ISO 14064 is the international standard for greenhouse gas quantification, reporting, and verification. With CCTS compliance requiring audit-grade GHG data, and CBAM demanding installation-level embedded carbon calculations, ISO 14064 alignment is becoming essential for Indian industry — not optional.
ISO 14064: The Three Parts
ISO 14064-1 specifies requirements for designing, developing, managing, and reporting organisation-level or facility-level GHG inventories. This is where most Indian companies start.
ISO 14064-2 covers project-level GHG emission reductions and removal enhancements — relevant for carbon credit project development under CCTS or voluntary markets.
ISO 14064-3 provides requirements for verification and validation of GHG assertions — the standard that accredited verifiers apply when auditing your GHG data.
Why Indian Companies Need ISO 14064 Now
- CCTS Compliance: BEE’s MRV requirements align with ISO 14064 principles. Companies with ISO 14064-aligned systems will have smoother compliance.
- CBAM Reporting: EU importers need embedded carbon data calculated using recognised methodologies. ISO 14064 alignment provides credibility.
- BRSR Principle 6: SEBI’s sustainability reporting requires GHG disclosure. ISO 14064 provides the rigour behind the numbers.
- Investor Expectations: ESG-conscious investors and lenders increasingly require ISO-aligned GHG data for climate risk assessment.
Key Implementation Steps
Boundary Definition
Choose between equity share and operational control approaches. For most Indian companies, operational control is more practical. Define which facilities, processes, and emission sources are included.
Source Identification
Catalogue all GHG sources: stationary combustion (boilers, furnaces, DG sets), mobile combustion (company vehicles), process emissions (chemical reactions), fugitive emissions (refrigerant leaks, coal seam methane), and purchased energy (grid electricity, steam).
India-Specific Emission Factors
Use CEA’s published grid emission factor (CO2 baseline database, updated annually). For fuel combustion, use IPCC default factors or India-specific factors from MoEFCC. For process emissions, use sector-specific factors from BEE or industry associations.
Uncertainty Assessment
ISO 14064 requires documenting uncertainty in your GHG inventory. Quantify uncertainty from measurement equipment accuracy, emission factor variability, and activity data gaps. This is often the most overlooked step in Indian implementations.
