抄録（英）
The space debris modelling and risk assessment office of CNES is in charge, on the flight dynamics domain, of the activities linked with the analysis, the modelling, the development of tools and the R&D activities related to Space Surveillance and Tracking, space debris and the French Space Operations Act. The activities developed within the CNES space debris modelling and risk assessment office, are therefore structured around key technical domains, as the active and passive detection of space objects from ground or from space, the correlation and cataloguing of the objects orbiting the Earth, the short and long term propagation of the space objects, the computation of on-orbit collision risk in case of close approaches or on-ground casualty risk in the event of a re-entry as well as the evaluation of the long term evolution of the orbital environment. The work that will be presented will be focused on this very last key technical activity, this is the long term evolution of the orbital environment. The presentation will provide a focus of the most recent work done by CNES on this topic, as the analysis evaluating the decoupled effect of the background and of the future space activity on the long term evolution of the orbital population. A focus will be also given to the last CNES efforts to develop a space object criticality index allowing to identify the missions posing the biggest threat to the orbital environment. Finally, these latest developments will be presented on the perspective of a new framework being developed by CNES with the aim to have a global view of the state of the orbital environment at every moment.
