ESG & Sustainability
How environmental, social and governance issues reach cash flows, risk and value, explained for Indian markets.
ESG is no longer a side topic for Indian investors. The top 1,000 listed companies file a Business Responsibility and Sustainability Report, the largest must have key figures independently checked, carbon now has a price for cement, aluminium and refining plants, and new labour and data protection laws carry real costs. This section explains the ideas, the rules and the numbers behind all of it, in plain language.
Start with the five core guides, or jump to a sub-section: foundations, environment and climate, social, corporate governance, reporting, ratings and data, sustainable finance, responsible investing and valuation, the players who set the rules, and the India ESG Rulebook. Every guide links to its glossary terms, and worked examples are clearly marked when the numbers are made up.
