The EDISON project is part of a growing global awareness of the impact of human activities on the environment and aims to gain a better understanding of the sources of urban pollutant emissions in order to put in place effective reduction policies.

EnhanceD emIsSiOn iNventory


The EDISON project aims to improve air quality in France by enhancing existing inventories of atmospheric pollutants and focusing on emission sources. It is based on a monitoring tool combining satellite data (Sentinel-5P, Sentinel-3), existing inventories, atmospheric modelling, real-time data on activities (transport, buildings, industry, land use, etc.) and socio-economic data.

EDISON will provide more accurate measurements, finer spatial resolution and greater speed for greenhouse gas emissions and air quality inventories, particularly for CO2 (carbon dioxide), NO2/Nox (nitrogen dioxide) and fine particles PM1/PM2.5. Municipal managers and regulators can thus visualize the impact of their activities on air quality and identify opportunities to reduce emissions.

Thanks to EDISON, decision-makers will be able to plan priority actions to improve air quality in metropolitan France, based on accurate results and real-time data. In this way, the project is helping to combat air pollution and promote a healthier, more sustainable environment for all.

Application site(s)

Metropolitan France



  • Copernicus for measuring emissions :
    • Sentinel 3 (SY_2_SYN and SY_2_AOD)
    • Sentinel 5P (TROPOMI NO2L2)
  • EGNSS for georeferencing, activity and socio-economic datasets, and existing emissions inventories based on declarative data.


  • Socio-economic: population groups, population density, economic sectors, etc.
  • Activity data: land registry (Open Street Map), transport (Open Transport Map), traffic, energy consumption, land use, etc.

Results – Final product(s)

At the end of the EDISON project, municipal managers and regulators will be able to benefit from a platform for visualizing the impact of their activities on greenhouse gas (CO2) emissions and air quality (NO2/NOx, PM1/PM2.5), as well as the reduction opportunities available to them. This will be made possible by improving the accuracy of measurements, spatial resolution, and speed of emissions inventories. This will enable them to put in place priority action plans to reduce their environmental impact.
