The Project/Programme Sustainability Platform (PPSP) site, a generic users' platform that can integrate sustainability logbooks and ratings, has been replaced by the Urban Sustainability Management Platform (USMP) City Logbooks site at USMS.site

Like the PPSP site,  the USMP City Logbooks site is based on the Project/Programme Sustainability Logbook (PPSL)  site PPSL.site, but is much more flexible and allows indicator sets to be used for logbooks (specifically, the ISO 37120 and ISO 37122 city indicator sets).

Registered USMP users can subscribe to a Trial Subscription that allows PPSL reference frameworks and the ISO indicator sets to be used create a logbook for each of up to two projects.

Details of Full Subscriptions are sent to registered users when they register.

An announcement summarising the PPSP's features is available in Resources. A similar announcement will be made available for the USMP that replaces both PPSP and PPSL sites.
