I saw this reported in BIS-Spaceflight.
(I'm usually a few months behind in reading it) I like the "first = objective"!

https://www.thalesgroup.com/en/worldwide= /space/press-release/ascend-thales-alenia-space-lead-european-feasibility-s= tudy-data

Cannes, November 14, 2022 =E2=80=93 Thales Alenia Space, the joint company = between Thales (67%) and Leonardo (33%), has been chosen by the European Co= mmission to lead the ASCEND (Advanced Space Cloud for European Net zero emi= ssion and Data sovereignty) feasibility study for data centers in orbit, as= part of Europe=E2=80=99s vast Horizon Europe research program.

Digital technology=E2=80=99s expanding environmental footprint is becoming = a major
challenge: the burgeoning need for digitalization means that data centers i= n Europe and around the world are growing at an exponential pace, which in = turn has a critical energy and environmental impact.

The first objective of this study will be to assess if the carbon emissions= from the production and launch of these space infrastructures will be sign= ificantly lower than the emissions generated by ground-based data centers, = therefore contributing to the achievement of global carbon neutrality. The = second objective will be to prove that it is possible to develop the requir= ed launch solution and to ensure the deployment and operability of these sp= aceborne data centers using robotic assistance technologies currently being= developed in Europe, such as the EROSS IOD demonstrator.

This project is expected to demonstrate to which extent space-based data ce= nters would limit the energy and environmental impact of their ground count= erparts, thus allowing major investments within the scope of Europe=E2=80= =99s Green Deal, possibly justifying the development of a more climate-frie= ndly, reusable heavy launch vehicle. Europe could thus regain its leadershi= p in space transport and space logistics, as well as the assembly and opera= tions of large infrastructures in orbit.
