This measure was primarily set up to reduce the costs of public lighting which can represent up 45 % of the electricity bill of Commons. Or, whereas this measure fits perfectly in sustainable common development goals, by limiting the power consumption of the territories, no study has so far characterized if this could effectively limit the negative impact of artificial lighting on biodiversity.
Hatua hii kimsingi ilianzishwa ili kupunguza gharama za taa za umma ambazo zinaweza kuwakilisha hadi 45% ya bili ya umeme ya Commons. Au, ingawa hatua hii inalingana kikamilifu katika malengo endelevu ya maendeleo ya pamoja, kwa kupunguza matumizi ya nguvu ya maeneo, hakuna utafiti ambao umebainisha hadi sasa kama hii inaweza kuzuia athari hasi ya mwangaza bandia kwenye bayoanuwai.
