Welcome to the TRACE website !

Comprehensive information about greenhouse gas emissions is essential for decision makers to track the effectiveness of emission reduction policies in the context of the Paris Agreement on Climate. To answer that need, the Laboratoire des Sciences du Climat et de l’Environnement launches the TRACE research program funded for four years by the French national research agency  and corporate partners. In collaboration with corporate partners Thales Alenia SpaceSUEZ and TOTAL  and the Laboratoire de Meteorogie Dynamique, the TRACE program will develop new GHG emissions measurement methods going from the scale of an industrial site up to national and global GHG budgets, using satellite-mounted infrared spectrometers instruments and arrays of low-cost sensors deployed in situ, on the surface, around emitting industrial sites.
