About the Canton of Geneva:

  • Geneva is one of the 26 cantons of Switzerland.
  • The canton of Geneva is itself composed of 45 municipalities (one of them is the city of Geneva).
  • The canton of Geneva represents a total area of around 280 km2, with a total population of 500’000 inhabitants.

My responsabilities:

Management of a team of 7 scientists and technical specialists with the following missions:

  • Enforce cantonal and federal (swiss) legislation on the territory of Geneva for the environmental protection of air quality as well as protection against noise, especially for urban planning projects
  • Monitor the air pollution with a network of stationary measurement stations (link to our website)
  • Prepare content for public communication about air quality, through various communication channels (website, social media, press, etc), and publication of an annual report on “Air quality” (link to our reports)
  • Trigger pollution alerts in case legal thresholds are exceeded and to set-up emergency and enforceable actions to reduce pollution (link to our page explaining the Stick’Air plan)
  • Evaluate the effectiveness of the long term actions and strategy taken by the State of Geneva to reduce air pollution
  • Prepare strategic noise maps and to determine if sound proofing measures are needed
  • Test new IOT technologies with the objective of deploying networks of low cost sensors in order to get real time and “where it is” determination of the pollution (air and noise)
