes you can claim.
