Sustainability Reporting: Step-by-Step Filing Process for Businesses

Step 1: Identify Applicable Sustainability Framework

Determine which framework applies to your organization:

  • Indian listed entities → BRSR (SEBI)
  • Global stakeholders → GRI / ESG / TCFD
  • Industry-specific needs → SASB

Clear framework selection ensures accurate disclosures.


Step 2: Define Scope and Reporting Boundaries

Decide:

  • Reporting period (financial year)
  • Entities/subsidiaries covered
  • Geographic scope
  • Operational boundaries

This avoids inconsistencies and data gaps.


Step 3: Form an Internal Sustainability/ESG Team

Create a cross-functional team including:

  • Finance
  • HR
  • Operations
  • Legal & Compliance
  • Environment, Health & Safety (EHS)

Assign clear roles for data ownership and validation.


Step 4: Identify Material ESG Topics

Conduct a materiality assessment to identify key ESG issues such as:

  • Energy usage & emissions
  • Water & waste management
  • Employee welfare & diversity
  • Ethics, governance & compliance
  • Community & social impact

Material topics are mandatory disclosures in most frameworks.


Step 5: Collect ESG Data

Gather quantitative and qualitative data, including:

Environmental Data

  • Energy consumption
  • Carbon emissions
  • Water usage
  • Waste generation

Social Data

  • Employee strength & diversity
  • Health & safety metrics
  • Training & development
  • CSR activities

Governance Data

  • Board composition
  • Ethics policies
  • Risk management
  • Compliance records

Ensure data accuracy and documentation.


Step 6: Validate and Verify Data

  • Cross-check data internally
  • Align metrics with reporting standards
  • Conduct internal audits or third-party assurance (recommended)

Verification enhances report credibility.


Step 7: Prepare the Sustainability Report

Draft the report including:

  • Company overview
  • ESG strategy & governance
  • Framework-specific disclosures
  • Performance metrics & targets
  • Policies and initiatives

For India, follow SEBI-prescribed BRSR format.


Step 8: Obtain Board Approval

Before filing:

  • Present the report to senior management
  • Obtain Board of Directors’ approval
  • Document approvals in meeting minutes

This step is mandatory for listed companies.


Step 9: File / Publish the Sustainability Report

Depending on requirements:

  • Upload BRSR as part of Annual Report
  • File with stock exchanges (SEBI entities)
  • Publish on company website
  • Share with investors and stakeholders

Ensure timely submission to avoid penalties.


Step 10: Maintain Records & Continuous Improvement

Post-filing:

  • Retain supporting documents
  • Track ESG performance year-on-year
  • Improve disclosures and sustainability goals
  • Prepare for future audits or inspections

Penalties for Non-Compliance (India – BRSR)

  • Regulatory scrutiny by SEBI
  • Penalties under listing regulations
  • Reputational and investor trust impact

Benefits of Sustainability Reporting

  • Regulatory compliance
  • Improved investor confidence
  • Enhanced brand reputation
  • Better risk management
  • Access to ESG funding
  • Long-term business sustainability
