Tool 
WWLCAW or World Wide LCA Workshop was created by CPM and is now administered by IMI. 

Purpose 
WWLCAW is a web-based (Intranet or Internet) LCA-project support. It allows anyone to set up a LCA- project for a geographically distributed project and all projects have access to fully documented impact assessment data. WWLCAW has discussion forums where users easily can discuss e.g. quality of data.

Use 
Software is not bug free and the user interface is complex. Datasets can be uploaded to or downloaded from the site and the tool calculates impact assessment indices as well as full LCAs 

Evaluation 
The tool is being developed but it looks promising.
