ESG reporting in India is the structured disclosure of a company's environmental, social and governance performance — emissions, energy and water use, waste, workforce and supply-chain practices, board oversight and business ethics. SEBI's Business Responsibility and Sustainability Report (BRSR) already makes it mandatory for the top 1,000 listed companies, with assurance being phased in for the largest ones. Beyond regulation, global customers, lenders and investors increasingly expect Indian companies to report under GRI, CSRD or ISSB-based standards, which is why ESG reporting skills are in rising demand across finance, manufacturing and consulting.

ESG reporting in accounting means handling sustainability data with the same discipline as financial data — defined metrics, internal controls, evidence trails and independent assurance. Frameworks such as IFRS S1 and IFRS S2 are designed to sit alongside IFRS financial statements, and under CSRD the sustainability statement becomes part of the management report with mandatory assurance. For accountants and auditors, this has created new work in ESG data validation, carbon accounting, internal controls and assurance readiness, since sustainability numbers now face the same scrutiny as revenue or expense figures.

Start with the fundamentals — what E, S and G actually cover — then go deep on one framework. In India, BRSR and GRI are the most practical starting points, while CSRD/ESRS and IFRS S1 & S2 matter if you work with global or EU-facing companies. Read two or three published BRSR or GRI reports of Indian listed companies line by line, practise a simple materiality assessment and a GHG inventory covering Scopes 1, 2 and 3, and reinforce this with a structured course, certification and mentor feedback. Employers value demonstrated hands-on work far more than certificates alone.

The working sequence is: (1) pick the framework based on regulation and audience — BRSR for listed Indian companies, GRI for voluntary global reporting, CSRD/ESRS for EU exposure; (2) run a materiality or double materiality assessment to prioritise topics; (3) define KPIs and calculation methodologies for each topic; (4) set up data collection with clear owners, controls and evidence trails; (5) build a GHG inventory for Scope 1, Scope 2 and material Scope 3 emissions; (6) draft disclosures with methodology notes and restatement policies; and (7) complete internal review and, where required, external assurance before publishing.

The most widely used are GRI (voluntary global reporting), IFRS S1 and S2 from the ISSB (investor-focused global baseline), CSRD with its ESRS (mandatory in the EU), SASB (industry-specific metrics, now under the ISSB), TCFD (climate-risk recommendations now embedded in ISSB standards), CDP (annual disclosure platform) and BRSR (mandatory in India). The core ESG reporting standards that define the actual metrics are the GRI Standards, the ESRS and IFRS S1 & S2. In practice, most companies prepare one set of disclosures and map it across several frameworks instead of reporting separately for each.

There is no single mandatory ESG reporting certification, so choose by goal. For climate risk and sustainability strategy roles, GARP's Sustainability and Climate Risk (SCR) Certificate and the CFA Institute's Certificate in ESG Investing are well recognised. For hands-on disclosure work, GRI certified training and CSRD/ESRS-focused programmes are more useful. When comparing ESG reporting courses, check whether they cover multiple frameworks (BRSR, GRI, CSRD/ESRS, IFRS S1 & S2), include real datasets and report-writing practice, and are taught by practitioners — that combination is what makes you job-ready.

Pick a lane first — ESG reporting, carbon accounting and net-zero planning, ESG ratings or research, sustainability consulting, or assurance — then build the basics: climate fundamentals, major frameworks (BRSR, GRI, CSRD, ISSB) and one recognised credential such as GARP SCR. Do practical projects you can show recruiters, like a mock BRSR report, a Scope 1–3 inventory or a materiality matrix, and rewrite your CV so existing experience in audit, finance, engineering or HSE is framed in ESG language. Entry roles include ESG analyst, sustainability associate and ESG reporting executive, and a mentor's review of your transition plan usually shortens the path considerably.

