Webinar: Invisible No More: Tracking Ship Emissions from Space Date: September 23, 2026

Organizers: GMV, European Space Agency (ESA), Ocean OS, Satellite Applications Catapult, and partners

Join us for "Invisible No More: Tracking Ship Emissions from Space," a joint webinar bringing together the EO4SEM (ESA-funded) and EMMA (Innovate UK-funded) projects to demonstrate how satellite remote sensing and AI-powered modeling are making maritime pollution visible.

What to Expect

• EO4SEM Project Insights: Discover how satellite missions (Sentinel-5P/TROPOMI, PRISMA, EnMAP, GHGSat) and advanced inversion models fill gaps in AIS tracking to quantify $\text{NO}_x$, $\text{CO}_2$, and methane emissions across open sea shipping lanes and ports.
• EMMA Coastal Modeling: Learn how ground-truthed AI, air quality sensor networks, and satellite data combine to act as an "environmental weather forecast" for port zones like Plymouth Sound.
• Regulatory Alignment: Explore how Earth Observation data supports European Green Deal, Fit for 55, and FuelEU Maritime goals by providing independent, scalable emission baselines.

2. TROPOMI-Derived NOX Emissions from Sea Shipping: Estimates Along Major Lanes and for Individual Vessels

• Authors: M. M. N. Diouf, H. Vignesoult, A. Fortems-Cheiney, F. Chevallier, A. Héraud, S. Beirle, J.-P. Jalkanen, A. Maragkidou, F. G. Brandão, R. Gini, D. Sengupta, J. Vitorino, A. Delavois, and G. Broquet
• Overview: This presentation introduces advanced atmospheric inverse modeling techniques developed within the EO4SEM project. By assimilating Sentinel-5P/TROPOMI $\text{NO}_2$ imagery and combining it with Automatic Identification System (AIS) tracking, the study demonstrates monthly $\text{NO}_x$ emission budgeting across European seas, flux-divergence modeling along major shipping lanes, and plume-detection methods capable of estimating instant $\text{NO}_x$ emissions from individual large vessels.

EO4SEM Consortium Highlights Maritime Emission Research at EGU 2026

May 3–8, 2026

The EO4SEM Consortium will present its latest research findings at the European Geosciences Union (EGU) General Assembly 2026 in Vienna, Austria.

Researchers from across the project will deliver two key scientific presentations showcasing how satellite remote sensing, data fusion, and inverse modeling advance maritime emission tracking from global shipping corridors down to individual vessels:
