For those passionate about biodiversity and natural capital the real power of this book lies in its direct applicability to the "immeasurables". Terms like "biodiversity loss," "ecosystem health," and "species value" are often treated as qualitative or even moral arguments. How to Measure Anything in Project Management provides the toolkit to turn these into quantitative risks, making them directly comparable to financial or operational risks. I strongly recommend this book to those working in public policy, non-profits, or corporate Environmental, Social, and Governance roles. Let’s start collecting the right data to inform robust data driven decision making, to ensure that regenerating natural capital is part of every project that affects it.
