Reuse by the numbers
Jetroque acts as a measurable lever against waste. Every user who lists an item, every confirmed match, every donation handed to a neighbour or picked up at 60 days produces aggregated impact data. We are committed to keeping this data transparent, methodologically sound, and verifiable — not a vague marketing claim.
Methodology
Three main indicators are calculated for each confirmed transaction on the platform: number of items, mass diverted (kg), equivalent CO₂ avoided (kg). The coefficients come from recognized reference databases.
1. Number of items reused
Any item that has been the subject of a confirmed transaction (completed swap or donation, or 60-day pickup validated) counts as 1. No double-counting: an item re-swapped later counts as a distinct item, but the history remains tracked.
2. Mass diverted (kg)
For each item category, Jetroque applies an average weight drawn from the ADEME (France, Bilan GES database) and Recyc-Québec databases. A few examples:
| Category | Average weight used | Source |
|---|---|---|
| 2–3-seat sofa | 45 kg | ADEME, ÉcoMobilier |
| Standard fridge | 65 kg | ADEME, ÉEQ |
| Washing machine | 70 kg | ADEME, ÉEQ |
| Dining table | 25 kg | ADEME, ÉcoMobilier |
| Adult clothing (average) | 0.4 kg | ADEME, Refashion |
| Book | 0.3 kg | ADEME |
| Small appliance (coffee maker, toaster…) | 2.5 kg | ADEME |
Weights are averages. When a user enters a weight or dimensions, that data takes priority.
3. Equivalent CO₂ avoided (kg)
For each reused item, the avoided carbon footprint corresponds to the difference between manufacturing an equivalent new item and extending the item's useful life (including transport, end-of-life, and replacement rate). Average coefficients used:
| Category | kg CO₂e / item avoided | Assumption |
|---|---|---|
| 2–3-seat sofa | ~ 70 kg CO₂e | Full life cycle vs new production |
| Standard fridge | ~ 320 kg CO₂e | New production avoided + 3 years extended use |
| Washing machine | ~ 280 kg CO₂e | New production avoided + 4 years extended use |
| Cotton garment (t-shirt) | ~ 7 kg CO₂e | 2,700 L of water + production avoided |
| Cotton garment (jeans) | ~ 25 kg CO₂e | 7,500 L of water + production avoided |
| Book | ~ 1.2 kg CO₂e | Paper production + printing avoided |
CO₂ coefficients are industry averages. They are updated annually in line with changes to ADEME databases and scientific publications (LCA — Life Cycle Assessments).
Breakdown by category (projected estimate)
Based on behaviours observed in the app and comparable data from second-hand platforms, here is the projected breakdown of reused items at full platform maturity:
Projection based on early listings in the app and benchmarks from French-language second-hand platforms. Will be replaced by real data once the statistical threshold is reached.
Nonprofit partners (60-day pickup, Quebec)
Items picked up by Jetroque under the 60-day guarantee in Quebec are systematically transferred, at no financial cost, to recognized nonprofit organizations. These partnerships are the very foundation of the platform's promise: no collected item is ever resold.
Our transparency commitments
No resale
No item collected by Jetroque is ever resold. 100% go to nonprofit partners. Contractual commitment.
Public methodology
All calculation methodologies (weights, CO₂) are published on this page and reviewed annually.
Auditable data
The figures displayed come from confirmed transactions. Auditable by any Partner City or mandated third-party auditor.
Monthly updates
Counters are updated monthly. The annual report is published in the first quarter of the following year.
Recognized sources
ADEME, Recyc-Québec, ÉEQ, Eurostat, Refashion — only publicly recognized reference sources.
Public enquiries
Any user may request clarification on a figure or coefficient at legal@jetroque.com.
And your personal impact?
Every user has, within the app, a personal impact dashboard that tracks in real time:
- Number of items you have swapped or given away
- Cumulative mass diverted from landfill
- CO₂ avoided through your activity
- Your badges and environmental challenges earned
- Your ranking within your neighbourhood (anonymous, optional)
Jetroque+ subscribers also receive a personal annual impact report in PDF format that they can share or archive.
Frequently asked questions — Impact
How does Jetroque measure its environmental impact?
For each confirmed transaction, three indicators: number of items, mass diverted (kg) based on average weights from ADEME/Recyc-Québec, and equivalent CO₂ avoided (difference between new production and extended use). Public, auditable methodology.
Are the figures displayed verified?
Yes. The figures are calculated automatically from confirmed transactions in the app. The unit coefficients (weight, CO₂) come from recognized databases (ADEME, Recyc-Québec, Eurostat) and are reviewed annually.
Where do items collected under the 60-day guarantee go?
In Quebec, they are systematically transferred, at no financial cost, to a recognized nonprofit partner (reuse centres, ressourceries, community organizations, schools). Jetroque never resells collected items.
Can I view the detailed impact report?
This page is the public summary report. A detailed annual report is produced for Partner Cities and Jetroque Pro subscribers. Jetroque+ users receive their own personal impact dashboard in the app.
What about users outside Quebec?
Users in France, Belgium, Switzerland, Morocco, etc. benefit from the same impact indicators in the app for their own transactions. The rollout of the 60-day pickup and nonprofit partnerships outside Quebec is gradual and announced country by country.
