  • How ESG Ratings Are Calculated in India: CRISIL, MSCI & CDP – and How We Help You Score Better

A mid-sized electronics manufacturer recently faced a sharp drop in its ESG rating from “A” to “BBB” within one reporting cycle. The issue was not financial performance or governance failure. The real reason was non-compliance. Their EPR returns were filed late, waste traceability records were incomplete, and CPCB portal submissions had inconsistencies.

Within 6 months, this resulted in investor queries, delayed approvals from authorities, and increased scrutiny from SPCB. The company had to spend additional resources to correct compliance gaps and regain its ESG position.

This is becoming a frequent situation in India where ESG ratings are no longer driven by sustainability reports alone. They are directly linked to regulatory compliance and real operational data.

ESG Rating

Introduction: Why ESG Ratings in India Are Now Compliance Driven

ESG ratings in India have moved from voluntary disclosures to structured, compliance-driven evaluation systems. Regulatory frameworks such as SEBI BRSR, CPCB EPR portals, and MoEFCC environmental rules now play a central role in determining ESG scores.

For most manufacturing and import-based businesses, ESG performance is now evaluated through measurable compliance metrics. Companies are expected to demonstrate real environmental performance, not just policy declarations.

The urgency has increased significantly due to regulatory and market factors:

  • Over 1000 listed companies are now required to file BRSR reports annually
  • ESG-based investment decisions have increased by more than 40 percent in the last 3 years
  • Non-compliance can lead to operational delays, penalties, and investor risk flags

Businesses that fail to align ESG with compliance frameworks often face score downgrades, while compliant companies gain a competitive advantage in funding and approvals.

How ESG Ratings Are Actually Calculated in India

ESG ratings are calculated using a structured scoring model across three pillars: Environmental, Social, and Governance. Each pillar is evaluated using quantitative and qualitative data, but in India, environmental compliance carries the highest weightage.

Environmental Pillar – 40 percent to 60 percent Weightage

The environmental component is the most critical for industries such as manufacturing, electronics, automotive, and chemicals. It evaluates how effectively a company manages emissions, waste, and resource consumption.

In India, this pillar is heavily influenced by CPCB regulations and waste management rules. ESG agencies assess whether companies are meeting their legal obligations under frameworks like E-Waste Rules 2022, Battery Waste Rules, Plastic Waste Management Rules, and ELV Rules 2025.

Companies are expected to demonstrate actual recycling performance, emission reduction, and compliance filing accuracy. Data is often verified through portal submissions and audit records.

Key evaluation parameters include:

  • Percentage of waste recycled versus total waste generated
  • EPR target achievement such as 8 percent, 13 percent, and 18 percent across financial periods
  • Reduction in carbon emissions and energy intensity
  • Compliance with CPCB and SPCB authorizations

Social Pillar – 20 percent to 30 percent Weightage

The social pillar evaluates how a company manages its workforce, supply chain, and community impact. While it has relatively lower weightage than environmental factors, it still plays an important role in ESG scoring.

Companies are assessed on employee safety, working conditions, and social responsibility initiatives. In industries with high labor intensity, this pillar becomes more significant.

Important factors include:

  • Workplace safety compliance and accident frequency rates
  • Employee welfare measures and retention rates
  • CSR spending and community engagement
  • Supply chain labor practices

Governance Pillar – 20 percent to 30 percent Weightage

Governance focuses on how well a company manages compliance, transparency, and reporting systems. In India, governance is closely linked with regulatory filings and ESG disclosures.

Companies with strong governance frameworks tend to have consistent ESG scores because their reporting systems are reliable and audit-ready.

Key parameters include:

  • Accuracy and consistency of regulatory filings
  • Board structure and independence
  • ESG disclosure quality under BRSR
  • Internal compliance monitoring systems

Key Observations from ESG Calculation Models

A detailed analysis of ESG rating methodologies shows that environmental compliance contributes the highest impact on scoring, especially in regulated industries.

  • Environmental compliance can influence up to 60 percent of total ESG score
  • Companies with consistent CPCB filings show 20 percent higher ESG stability
  • ESG downgrades are often linked to compliance failures rather than operational performance

ESG Rating Agencies in India: CRISIL vs MSCI vs CDP

CRISIL ESG Rating – Compliance Focused Indian Model

CRISIL ESG ratings are widely used in India and focus heavily on regulatory compliance and risk exposure. The scoring model evaluates how well companies align with Indian environmental laws and compliance frameworks.

