The Commission shall assess that target with a view to submitting a legislative proposal by 2023 to increase it where there are further substantial costs reductions in the production of renewable energy, where needed to meet the Union's international commitments for decarbonisation, or where a significant decrease in energy consumption in the Union justifies such an increase.
Déanfaidh an Coimisiún measúnú ar an sprioc sin, d'fhonn togra reachtach a thíolacadh faoi 2023 chun é a mhéadú i gcás ina bhfuil tuilleadh laghduithe ar na costais suntasacha i dtáirgeadh fuinnimh inathnuaite, i gcás inar gá chun gealltanais idirnáisiúnta an Aontais le haghaidh dícharbónú a chomhlíonadh nó i gcás in bhfuil bonn cirt leis an méadú sin mar gheall ar laghdú suntasach ar thomhaltas fuinnimh san Aontas.
