Celeste LeCompte references some deeper looks in her article Can Videoconferencing Save the Earth? In Short: No. Her's is a more global (truly) approach than some of the more internal organization experimental approaches I've discussed before, but this provides a nice reminder: evidence based management should be based on all the evidence, not just that from our own firm. Video conferencing can provide great overall value, especially if it is saved and used as part of an organization's knowledge management approach. However, doing it because it's "green" may be a good, but not significant justification.