CRISIL assesses real compliance performance, including CPCB registrations, EPR filings, and environmental approvals. Companies with poor compliance records are assigned higher risk scores.

Key evaluation areas:

  • Compliance with CPCB and SPCB regulations
  • Waste management and recycling systems
  • Environmental penalties or notices
  • Alignment with SEBI BRSR requirements

MSCI ESG Rating – Global Risk Based Model

MSCI ESG ratings are used by global investors and focus on risk exposure rather than detailed regulatory compliance. The rating scale ranges from AAA to CCC.

While MSCI considers environmental performance, it does not deeply integrate India-specific compliance frameworks such as CPCB portal filings or EPR obligations.

Key evaluation areas:

  • Carbon emissions and energy usage
  • Industry-specific ESG risks
  • Supply chain sustainability
  • Global disclosure standards

CDP Scoring – Climate Disclosure Driven Model

CDP focuses specifically on climate-related disclosures and environmental transparency. Companies are scored from A to D based on their climate performance and reporting quality.

This model is particularly relevant for export-oriented companies and businesses with international stakeholders.

Key evaluation areas:

  • Carbon footprint disclosure
  • Climate risk management
  • Emission reduction strategies
  • Transparency in reporting

Key Differences Between ESG Rating Agencies

Each agency uses a different approach, which leads to variation in ESG scores.

  • CRISIL focuses on compliance and regulatory risk
  • MSCI evaluates global ESG risk exposure
  • CDP focuses on climate disclosure and transparency

For Indian companies, compliance alignment plays a decisive role in achieving consistent ESG scores across all agencies.

Regulatory Impact on ESG Scoring

Regulation Requirement Deadline Applicable To Risk
E-Waste Rules 2022 EPR registration and recycling targets Ongoing Electronics sector Registration rejection
Battery Waste Rules 2025 EPR registration and labeling Immediate Battery producers Portal suspension
PWM Amendment 2025 Barcode traceability requirement 01 July 2025 Plastic users SPCB action
ELV Rules 2025 Recycling targets 8 percent to 18 percent Financial year based Automobile sector Environmental compensation

These regulations directly influence ESG scores because agencies evaluate whether companies are meeting their legal obligations.

Key insights:

  • Non-compliance can lead to ESG score reduction of 10 percent to 25 percent
  • Regulatory violations are flagged during ESG audits
  • Compliance data from CPCB portals is increasingly used in ESG assessments

ESG Compliance Workflow in India

Step Authority Timeline Documents Risk
Registration CPCB or SPCB 30 to 60 days GST, PAN, CIN, IEC Rejection
Quarterly Filing CPCB Every quarter Waste data Suspension
Annual Return CPCB Once per year Awareness data Penalty
Certificate Purchase Recycler or RVSF Continuous EPR certificates Target failure

A structured compliance workflow is essential for maintaining ESG performance. Companies must ensure that filings are timely, accurate, and aligned with regulatory requirements.

Key observations:

  • Delayed filings can immediately impact ESG scoring
  • Annual returns require complete disclosure of environmental activities
  • Inconsistent data reporting increases audit risk

EPR Compliance – The Backbone of ESG Scores

Extended Producer Responsibility is one of the most important components influencing ESG ratings in India. It directly measures how companies manage post-consumer waste and recycling obligations.

EPR compliance requires companies to register on CPCB portals, meet recycling targets, and submit regular returns. The entire process is data-driven and traceable.

How the mechanism works:

  • Producers introduce products into the market
  • Waste is collected and processed by authorized recyclers
  • Recyclers generate EPR certificates based on processed quantity
  • Producers purchase these certificates to meet their obligations

Key compliance requirements:

  • Registration on CPCB portal with valid company documents
  • Quarterly and annual return filings
  • Meeting assigned recycling targets
  • Maintaining traceability of waste processing

Important documents required:

  • GST registration certificate
  • PAN and CIN details
  • IEC for importers
  • Waste generation and processing data

Compliance Risks and ESG Impact

Failure to comply with environmental regulations does not only result in penalties. It directly affects ESG ratings, investor perception, and business operations.

Major risks include:

  • Rejection of CPCB registration applications
  • Suspension of portal access
  • Environmental compensation charges
  • SPCB refusal for approvals
  • Import and export restrictions
  • Production delays or shutdowns

Legal exposure:

  • Liability under Section 15 of Environment Protection Act, 1986
  • Financial penalties that can extend into lakhs or crores depending on violation

Companies that ignore compliance often face long-term damage to both ESG ratings and operational stability.
