As India's ESG landscape matures, Scope 3 emissions — those generated across a company's entire value chain — are emerging as the most significant and complex category of greenhouse gas (GHG) reporting. For Indian businesses, understanding and managing Scope 3 is no longer optional; it is becoming a core investor, regulatory, and reputational requirement.
📌 Key fact: Scope 3 emissions typically represent 70–90% of a company's total carbon footprint, yet most Indian companies still report only Scope 1 and 2.
What Are Scope 3 Emissions?
The GHG Protocol categorises emissions into three scopes. Scope 1 covers direct emissions from owned or controlled sources. Scope 2 covers indirect emissions from purchased energy. Scope 3 encompasses all other indirect emissions that occur in a company's value chain — upstream and downstream.
The 15 categories of Scope 3 include:
- Purchased goods and services
- Capital goods
- Fuel and energy-related activities
- Upstream and downstream transportation
- Waste generated in operations
- Business travel and employee commuting
- Use of sold products
- End-of-life treatment of sold products
- Investments and leased assets
Why Is Scope 3 Now Critical for Indian Companies?
Global investors and multinational supply chain partners are increasingly requiring Indian suppliers to disclose Scope 3 data. SEBI's BRSR framework, while currently focused on Scope 1 and 2, is expected to include mandatory Scope 3 reporting for the top 250 listed companies by FY 2026-27.
Investor Pressure
Foreign institutional investors (FIIs) aligned with Science Based Targets initiative (SBTi) commitments are pushing Indian portfolio companies to set supply chain emission reduction targets. Companies without credible Scope 3 data risk being excluded from ESG indices.
Export Market Requirements
The European Union's Carbon Border Adjustment Mechanism (CBAM) directly impacts Indian exporters of steel, cement, aluminium, and fertilisers. Businesses must be able to demonstrate the embedded carbon in their products — which requires comprehensive Scope 3 accounting.
How to Start Measuring Scope 3
- Identify the most material Scope 3 categories for your industry
- Collect activity data from suppliers and logistics partners
- Apply appropriate emission factors (IPCC, GHG Protocol databases)
- Set a base year and establish reduction targets
- Engage a third-party verifier for credibility
💡 BEC Tip: Start with a high-level screening assessment to identify your top 3 material Scope 3 categories — this is more actionable than trying to measure all 15 categories at once.
Conclusion
Scope 3 emissions reporting is transitioning from a voluntary best practice to a business necessity for Indian companies with global ambitions. Investing in supply chain data collection infrastructure and GHG accounting capability now will provide a significant competitive advantage in the coming years.
