ESG Reporting and Assurance: High-Growth Frontier for Indian CAs
Indian corporates are undergoing a structural shift: environmental and social performance can no longer be showcased through glossy sustainability brochures alone. Regulators, investors, and lenders now demand hard numbers—supported by proper systems, controls, and independent assurance.
For the assessee community of CAs—students, fresh members, and experienced professionals—this change has opened up a substantial new practice domain: ESG reporting and ESG assurance.
This article explains, in plain language:
- What ESG and ESG reporting actually involve
- Why recent regulatory and policy changes in India make ESG critical for CAs
- How existing CA skills map directly to ESG assignments
- Practical pathways to enter this space, for both practice and industry roles
- The business potential in large companies as well as MSMEs
Understanding ESG and ESG Reporting
What does ESG cover?
ESG stands for Environmental, Social, and Governance – three broad pillars used to evaluate how responsibly an enterprise operates beyond financial performance.
Environmental:
- Greenhouse gas emissions
- Energy usage and energy mix
- Water consumption and water stress
- Waste generation and disposal
- Pollution and resource efficiency
Social:
- Employee health, safety, and welfare
- Diversity, equity, and inclusion
- Labour conditions in own operations and supply chain
- Community impact and development initiatives
- Human rights and grievance redressal
Governance:
- Board structure and independence
- Board and management diversity
- Anti-bribery and anti-corruption mechanisms
- Executive remuneration practices
- Transparency, disclosures, and stakeholder engagement
ESG reporting is the structured disclosure of data, policies, and outcomes related to these three pillars. Initially, this was mostly voluntary and narrative-heavy. Today, especially for listed entities, it has evolved into:
- Quantitative indicators
- Standardised formats
- Year-on-year comparability
- External assurance requirements
This transformation has created a professional space that strongly resembles statutory financial reporting, but for non-financial information.
Why ESG Suddenly Matters So Much in India
SEBI’s BRSR and BRSR Core: The big regulatory trigger
The Securities and Exchange Board of India introduced the Business Responsibility and Sustainability Report (BRSR) for listed entities. Key milestones:
- BRSR is now mandatory from FY 2022–23 for the top 1,000 listed companies by market capitalisation.
- In addition, BRSR Core assurance has been introduced.
- From FY 2023–24, reasonable assurance on BRSR Core is compulsory for the top 150 listed companies.
- The assurance requirement will gradually expand until it covers all top 1,000 listed companies by FY 2026–27.
Note
BRSR Core is a focused subset of ESG metrics that must be subjected to reasonable assurance by an independent assurance provider.
This single development has created a new assurance market. Each covered company must:
- Set up ESG data systems
- Implement internal controls around ESG metrics
- Obtain independent ESG assurance
CAs, with their long-standing audit and assurance credentials, are natural contenders to provide this service.
India’s climate commitments and policy direction
India has committed to a Net-Zero target by 2070, with interim goals such as:
- Achieving 50% non-fossil fuel-based power capacity by 2030
- Reducing the emissions intensity of GDP by 45%
To align with these national targets, corporates must:
- Measure their emissions
- Track resource consumption
- Plan decarbonisation and efficiency measures
All of this requires robust measurement, documentation, and verification—areas where CAs can play a central role through carbon accounting, assurance on climate-related disclosures, and advisory on green incentives and carbon-related levies.
Explicit push from the Finance Minister
The Finance Minister Nirmala Sitharaman has publicly encouraged Indian CAs to build capabilities in:
- ESG reporting
- Carbon accounting
- CSR-related audits
This is more than a policy signal—it is an invitation for the profession to claim leadership in the ESG assurance ecosystem, both domestically and globally.
How ESG Builds on the Traditional CA Role
From financial statements to “sustainability statements”
Conventional CA practice focuses on:
- Financial audits
- Income Tax Act 1961 and GST compliance
- Company law compliance and statutory filings
- Internal financial controls and risk review
ESG work supplements—not replaces—these services by adding a non-financial layer of reporting and assurance. The foundational skills are the same.
