Indeed there are several models available for Europe. All of hte EU-15 (and possibly now 25) are required by eurostat to create input-output tables and many also create environmental data in the same format. There is currently a large-scale research project at several European institutions to create a large database of european and other EIO-LCA models called the EXIOPOL project. (see
http://www.feem-project.net/exiopol/ ) Contacting someone on that project would probably be your best bet for obtaining data.
