Building Geneva's circular economy, together
LémanLoop is a not-for-profit, community-owned initiative. We believe sustainability works best when it's open, shared, and rooted in the communities it serves.
How it started
A lanyard problem hiding in plain sight
Every Geneva conference ends the same way: thousands of lanyards tossed in a bin. After one too many events watching perfectly reusable lanyards head to landfill, Rahul Jha set out to close that loop.
The idea was simple: a deposit-and-return system, volunteer-powered collection, and an open platform that any event organiser or community member could contribute to. No shareholder interests. No proprietary lock-in. Just a shared commons for a shared problem.
LémanLoop is structured as a not-for-profit association under Swiss law, with community governance baked in from day one. Every contributor — volunteer, organiser, or donor — is a co-owner of the mission.
Rahul Jha
Founder
Passionate about Geneva's role as a hub for international cooperation and sustainable innovation. Building LémanLoop as a community commons — open by design, mission-first.
Our model
Open by design. Community by choice.
LémanLoop is built on four commitments that are written into how we govern and operate.
Not for profit
We are structured as a Swiss association (à but non lucratif). Any financial surplus is reinvested directly into the programme — expanded coverage, better tooling, or lanyard library growth. No shareholder ever benefits.
Community ownership
Volunteers, organisers, and donors who contribute to LémanLoop are co-owners of the mission. Governance decisions are made openly, with proposals and votes accessible to all members.
Open source
The entire LémanLoop platform — from the grading algorithm to the CO₂ calculation model — is published under an open licence. Fork it, adapt it, or run your own loop in another city.
Open science
Our impact data, lanyard grade distributions, CO₂ savings methodologies, and research findings are published openly. Good environmental data should be a public good, not a proprietary asset.
Support the mission
Help the loop keep growing
LémanLoop runs on volunteer energy and community generosity. Donations fund lanyard library expansion, volunteer training, platform development, and our open science data publishing.
Every franc stays in the programme. As a not-for-profit association we publish our accounts annually.
