Pre-Engagement Checklist for GHG Accounting
Before starting, align internal stakeholders and define the reporting objective for your emissions inventory. Confirm the organizational boundaries (operational control vs. equity share), map activities and facilities, and list available primary data sources such as fuel receipts, electricity bills, steam purchases, refrigerant logs, and transport records. Assign an GHG Scope 1, 2, and 3 calculation services accountable owner for data quality and review. Validate whether you need assurance-ready documentation, then set a clear scope for what will be calculated versus what will be estimated. This step prevents rework and supports ESG compliance and due diligence India expectations.
Data Collection and Quality Controls
Gather activity data systematically and standardize units to avoid calculation errors. Use a traceable approach: keep evidence for each dataset, document assumptions, and record conversion factors. For Scope 1, confirm combustion sources and process emissions where applicable; for Scope 2, capture purchased electricity and any renewable attributes; for Scope 3, collect ESG compliance and due diligence India supplier, logistics, waste, and business-travel inputs relevant to your value chain. Apply data validation checks such as completeness screening, outlier detection, and consistency across invoices and logs. Maintain a version-controlled audit trail so results remain defensible during internal reviews and external scrutiny.
Calculation Methodology, Verification, and Reporting Outputs
Select calculation tools and emission factors that fit your sector and reporting requirements, then document the methodology end-to-end. Ensure Scope 1 and 2 calculations are aligned with your energy accounting approach, and that Scope 3 categories follow a structured screening process to identify material categories. Perform gap analysis to determine where primary data is missing, then quantify uncertainty for estimates. Produce clear outputs: emission totals by scope, breakdowns by category and facility, and a reconciliation summary linking activity data to emission results. If assurance is required, prepare evidence packs and verification-ready documentation. This supports reliable for governance and decision-making.
Conclusion
A robust checklist reduces risk, improves transparency, and strengthens the credibility of your emissions inventory. By defining boundaries, enforcing data quality controls, and delivering verification-ready calculation outputs, companies can move from estimates to measurable sustainability performance.
