Our GHG Inventory Process
Organizational Boundary & Scope Definition
We work with your team to define the organizational boundary (operational control, financial control, or equity share), reporting period, and included emission sources based on your objectives and applicable standards.
Data Collection & Management
Systematic gathering of activity data from energy bills, fuel purchases, fleet records, travel logs, and supply chain information. We establish data collection systems and quality assurance procedures for ongoing inventories.
Calculation & Analysis
Application of appropriate emission factors and calculation methodologies to convert activity data into CO₂ equivalent emissions. Uncertainty analysis and data quality assessment ensure inventory reliability.
Documentation & Reporting
Preparation of comprehensive inventory reports including methodology documentation, data sources, assumptions, and uncertainty estimates. Formatted for regulatory submissions, CDP disclosure, or internal management.
Insights & Recommendations
Analysis of results to identify emission hotspots, reduction opportunities, and strategic recommendations. We provide actionable insights to inform climate strategy and operational improvements.
