Lanciato nel [[2005]], rappresenta un pilastro fondamentale della politica dell'[[Unione Europea]] sul [[cambiamento climatico]].
Il sistema copre più di 10.000 impianti industriali e energetici la cui potenza termica nominale supera i 20 MW, responsabili di quasi la metà delle emissioni di [[Anidride Carbonica|CO<sub>2</sub>]] all'interno dell'Unione e di circa il 40% delle emissioni di tutti i [[gas serra]]. <ref>http://www.minambiente.it/export/sites/default/archivio/allegati/emission_trading/2010-06-10_GuidaEsplicativa_raccolta_dati_9a2__2__rev.pdf</ref><ref>http://europa.eu/rapid/pressReleasesAction.do?reference=MEMO/08/35&format=HTML&aged=1&language=IT&guiLanguage=en
