What is the aim of the app?

Geco Air is a free mobile application developed by IFPEN to help users reduce their travel-related air pollution. By analysing GPS data and vehicle specifics, it estimates emissions such as CO₂, NOx, and particulates. Users input their vehicle registration to tailor the model, or select a standard vehicle. The app automatically detects journeys and transport modes, calculating a ‘mobility score’ to reflect environmental impact. Personalised advice is provided to encourage eco-friendly driving and transport choices. All data is anonymised, securely stored, and used solely for research purposes to support air quality improvements.

Who is IFPEN?

IFP Energies nouvelles (IFPEN) is a leading French organisation in energy, transport and environmental research. With public support, it addresses energy and climate challenges, promotes sustainable mobility, and supports a more diverse energy mix, boosting jobs and economic growth across France and Europe. Within this mission, IFPEN developed the Geco air app, funded by Ademe, to help reduce travel-related air pollution. The app is free, ad-free, and collects anonymised emissions data, used solely for research and to support local air quality improvements.

How will LENS Support app development?

As part of the LENS project, Geco Air will be further enhanced to support light vehicle users, helping them track and lower their mobility footprint. The tool will form part of a wider system, combining large-scale data collection, cloud-based models, and useful features like local air quality updates—focusing efforts on refining emissions calculations for better user guidance.
