20 How To Master ESG and Sustainability Models

Seventeen ESG and sustainability models, each taught end to end — with the worked models to run them.

ESG and sustainability is the discipline of running a business for the long term — measuring its impact, managing climate and social risk, and turning both into strategy. This handbook teaches all seventeen models in the ESG and Sustainability category — one chapter each — from the materiality and triple-bottom-line lenses that decide what matters, through carbon accounting, climate-scenario and transition-risk analysis, to the green-finance, impact and disclosure frameworks that fund and report it. From the Triple Bottom Line and Carbon Accounting to TCFD Climate Disclosure, Science-Based Targets and Natural Capital Accounting.

What you get

The complete PDF handbook plus seventeen worked Excel models — one for every model in the book. Blue input cells you change, formula cells that respond, and a Read-me tab on each, so you can run the numbers on your own assumptions.

How every chapter is built

Read one and you can build any. Each model follows the same thirteen-section rhythm: the question it answers, what it is, who uses it, its anatomy, inputs and outputs, how to build it step by step, a worked example, strengths, limits and pitfalls, industry notes, how it connects to the other models, modern relevance, using AI on it, and a practitioner’s checklist.

The seventeen models

the Triple Bottom Line, ESG Materiality, Stakeholder Capitalism, Carbon Accounting, Climate Scenario Analysis, Transition Risk, Green Finance, Impact Investing, the Circular Economy Framework, the Sustainability Balanced Scorecard, Scope 3 Emissions, ESG Governance, Double Materiality, TCFD Climate Disclosure, Science-Based Targets, the Just Transition and Natural Capital Accounting.

The learning path

The chapters are ordered as a single connected build, not an alphabetical list — from the materiality lenses that decide what matters, through carbon, climate and transition-risk analysis, to the green-finance, impact and disclosure frameworks that fund and report it.

Who it’s for

Sustainability and ESG leaders, CFOs and investor-relations teams, impact investors and boards who must measure impact, manage climate risk and report it credibly.
