NerdWallet’s “ESG for Beginners” is included as a clear, up‑to‑date primer that defines environmental, social and governance criteria, explains how ESG differs from SRI and CSR, summarizes evidence on potential returns and lower downside risk, and gives practical, action‑oriented steps for building an ESG portfolio (DIY vs robo‑advisors) plus examples of ESG stocks and funds; this makes it a direct fit for Part 2: The Purposeful Investment Landscape, Chapter “Exploring the Landscape,” where readers need accessible definitions, screening tools and starter steps to align investments with values (and, as noted in the NotebookLM comment, its practical guidance can be translated into book tools such as an ESG‑inspired traffic‑light system).
