Through detailed discussions of data modeling, governance, tooling, and cultural transformation, the book demonstrates how finance, engineering, and ESG teams can work together to make sustainability measurable, auditable, and actionable. It equips organizations to align cost optimization with climate objectives, building operational excellence that is both economically sound and ecologically responsible.
