Chief of Naval Operations (CNO) Adm. Jonathan Greenert congratulates 24 commands across the globe via video teleconference (VTC) at the Pentagon during a VTC award ceremony to recognize the CNO Environmental Award recipients for the Fiscal Year 2013. By using VTC technology the Navy is able to save money and reduce the carbon imprint that would have resulted from the various command representatives traveling to meet for a physical presentation of the awards.
