I reviewed the Duke University/UNDP SDG Impact course page (instructor Cathy Clark) at the provided URL and confirmed it teaches the SDG Impact Standards and practical impact management frameworks—translating four universal IMM practices (Set Strategy, Integrate, Optimize, Reinforce) and the 5 Dimensions of Impact into tools, modules and exercises for both enterprises and investors; this makes the course a direct fit for Part 2: The Purposeful Investment Landscape (chapter “Explore the Landscape”) because it provides the accessible frameworks, terminology, decision‑making tools and concrete examples that help readers understand how to align investments and organisational practices with global standards to generate measurable SDG outcomes.
