Who You’ll Work With

Meet Our CSO

Chief Sustainability Officer — Change Rebellion

Millie Bushill

Fractional CSO · ESG Strategy · CSRD Compliance · Green Claims

Change Rebellion’s Chief Sustainability Officer brings deep expertise across ESG strategy, materiality assessment, and regulatory compliance — with a particular focus on making sustainability actionable for organisations who are serious about doing it properly, not just talking about it.

Working directly with clients — not through layers of account managers — Millie combines rigorous technical knowledge with the kind of plain-speaking approach that Change Rebellion is built on. If you’re tired of sustainability consultants who leave you with a beautiful report and no idea what to actually do, this is a different experience entirely.
