2026 impact report
A shared air conditioner weighs ten times less than a new purchase.
Most of a portable AC's footprint comes from manufacturing, not from a few weeks of use. By rotating a shared fleet, serviced between every rental, and by pooling our deliveries into dense rounds, we drastically cut the CO2 per household kept cool. Here are the figures, the methodology and the sources.

Renting vs buying
The match: ≈ 15 kg vs ≈ 150 kg CO2e per household.
| Criterion | Climloc rental | Buying a new unit |
|---|---|---|
| Allocated manufacturing | ≈ 15 kg CO2e | ≈ 150 kg CO2e |
| Households served per unit | 3.4 per season | 1 |
| Km allocated to delivery | 5 km (pooled round) | 10 km (dedicated trip or customer travel) |
| Delivery CO2 | ≈ 1.25 kg | ≈ 2.50 kg |
| End of life | Workshop servicing, parts replaced | Often e-waste after a few summers |
| Outside heatwaves | The unit goes to another household | Stored 11 months a year |
On logistics, pooling avoids 1.25 kg of CO2 per delivery compared with a dedicated round trip. But the real lever remains sharing: a unit serving 3.4 households per season for at least 3 seasons brings manufacturing down to ≈ 15 kg CO2e per rental, against 150 kg for a new unit used by a single household. Our goal: increase rotations per unit and the density of our rounds, season after season.
Methodology
How we calculate.
Our calculations rely on the emission factors published by ADEME (Base Empreinte / Base Carbone), on life-cycle assessments published by portable AC manufacturers, and on our own operating data (rentals per unit, actual kilometres per round).
-
01
Manufacturing: ≈ 150 kg CO2e for a new portable air conditioner (LCA order of magnitude).
-
02
Rotations: 3.4 rentals per unit per season, measured on our fleet, over at least 3 operating seasons.
-
03
Transport: 250 g CO2e/km in a real urban cycle, freight included (ADEME).
-
04
Allocated kilometres: ≈ 5 km per delivery on a pooled round (≈ 12 stops), against 10 km for a dedicated round trip.
-
05
Scope: amortised manufacturing plus outbound and return logistics. We do not count the electricity used by the air conditioner during the rental (it depends on customer usage and the grid mix), nor the emissions of our offices and warehouses.

Limits of the calculation
What these figures do not say.
An honest impact report also shows its blind spots. Here are the three main ones.
01
We do not count electricity use
A portable AC consumes power while running, and that depends on the home, the settings and the hours of use. We leave it out of this report: for the same usage it would be identical with a purchased unit.
02
Rounds are not always dense
Early and late in the season, or across wider areas, a round has fewer stops and the kilometres allocated per delivery mechanically increase. The 5 km we use is a seasonal average, not a floor.
03
Unit lifetime is an assumption
We assume at least three seasons in the fleet, which is conservative given our observed failure rate. A unit that lasts longer improves the balance; a lost or stolen unit degrades it.
Beyond delivery
Logistics is one piece of the puzzle. The model matters too.
01
Workshop servicing
Every Climloc unit is serviced and rented out again over several seasons: that avoids manufacturing a new appliance (~150 kg CO2e saved per unit).
02
Sharing
One air conditioner serves several households each season. Cooling becomes a shared service, not an underused appliance sleeping in a basement 11 months a year.
03
Sensible use
Short-term rental encourages people to equip themselves only during real heat peaks - not to run air conditioning by default all season long.
Frequently asked questions
What people ask us most.
How much CO2 does renting save compared with buying new?
Manufacturing a new portable air conditioner represents around 150 kg CO2e. A Climloc unit serves about 3.4 households per season and stays in the fleet for at least three seasons, so amortised manufacturing drops to roughly 15 kg CO2e per rental - about ten times less than a new unit used by a single household.
What is the footprint of a Climloc delivery?
Our deliveries are pooled into rounds of about a dozen stops. That allocates roughly 5 km per delivery instead of the 10 km of a dedicated round trip, i.e. about 1.25 kg of CO2 per delivery versus 2.50 kg for a dedicated trip (250 g CO2e/km, ADEME).
Why does pooling rounds change the footprint so much?
Because every kilometre driven is shared between several customers. The denser the stops on a round, the fewer kilometres are allocated to each delivery. That is why we concentrate our slots by neighbourhood and by half-day, and why free warehouse pickup is even more frugal.
Is portable air conditioning compatible with an eco-friendly approach?
Yes, provided it is used sensibly: short-term rental, a shared fleet serviced between every rental, and pooled logistics. That is the Climloc model.
Do you count the electricity used by the air conditioner?
No, and we say so plainly. It depends on the home, the settings and the hours of use, and it would be the same for a purchased unit. This report covers amortised manufacturing and logistics.
