The limitation of the EU ETS to flights within the EEA between 2013 and 2016 was agreed in Regulation No.421/2014, pending the agreement to be reached in 2016 in ICAO on a single global market based measure, to be implemented from 2020.
Määruses (EL) nr 421/2014 lepiti kokku, et ajavahemikul 2013–2016 kohaldatakse ELi HKSi üksnes EMPs toimuvate lendude suhtes, kuni 2016. aastal jõutakse ICAOs kokkuleppele ühtses ülemaailmses turupõhises meetmes, mida hakatakse rakendama 2020. aastal.
