Capgemini and GMV have announced the availability of the “World Emission” platform demonstrator, funded by the European Space Agency (ESA).

Aimed at mapping global greenhouse gas (GHG) and atmospheric pollutant emissions, it leverages data from the Copernicus satellites as well as satellites from international entities such as NASA or JAXA and brings complementary information to ground base measurements and traditional bottom-up inventories.

GHG and air pollutants emission inventories are used by various stakeholders, including decision-makers, governments, and research organisations, in the battle against climate change and the pursuit of a sustainable world.

Emission abatement measures

These inventories enable the assessment of progress made in implementing emission abatement measures and play a crucial role in determining future environmental policies.

Current bottom-up inventories use different methodologies from country to country and have large uncertainties resulting from sometimes inaccurate data and emission factors.

Satellite observation data complements and enables validation of ground-based measurements by providing high accuracy data that is refreshed more frequently, with better spatial coverage.

Therefore the European Space Agency started the “World Emission” project in March 2022 to create an inventory service based on state-of-the-art satellite observation and inverse modeling.

The data processing platform was developed by Capgemini teams in co-construction with some of Europe’s most renowned research institutes, including the Laboratory for Climate and Environmental Sciences in France, the Max Planck Institute in Germany, the University of Liege in Belgium, the Barcelona Supercomputing Center in Spain, and the Cyprus Institute in Cyprus, and Kayrros, a French start-up specialised in earth observation technology and environmental intelligence.

Data processing tool

Since its launch, the project has engaged and brought together a community of users, scientists, and experts, whose role is to evaluate datasets for different atmospheric species and ensure that World Emission provides a precise, reliable, and high-performing inventory service.
