Energy Efficiency Titles, also called White Certificates, are titles certifying energy savings resulting from the realisation of specific energy efficiency interventions. They have been introduced with Italian Ministerial Decrees of July 20th 2004 with the purpose of promoting the realisation of energy efficiency improvement interventions.

Energy efficiency improvement is certified by GME (Energy Markets Management) issuing Energy Efficiency Titles (TEE); every TEE corresponds to 1 tep (Tonnes of oil equivalent) of energy saved; TEE are exchanged on a market regulated by GME or through bilateral negotiations.
