The Center for Data Innovation recently spoke with Mathieu Carlier, founder of Everimpact, a France-based company developing an AI-driven platform that measures greenhouse gas emissions in real-time. Carlier explained how Everimpact combines satellite imagery, ground sensors, traffic data, and other information to identify emission sources, support decarbonization efforts, and help organizations track their progress.
David Kertai: What does Everimpact offer?
Mathieu Carlier: As cities, ports, shipping companies, and many other industries work to reduce carbon emissions and meet climate targets, many still lack timely information about where emissions are occurring. Traditional carbon accounting often relies on periodic activity data, such as fuel consumption and traffic patterns, combined with standard emissions factors. These approaches can provide useful estimates but often cannot show how emissions change in real time or pinpoint where changes are occurring. Without timely information, organizations can struggle to identify emerging emission hotspots, respond to changes quickly, or determine whether decarbonization efforts are successful.
Everimpact addresses this gap with an AI-driven platform that measures greenhouse gas emissions and air pollution in real-time. The platform combines multiple data sources to create a detailed picture of emissions across cities, transportation networks, ports, ships, industrial sites, and forests. Organizations can use this information to identify emission sources, track changes over time, and evaluate whether decarbonization efforts are working.
Kertai: What types of data does your platform collect and analyze to measure emissions?
Carlier: We use several types of data to measure emissions at different scales. Satellite imagery provides broad geographic coverage, while ground sensors capture local air-quality conditions. We also incorporate traffic, weather, and other activity data that can help explain changes in emissions. For maritime applications, continuous emissions-monitoring systems installed on vessels can measure emissions directly from their exhaust.
The platform brings these sources together to show how emissions vary across locations and activities. This combination gives organizations a more detailed picture of emissions than any single data source can provide and helps them understand how environmental and operational conditions affect emissions.
Kertai: How does your platform turn emissions data into actionable recommendations?
Carlier: Everimpact analyzes emissions data to attribute emissions to specific sources, identify hotspots, and highlight opportunities for reductions. Different industries can use these insights in different ways. A city could use the data to evaluate transportation policies, while a shipping company could identify inefficient vessel operations. A forest manager could use emissions and carbon-absorption data to evaluate the results of conservation or reforestation efforts.
The platform can also help organizations evaluate whether those interventions work. By comparing emissions before and after a change, users can measure the effect of a particular action and determine whether it achieved the intended reduction. This gives organizations a way to connect emissions measurement with concrete decarbonization decisions.
Kertai: How does your platform differ from traditional carbon-accounting tools?
Carlier: Traditional carbon accounting generally estimates emissions using activity data and standard emissions factors. Everimpact supplements those approaches with direct measurements and real-time data, providing a more precise picture of where emissions occur and how they change.
This approach can reveal opportunities that conventional estimates may overlook. In shipping, for example, real-time emissions measurements can help operators identify inefficiencies and adjust vessel operations accordingly. The resulting data can also support regulatory reporting, carbon taxes, and financial instruments that require organizations to demonstrate their emissions performance.
Kertai: Could you share a few use cases of our platform in action?
Carlier: Currently twelve major European cities, including Paris, Athens, Zurich, and Birmingham, use our platform to monitor CO₂ emissions across their urban areas and transportation corridors. In Paris, for example, the city combines emissions information with traffic data to identify areas where emissions are increasing and inform transportation and infrastructure decisions.
The Port of Antwerp-Bruges in Belgium uses our platform for port-wide emissions monitoring and to track emissions from individual vessels as they enter and leave. Shipping companies also use Everimpact to support emissions reporting and compliance with European carbon regulations, with customers including MSC and TotalEnergies. These applications show how organizations can use real-time emissions data for both day-to-day decisions and longer-term decarbonization planning.
