The company has received more than 120,000 requests for takedowns of 457,000 links since a May court ruling enabled Europeans to ask for the removal of embarrassing personal information that pops up with a search of their names.
"We need to balance the right to information against the rights of privacy," Schmidt said before he and other panel members heard testimony from Spanish privacy and right-to-know experts.
They include removal requests by former politicians criticized for their policies, criminals who don't want their convictions known, bad reviews for architects or teachers, and comments people wrote about themselves that they now regret.
Google said today it could not immediately provide information on how many requests for takedowns have been approved and how many have been denied but would release the information soon.
Falque-Pierrotin said coherent guidelines are needed, but privacy regulators declined an invitation to join Google's panels.
"Google asked us to join as experts. We are not experts - we are regulators," she said from Paris. "We also want to hear other points of view and we will have our own consultation process.
