ESG framework for company analysis

ESG stands for Environmental, Social and Governance. It is a set of non‑financial criteria that investors use to assess a company’s sustainability and ethical impact.

Environmental factors examine how a firm manages natural resources, carbon emissions, waste and energy efficiency. Social factors look at labour practices, community relations, health & safety, and diversity. Governance evaluates board structure, shareholder rights, transparency, and anti‑corruption measures.

In the NISM Series XV exam, ESG is tested as a qualitative overlay to traditional financial analysis. Candidates must be able to link ESG scores to risk premiums, valuation adjustments and compliance requirements.

The Environmental pillar measures a company's impact on the planet. Typical indicators include carbon intensity, water usage, renewable energy share, and waste recycling rates. Analysts often source this data from annual sustainability reports or third‑party databases such as CDP.

The Social pillar assesses how a firm manages relationships with employees, suppliers, customers and communities. Key metrics are employee turnover, gender diversity, health & safety incidents, and community investment. In India, labour law compliance and skill‑development programmes are heavily scrutinised.

The Governance pillar looks at board composition, executive remuneration, shareholder rights, and anti‑corruption policies. Governance lapses can lead to regulatory penalties and reputational damage, directly affecting stock price volatility.

While each pillar is distinct, they interact. For example, poor environmental practices can trigger social backlash, which in turn may lead to governance reforms. Understanding these inter‑dependencies is crucial for a holistic company analysis.

Regulators and rating agencies assign different weights to each pillar based on industry relevance. Energy firms receive higher environmental weighting, whereas financial institutions are judged more on governance.

Exam candidates should remember that the weighting scheme is not fixed; the question will specify the weights or ask for a generic calculation.

ESG factors are increasingly linked to financial performance. Companies with strong ESG scores often enjoy lower cost of capital, better operational efficiency and reduced regulatory risk. Analysts incorporate ESG into discounted cash‑flow models by adjusting the discount rate or terminal growth assumptions.

Step‑wise integration: (1) Collect ESG data, (2) Score each pillar, (3) Apply weighting to obtain an overall ESG score, (4) Translate the score into a risk premium adjustment, and (5) Document the impact on valuation. The NISM exam may present a scenario requiring one or more of these steps.

Common mistake: treating ESG as a binary "yes/no" filter. The exam expects a nuanced approach where the magnitude of ESG performance influences the quantitative adjustment.

Rating agencies such as MSCI, Sustainalytics and India Ratings use proprietary models, but the underlying principle is a weighted aggregation of pillar scores. Each pillar receives a weight (e.g., 40% Environmental, 30% Social, 30% Governance) based on sector relevance.

Analysts may also build a simple in‑house score: assign a numeric rating (0‑100) to each pillar, multiply by the pre‑determined weight, and sum the results. The final ESG score can be mapped to a letter grade (AAA, AA, A, etc.) for communication to clients.

For the exam, remember the generic weighted‑average formula and be ready to plug in given weights and pillar ratings.

SEBI has issued circulars mandating listed entities to disclose material ESG risks in their quarterly and annual reports. The disclosures must be consistent with the Business Responsibility and Sustainability Report (BRSR) format introduced in FY 2022‑23.

Key requirements include reporting on carbon emissions, water usage, employee health & safety, board composition and anti‑bribery policies. Non‑compliance can attract penalties and affect a company’s listing status.

For the exam, remember that ESG disclosure is now a statutory obligation for listed companies in India, and analysts are expected to verify the completeness of these disclosures.
