Are there any plans to include modelling of softwares, websites and mobile apps LCAs in OpenLCA, including their support infrastructure ?

In the near future ?

You mean, in openLCA databases, add processes to allow modeling of the impact of software development? Or case studies? Interesting question, I am not aware of any such plans; it is quite a difficult topic for LCA, you will need to know how much time do the developers need, which computers do they have, etc.

I mean inside an existing software, define a "Functional Unit" like "Send a 300 bytes message in a one to one discussion" in a messaging app for example and be able to calculate the CO2 impact of this functional unit.

Providing enough details like sender/receiver terminals, type of infrastructure/servers mobilised during this Functional Unit, source type of energy, necessary time for typing/reading etc ...
