Experience gathered during the operation of the EU ETS has confirmed that sectors and subsectors are at risk of carbon leakage to varying degrees, and that free allocation has prevented carbon leakage.
Leis an taithí a fuarthas le linn oibriú EU ETS, dearbhaíodh go bhfuil earnálacha agus fo-earnálacha ann a bhfuil riosca sceitheadh carbóin ag roinnt leo, bíodh nach ionann an riosca sin ó cheann go chéile acu, agus go gcoisctear sceitheadh carbóin tríd an saor-leithdháileadh.
