Alongside the European Commission, the Covenant benefits from full institutional support, including from the Committee of the Regions, which has supported the initiative since its inception; the European Parliament, where the two first signing ceremonies were held; and the European Investment Bank, which assists local authorities in unlocking their investment potentials.
Ud over Europa-Kommissionen har pagten fuld opbakning fra EU’s øvrige institutioner, herunder Regionsudvalget, der har støttet initiativet siden ikrafttrædelsen, Europa-Parlamentet, hvor de to første underskriftsceremonier blev afholdt, og Den Europæiske Investeringsbank, der hjælper lokale myndigheder med at kortlægge deres investeringspotentiale.
