Expert advisory, minus the excess
Fusion CSO is a boutique climate and sustainability consulting firm working directly with clients, or in partnership with leading consultancies, law firms and deal teams.
Seasoned pros. We are a network of senior leaders in the second half of their careers, combining a portfolio of advisory, board, and project-based work.
