The Commission shall assess that obligation, with a view to submitting, by 2023, a legislative proposal to increase it in the event of further substantial costs reductions in the production of renewable energy, where necessary to meet the Union's international commitments for decarbonisation, or where justified on the grounds of a significant decrease in energy consumption in the Union.
Déanfaidh an Coimisiún measúnú ar an oibleagáid sin, d'fhonn togra reachtach a thíolacadh faoi 2023 chun é a ardú i gcás ina bhfuil tuilleadh laghduithe costais suntasacha i dtáirgeadh fuinnimh inathnuaite, i gcás inar gá chun gealltanais idirnáisiúnta an Aontais maidir le dícharbónú a chomhlíonadh, nó i gcás in bhfuil údar leis mar gheall ar laghdú suntasach i dtomhaltas fuinnimh san Aontas.
