With Yumana’s platform, VINCI uncovered the power of a single, structured program to reveal its most promising green initiatives and scale environmental action across 120 countries.
As a global leader operating across 120 countries, VINCI faces a dual challenge: reducing its environmental footprint while mobilizing a highly decentralized workforce.
While thousands of initiatives were emerging locally, the Group needed a way to identify what worked, evaluate environmental impact, and scale best practices across business units.
VINCI aimed to engage more than 200,000 employees in its environmental transition, identify the most impactful initiatives emerging across its regions, and accelerate the deployment of those solutions across all business lines.
To meet these goals, the Group launched WE NOW, its global environmental program, and created the Environment Prize to bring structure, visibility, and momentum to thousands of local actions.
Together with VINCI, Yumana deployed its best practices management software to power the entire program:
Through this joint approach, VINCI moved from intention to measurable environmental action, transforming scattered local solutions into a structured program with measurable impact.
The Environment Prize surpassed expectations and unlocked Group-wide momentum.

A decentralized ecosystem became a coordinated engine for environmental performance, powered by employee-led innovation.
“We needed to move quickly to bring together many employees around the Environment Prize.
Yumana was a real partner in the launch of the Prize and the deployment of the platform. The team was responsive to our needs and knew how to challenge us to make our program a success.”
