Isabelle's personal commitments operate on several levels: firstly, she is involved in sports clubs and associations, including one in a small village in Haute Saône - Bousseraucourt, with 55 residents. The association organises inter-village competitions with villages located in the Vosges Mountains to support and maintain activities in rural communities. In addition, Isabelle runs the women's network EDF Interp'Elles which has 750 members, as well as the sub-network Interp'Elles Ile de France with 360 members. In November, she will participate in a human adventure known as the "Amazon Green Tree Raid, with five other female colleagues," in Guyana. She also devotes one day per year to voluntary work for the Telethon.
