Working close to home: how much CO2 (and how many hours) do you actually save per year?

The office weighs 23 kg of CO2e per year; a daily car commute can weigh 960. ADEME figures by transport mode, the annual calculation, and why a well-connected coworking space is the first climate action.

We calculated that your desk at Zecoworking emits 23 kg of CO2e per year. In all honesty: that is not the figure that matters most. The real climate issue of any office is the trip to get there. A daily car commute can emit 40 times more than the office itself. Here is the calculation, and what a well-connected coworking space actually changes.

What each kilometre emits, by mode

Emissions per person per kilometre, grams of CO2e

Petrol car218 g
Paris-region bus≈ 76 g
Suburban rail / RER≈ 5 g
Metro≈ 4 g
Bike, walking0 g
Sources: ADEME, Impact CO2 (petrol car 218 g/km); Île-de-France Mobilités / SNCF operating data (bus, rail, metro). Rounded values.

The order of magnitude leaves no room for debate: between a car and the metro the ratio is about 1 to 50. No « eco-friendly » badge in the window offsets a car park that fills up morning and evening.

The same thing, over a working year

Take a modest commute: 10 km each way, 220 working days. Here is what the year weighs by mode, next to the workstation itself:

A year of commuting (20 km/day, 220 days), kg of CO2e

A year of car commuting (20 km/day)≈ 960 kg
The same year by bus≈ 334 kg
The same year by RER≈ 21 kg
A year of your desk at Zecoworking23 kg
The same year by bike0 kg
Calculation: per-km emissions above × 4,400 km/year. Zecoworking desk: 2025 site electricity spread over 53 desks.

This is the most important chart of our sustainability series: the car bar dwarfs everything else. Choosing an office reachable without a car is a climate lever 10 to 40 times more powerful than anything the operator can do inside its walls. We say this even though our walls are among the most energy-sober on the market: proof that we are not just selling you green paint.

And the hours? The commute’s other currency

Going from an hour of daily commuting to twenty minutes means recovering about 150 hours a year: nearly four working weeks, returned to your team, your clients or your family. Companies that set up close to where their people live see it everywhere: punctuality, recruitment, retention.

The Zecoworking choice: proximity first

Our coworking space in Courbevoie is built on that logic: Victor Hugo and Paul Doumer bus stops 1 minute away on foot, Esplanade de La Défense 10 minutes, Courbevoie station 12 minutes. Your Hauts-de-Seine employees come by bus, train, bike or on foot, and your corporate mobility plan writes itself.

The logical next step: make the trip yourself. Book a visit, time it, and compare with your current lease. Our available offices are waiting for the team that lives next door.