The meaning of Scope 3 emissions is simple: they are all the indirect greenhouse gas emissions that occur across a company's value chain — upstream with suppliers and downstream with customers — but outside its own operations and purchased energy. Scope 1 covers direct emissions from company-owned sources, Scope 2 covers purchased electricity, heat and steam, and Scope 3 is everything else, such as supplier manufacturing, business travel, employee commuting, logistics, waste and the use of sold products. For most organisations, Scope 3 is the largest share of the total carbon footprint, often above 70%, which is why it attracts the most attention.

The GHG Protocol divides Scope 3 into eight upstream and seven downstream categories: (1) purchased goods and services, (2) capital goods, (3) fuel- and energy-related activities, (4) upstream transportation and distribution, (5) waste generated in operations, (6) business travel, (7) employee commuting, (8) upstream leased assets, (9) downstream transportation and distribution, (10) processing of sold products, (11) use of sold products, (12) end-of-life treatment of sold products, (13) downstream leased assets, (14) franchises and (15) investments. Companies screen all 15 categories of Scope 3 emissions first and then report the ones that are material to their business.

Everyday examples of Scope 3 emissions include the manufacturing emissions behind purchased raw materials and components, flights and hotel stays for business travel, employee commuting, third-party trucks and ships moving finished goods, waste sent to landfill, and the emissions from using sold products — such as the fuel burned by vehicles a carmaker sells or the electricity consumed by appliances after purchase. Because these emissions sit outside the company's direct control and depend on suppliers and customers, they are the hardest to measure and the most frequently challenged by auditors and investors.

Calculations follow the GHG Protocol Corporate Value Chain (Scope 3) Standard: set boundaries, screen the 15 categories for materiality, then quantify. The two main methods are spend-based — multiplying procurement spend by industry-average emission factors, which is quick but coarse — and activity-based, which multiplies activity data such as litres of fuel, tonne-kilometres of freight, kilowatt-hours or hotel nights by published emission factors, with supplier-specific data being the most accurate. Most companies start spend-based to identify hotspots, then prioritise primary supplier data for the largest categories, documenting methods, factors and assumptions for audit.

Reduction starts with measurement, because hotspots decide strategy. Proven levers include supplier engagement and low-carbon procurement criteria, shifting to suppliers that disclose and cut their own emissions, logistics optimisation and modal shift, tighter travel policies with virtual-first meeting norms, product redesign for energy efficiency, durability and recyclability, renewable electricity requirements across the value chain, and circular approaches to materials and waste. Setting science-based targets (SBTi) anchors these actions in measurable milestones, and re-measuring Scope 3 annually shows whether emissions are genuinely falling or merely being re-estimated.

The Corporate Sustainability Reporting Directive (CSRD) is the European Union's sustainability reporting law, in force since January 2023, which replaced the older NFRD. It requires in-scope companies to report against the European Sustainability Reporting Standards (ESRS) using double materiality, obtain assurance over the sustainability statement, and file disclosures digitally as part of the management report. Although it is EU legislation, it matters in India — Indian companies with EU subsidiaries, EU parent groups or significant EU revenue can fall in scope, and many more face CSRD-linked data requests from European customers.

The core CSRD reporting requirements are: a double materiality assessment; disclosures under the ESRS covering climate, pollution, biodiversity, circular economy, social and governance topics; GHG reporting across Scopes 1, 2 and 3; the sustainability statement filed within the management report; limited assurance; and digital tagging of disclosures. The CSRD reporting thresholds decide who is covered — large EU companies exceeding at least two of three criteria (250+ employees, €40 million+ net turnover, €20 million+ balance sheet), listed EU SMEs, and non-EU groups with more than €150 million of EU turnover. Companies typically begin with a gap assessment against the ESRS, then build data, controls and documentation.

The CSRD reporting timeline is phased by company type. The first wave — large listed companies already covered by the NFRD — published their first reports in 2025 for financial year 2024. Other large EU companies, listed SMEs and finally non-EU parent companies follow in later waves, and the EU has pushed some of these back by two years through its stop-the-clock amendment while it simplifies the rules. Companies in Indian supply chains should track their EU customers' wave, because CSRD-linked data requests typically arrive at least a year before the customer's own reporting deadline.
