BRSR Core: What Indian Companies Need to Know About ESG Disclosures

Environmental, Social, and Governance (ESG) performance has become an increasingly important part of corporate reporting in India. Investors, regulators, customers, employees, and other stakeholders want greater visibility into how businesses manage environmental responsibilities, social practices, and corporate governance.

For listed companies, sustainability reporting is no longer limited to broad statements about responsible business practices. Companies are expected to provide structured information that allows stakeholders to understand their performance through relevant and measurable indicators.

This shift has made ESG disclosures an important part of corporate transparency and reporting. Understanding the requirements, data points, assurance expectations, and reporting processes can help companies prepare more effectively for their sustainability reporting responsibilities.

What Is BRSR Core and Why Does It Matter?

BRSR Core is a focused set of key performance indicators within India's Business Responsibility and Sustainability Reporting framework. SEBI introduced it to improve the reliability and credibility of important ESG information disclosed by listed entities. The framework focuses on selected critical ESG metrics for which reasonable assurance requirements apply according to the prescribed applicability timeline.

For companies navigating these requirements, professional ESG and BRSR advisory services in Thane, Mumbai can provide support in understanding applicable requirements, identifying relevant data points, establishing reporting processes, and preparing for assurance.

Rather than treating ESG reporting as an annual documentation exercise, businesses should view the process as part of their broader sustainability and governance strategy.

How BRSR Core Fits Into the BRSR Reporting Framework

The BRSR Reporting Framework provides a structured approach for listed companies to communicate their performance across environmental, social, and governance areas.

BRSR Core sits within this broader reporting ecosystem and focuses on a selected group of important performance indicators. The objective is to make key ESG information more consistent, comparable, and credible.

SEBI's original glide path introduced assurance requirements progressively, beginning with the top 150 listed entities in FY 2023–24 and expanding to the top 1,000 listed entities by FY 2026–27. Subsequent regulatory developments have refined aspects of the framework, so companies should refer to the latest applicable SEBI requirements when planning their reporting.

What Areas Does BRSR Core Cover?

The framework focuses on measurable ESG indicators rather than general sustainability statements. These indicators help stakeholders understand how an organization is performing in areas that can have a significant environmental, social, or governance impact.

Depending on the applicable reporting requirements, companies may need to organize and validate information relating to areas such as:

Environmental Performance

Environmental metrics can provide insight into how a company manages its environmental footprint.

Relevant areas may include:

• Greenhouse gas emissions

• Energy consumption

• Water management

• Waste generated and managed

• Resource utilization

• Environmental impact

Reliable environmental data requires consistent measurement processes across relevant business operations.

Social Performance

Social indicators provide insight into how an organization manages its workforce and broader social responsibilities.

Potential areas include:

• Employee well-being

• Gender diversity

• Employee health and safety

• Training and development

• Social impact

• Responsible business practices

Organizations need appropriate systems to collect, verify, and consolidate this information.

Governance and Business Responsibility

Governance-related disclosures help stakeholders understand how companies manage ethical business practices, accountability, and responsible decision-making.

These areas may include:

• Business ethics

• Governance mechanisms

• Responsible conduct

• Risk management

• Grievance mechanisms

• Corporate accountability

Why Accurate ESG Disclosures Matter

The quality of ESG information is becoming increasingly important. Inaccurate, inconsistent, or unsupported information can reduce stakeholder confidence and create challenges during reporting and assurance processes.

Well-managed ESG disclosures can help companies:

• Improve transparency

• Demonstrate accountability

• Identify sustainability risks

• Track ESG performance

• Support informed decision-making

• Improve stakeholder confidence

Companies should therefore establish processes that allow ESG information to be collected consistently throughout the reporting period rather than attempting to compile everything at the end of the year.

ESG Disclosure Examples Companies Should Understand

Understanding practical ESG disclosure examples can make the reporting process easier for internal teams.

For example, an organization may disclose information related to:

• Energy consumption and efficiency

• Scope 1 and Scope 2 emissions

• Water consumption

• Waste management

• Employee diversity

• Workplace safety

• Employee training

• Community initiatives

• Governance practices

The exact information required will depend on the applicable reporting requirements and the company's circumstances. Companies should avoid treating examples as a substitute for reviewing the latest regulatory requirements.

Building an Effective BRSR Core Reporting Process

Preparing for ESG reporting requires coordination between multiple departments. Sustainability teams may need information from finance, human resources, operations, procurement, legal, compliance, and other functions.

A structured process can include the following steps:

1. Identify Applicable Requirements

Companies should first determine which BRSR and BRSR Core requirements apply to them based on their regulatory status and reporting period.

2. Map ESG Data Sources

Identify where the required information is generated and which teams are responsible for maintaining it.

3. Establish Data Collection Processes

Create standardized procedures for collecting ESG information across departments and business locations.

4. Validate the Information

Data should be reviewed for completeness, consistency, and supporting documentation before it is included in reporting.

5. Prepare for Assurance

Where reasonable assurance is applicable, organizations should maintain appropriate evidence and internal controls to support reported information.

6. Identify Reporting Gaps

A gap assessment can help companies identify missing data, inconsistent measurement methods, or weaknesses in internal processes.

Common Challenges Companies Face With BRSR Core

Despite having sustainability initiatives in place, companies may face difficulties when converting operational information into structured ESG data.

Common challenges include:

• Inconsistent data collection

• Lack of clear ownership

• Limited historical ESG data

• Different measurement methodologies

• Inadequate documentation

• Difficulty coordinating multiple departments

• Limited understanding of assurance expectations

Addressing these issues early can make the reporting process more efficient and reduce last-minute challenges.

How Companies Can Prepare for Better ESG Reporting

Organizations can improve their preparedness by integrating ESG data management into regular business processes.

Some practical steps include:

Define Internal Responsibilities

Assign clear ownership for individual ESG metrics so that teams understand what information they need to provide.

Maintain Supporting Documentation

Keep records, calculations, policies, invoices, operational data, and other evidence that support reported metrics.

Standardize Measurement Methods

Using consistent methodologies can make year-on-year comparison and internal review easier.

Conduct Periodic Reviews

Regular internal reviews can identify errors or gaps before the final reporting process.

Integrate ESG Into Business Strategy

ESG reporting becomes more meaningful when sustainability objectives are connected to operational and strategic decision-making.

Why ESG Reporting Should Be Viewed as More Than Compliance

While regulatory reporting is an important driver, ESG information can also provide valuable insights into business performance and risk.

For example, environmental data can highlight opportunities to improve resource efficiency. Workforce information can help organizations identify people-related risks and opportunities. Governance data can support stronger accountability and decision-making.

Therefore, companies that integrate ESG reporting into their broader business strategy can use the process not only to meet reporting expectations but also to identify areas for operational improvement.
