Currently, the committee's consultative function extends only to the commission itself and the Council of Ministers, and just five specific areas.
But Dr Wulf-Mathies, the commissioner in charge of European regional policy, said this should be reviewed at next year's inter-governmental conference which will serve to update the Maastricht Treaty.
'I would call for the consultative role of the committee to be reinforced, the list of areas in which consultation is compulsory to be increased and its consultative function to be extended to the European Parliament,' she said.
A spokesperson said this could be extended to include, for example, environmental protection, agriculture and planning.
Dr Wulf-Mathies also called for the European Union to play a greater role in urban regeneration.
