MSCI’s “Sustainable Investing” resource is included because it documents the practical data, ratings, indexes and reporting tools—including ESG Ratings, sustainability and climate indexes, sustainability reporting services and impact solutions—that wealth managers and investors use to measure, report and integrate material sustainability and climate risks across asset classes; the page’s stated capabilities and metrics (eg. thousands of sustainability clients, large benchmarks and extensive data coverage) directly support Part 2’s goal of equipping readers to understand the purposeful investment landscape and fit squarely into the book’s Traditional Wealth Management chapter and the sub-chapter A Green Look at How They Work by showing the concrete frameworks and outputs readers should request (ESG ratings, carbon footprints, alignment with net‑zero goals and regulatory reporting) when evaluating sustainable investment options.
