The regulatory reality

Why BRSR and carbon reporting is no longer optional

SEBI has made sustainability disclosure a listing requirement, not a CSR gesture. The companies that treat it as an afterthought are the ones scrambling every March.

The Mandate

BRSR is compulsory

India's top 1,000 listed companies must file a Business Responsibility & Sustainability Report with every annual report. It is a listing obligation under SEBI's LODR regulations.

The Scrutiny

Auditors will verify it

BRSR Core disclosures must be independently assured. Numbers pulled together in spreadsheets the week before filing rarely survive third-party scrutiny.

The Cost

Non-compliance is expensive

Late or missing filings attract penalties of ₹2,000 per day, exchange notices, and questions from institutional investors that are far costlier than the fine.

The Upside

Carbon measurement pays back

India's Carbon Credit Trading Scheme turns verified emission reductions into tradeable CCTS credits. You can't reduce — or earn from — what you never measured.

BRSR Core assurance timeline — the deadlines are already here

FY 2022-23
BRSR mandatory for top 1,000 listed companies
FY 2023-24
BRSR Core assurance begins for top 150
FY 2024-25
Assurance extends to top 250
FY 2025-26

Companies using CarbonLens BRSR software build their emissions baseline early — filing in days, not months — and walk into assurance reviews with an audit trail instead of a shoebox of invoices.

Security-first architecture

Your ESG and carbon data is safe with us

CarbonLens is built with security and compliance at every layer — from how passwords are stored to how your carbon accounting data flows through the system.

Bank-Grade Credential Protection

Passwords are protected with industry-standard one-way cryptography. Plain-text passwords are never stored anywhere in our systems.

Cryptographically Verified Sessions

Every request to the carbon accounting platform is verified cryptographically before any ESG data is returned. Sessions cannot be forged, replayed, or hijacked.

Role-Based Access Control

Access is checked on every action based on the user's role. Users can only ever see carbon and ESG data belonging to their own organisation.

Hardened Against Injection Attacks

All database access goes through parameterised layers, so user input can never alter the structure of a query — a structural defence, not a case-by-case one.

Strict Input Validation

Every piece of incoming data is validated against a strict schema before it is processed. Malformed or malicious payloads are rejected at the API layer.

Server-Only Data Access

Your carbon accounting and ESG data lives strictly server-side and is never sent to or accessible from the browser.

All carbon accounting and ESG data is stored in encrypted PostgreSQL databases hosted on AWS infrastructure in India. CarbonLens complies with the DPDP Act 2023 — your data stays in India.

Frequently asked questions about BRSR software and carbon accounting

What is BRSR Core and who needs to comply?

BRSR Core (Business Responsibility and Sustainability Reporting Core) is a SEBI-mandated ESG disclosure framework for listed companies in India. Third-party assurance is mandatory for the top 500 listed companies from FY 2025-26, and for the top 1,000 from FY 2026-27. CarbonLens is India's leading BRSR software that automates this compliance.

What is Scope 1, Scope 2, and Scope 3 emissions?

Scope 1 are direct GHG emissions from owned or controlled sources (e.g., fuel combustion, company vehicles). Scope 2 are indirect emissions from purchased electricity, steam, or heat. Scope 3 covers all other indirect emissions across a company's value chain, including 15 categories defined by the GHG Protocol — from business travel to purchased goods. CarbonLens tracks all three scopes with India-specific emission factors from CEA, BEE, and MoEFCC.

How does CarbonLens BRSR software help with BRSR Core compliance?

CarbonLens automates BRSR Core compliance by tracking Scope 1, 2 & 3 GHG emissions using India-specific emission factors. It generates SEBI-compliant BRSR Core reports with one click, auto-populating all 9 principles from your emission data, ready for third-party assurance. The audit trail and role-based access ensure your BRSR reporting is assurance-ready from day one.

What is the Carbon Credit Trading Scheme (CCTS) in India?

India's Carbon Credit Trading Scheme (CCTS) is a market-based mechanism under the Energy Conservation (Amendment) Act 2022, administered by the Bureau of Energy Efficiency (BEE) under MoEFCC. It enables companies to trade carbon credits for meeting GHG emission intensity targets. CarbonLens is the only BRSR and carbon accounting software that integrates CCTS registration, tracking, and portfolio management.

How much does CarbonLens BRSR and carbon accounting software cost?

CarbonLens offers three annual plans in INR: Starter at ₹2,49,000/year (Scope 1 & 2, BRSR Core, up to 3 users), Growth at ₹4,99,000/year (full Scope 3, Tally ERP integration, Bill OCR, CCTS, up to 10 users), and Enterprise with custom pricing for CA firms and multi-entity groups. All plans include a 14-day free trial.

Does CarbonLens integrate with Tally ERP for carbon accounting?

Yes. CarbonLens connects to your Tally ERP instance and automatically converts fuel and electricity ledger entries into verified GHG emission records, eliminating manual data re-entry for carbon accounting. This is the only Tally ESG integration available in India's carbon accounting software market.

What is the difference between BRSR and ESG reporting?

BRSR (Business Responsibility and Sustainability Reporting) is India's specific SEBI-mandated ESG disclosure framework for listed companies. ESG (Environmental, Social, and Governance) reporting is the broader global practice of disclosing sustainability performance. BRSR is India's localized implementation of ESG reporting requirements. CarbonLens covers both BRSR compliance and broader ESG data management.

Which industries does CarbonLens carbon accounting software serve?

CarbonLens serves all SEBI-listed companies across manufacturing, pharmaceuticals, automotive, cement, steel, chemicals, FMCG, textiles, energy, and infrastructure sectors. Any company in India's top 1,000 listed companies that needs BRSR compliance, carbon accounting, or ESG reporting can use CarbonLens.

Is CarbonLens a GHG Protocol compliant carbon accounting software?

Yes. CarbonLens follows the GHG Protocol Corporate Standard for Scope 1, 2, and 3 accounting. It uses India-specific emission factors from the Central Electricity Authority (CEA), Bureau of Energy Efficiency (BEE), and Ministry of Environment, Forest and Climate Change (MoEFCC), ensuring your GHG inventory is both globally standards-compliant and India-relevant.

How does Bill OCR work in CarbonLens?

CarbonLens's Bill OCR feature lets you upload electricity bills, fuel bills, and utility bills directly to the platform. The OCR engine automatically extracts consumption quantities, billing periods, and fuel types, creating verified emission entries without manual data entry — saving hours of work per reporting cycle.

BRSR Core assurance is mandatory. Is your carbon accounting ready?

Top 500 listed companies must have third-party assured BRSR Core from FY 2025-26. Start with India's best BRSR software today. Non-compliance: ₹2,000 per day.
