About

The Greater Paris Metropolis has launched a strategic program to deploy ethical and sustainable AI in public policy. The initiative focuses on two main goals:

  1. Accelerate AI adoption in local governments and public services.

  2. Build a dynamic, internationally recognized urban AI ecosystem.

To implement this, the Métropole created the “ApproprIAtion Métropolitaine” program — a free, three-phase initiative for municipalities :

  • Training: Build AI literacy and identify local use cases.

  • Experimentation: Fund and support pilot AI projects.

  • Scaling: Expand successful solutions across the metropolitan area.

Current tracks include:

  • IA ECOPILOT (energy efficiency in public buildings – 60 cities)

  • IA Delivery Zones (urban logistics – 11 cities)

  • IA-BTP Match (construction material reuse – 3 EPTs)

  • IA Administration (process optimization – 26 cities)

Upcoming in 2025: new tracks on city center attractiveness, and noise monitoring.

AI solutions concerning noise monitoring answer different public issues such as :

  • Detect and monitor traffic noise in real time

  • Predict peak noise periods in busy neighborhoods

  • Identify and classify noise sources (e.g., cars, construction, nightlife)

  • Monitor and regulate construction site noise

  • Map noise pollution dynamically across the city

  • Analyze citizen complaints to detect recurring noise issues

  • Alert authorities when noise exceeds legal thresholds

  • Support urban planning with AI-driven acoustic insights

The Metropolis is actively seeking innovative startups to co-develop and scale impactful AI solutions for urban challenges
