More than a race, an agent of change
Run further, act more justly
The Harmonie Mutuelle 20km de Paris is not just an iconic sporting event: the event embodies a strong desire to take concrete action in the face of current environmental and social challenges.
Because every step counts, every gesture has weight, we have chosen to place our event within a responsible, collective and sustainable approach.
For several years, we have placed positive impact at the heart of our organization. This means rethinking our practices, collaborating with committed partners, and mobilizing all participants around the values of respect, solidarity, and environmental sustainability.
Our ambition is not limited to reducing our footprint: it aims to create an event model that inspires and motivates, serving profound and lasting change.
In 2025, the greenhouse gas emissions of the Harmonie Mutuelle 20km de Paris amount to 1,851 tCO₂e, or 0,06 tCO₂e per runner.
A structured and measured approach
Our commitment translates into concrete actions, supported by demanding standards: the Anti-Waste Law for a Circular Economy, the ISO 26000, ISO 20121 and ISO 14001 standards, as well as the charter of 15 eco-responsible commitments from the Ministry of Sports and the World Wide Fund for Nature.
These guidelines are not mere obligations: they are the foundation of our vision, which we bring to life at every stage of the organization.
Course cleaning, waste reduction, promotion of eco-friendly practices, raising awareness among runners, volunteers and partners : everything is being done to make the Harmonie Mutuelle 20km de Paris an innovative event.
And because change cannot be decreed, but is built, we measure our progress each year, readjust our actions and innovate to go even further.
It is this dynamic of continuous improvement, rooted in reality and driven by the enthusiasm of thousands of runners and committed stakeholders, that allows us to build together a fairer, cleaner, more responsible event.
