The Union and its Member States have been endeavouring to make progress towards reaching an international agreement to reduce greenhouse gas impacts from aviation since 1997 and they have legislation in place since 2008 to limit the climate change impacts from aviation activities through the EU ETS that has been in operation since 2005.
Tá an tAontas agus a Bhallstáit tar éis iarraidh dul chun cinn a dhéanamh maidir le teacht ar chomhaontú idirnáisiúnta maidir le tionchair an gháis cheaptha teasa ón eitlíocht a laghdú ó bhí 1997 ann, agus tá reachtaíocht i bhfeidhm acu ó 2008 amach chun tionchair an athraithe aeráide ó ghníomhaíochtaí eitlíochta a theorannú trí AE ETS, córas atá i bhfeidhm ó bhí 2005 ann.
