Leading CDP, the global non-profit that runs the world’s largest independent environmental disclosure system, Sherry Madera is pioneering a new age of Earth-positive economics, a model that places sustainability at the heart of value creation.

Drawing on her unique background as an investment banker, Economic Ambassador for the City of London to Asia, capital markets chief, author and entrepreneur, Sherry is putting environmental data at the core of strategic business decision-making and performance. Earth-positive economics recognizes that environmental health is not a constraint on prosperity – but a precondition for it.

Sherry speaks regularly in global forums on topics including sustainable finance, FinTech, international trade, data policy and geopolitics. She is the author of the newly published book, Navigating Sustainability Data: How Organizations can use ESG Data to Secure Their Future.

Sherry’s journey through finance, international trade, market data infrastructure, and sustainability gives her a unique perspective on where value, markets, and impact intersect – challenging the status quo and making sense of complexity.

Establishing the Future of Sustainable Data Alliance (FoSDA) at Davos in 2020, Sherry is a key architect behind the role of sustainable data in powering investment and operational decisions.

Prior to joining CDP, Sherry held previous senior global roles including Senior Vice President, Public Policy for Mastercard and Chief Industry and Government Affairs Officer, London Stock Exchange Group.

Sherry has recently joined the Washington Post Intelligence Energy and Climate Council as a Founding Member and sits on the GX Acceleration Agency’s Global Advisory Council.

Sherry has previously held roles advising Hong Kong’s Cyberport and APEC’s Sustainable Finance Development Network and sat on the Board of Directors of Sondrel Limited and the University of Nottingham.
