I'm not surprised the press release didn't provide links. Except for aspirations it appears to be an empty high ceremony management process framework. Maybe hitting the COP event with PR was more significant than having something that could actually be pointed to. It's not clear how the issues raised in other comments here are to be met.
The lowest impact data centres will be those in places where there is ample renewable energy and/or low external temperatures for cooling, such as Iceland and Norway.
If the gains are purely in terms of repurposing empty urban buildings then there are better options. We currently have a separation between residential housing and workplaces. The commuting that results from that should be seen* as unsustainable. The best solution would be to convert some workplace space into housing for people who work in the remaining workplaces and move other work out into the surrounding, currently residential, communities. This is not aided by the short-sighted conversion, in areas like mine, of the few remaining former industrial sites into housing.
* And probably will be when it's too late.
