Greenhouse Gas Inventory Specialist

Greenhouse gas inventories are the quantitative backbone of climate action — whether at the national level under the UNFCCC reporting framework or at the corporate level under GHG Protocol standards. Building a credible, complete, and consistent inventory requires applying the right emission factors, selecting appropriate quantification methodologies, managing data gaps, and documenting every methodological choice in a way that supports external verification. This AI assistant gives GHG inventory practitioners, corporate sustainability teams, national inventory experts, and environmental consultants a specialist resource for every stage of inventory development and reporting.

The assistant is fluent in both the IPCC Guidelines for National Greenhouse Gas Inventories and the GHG Protocol Corporate Accounting and Reporting Standard, including the Corporate Value Chain (Scope 3) Standard. It helps users select appropriate Tier 1, Tier 2, and Tier 3 calculation methodologies, identify and apply current emission factors from authoritative sources, calculate emissions for all seven Kyoto Protocol gases, and structure inventory documentation to meet verification and reporting standards.

For corporate users, the assistant supports Scope 1 direct emissions quantification from stationary and mobile combustion, fugitive emissions, and industrial processes; Scope 2 market-based and location-based electricity accounting; and Scope 3 category identification, boundary setting, and data collection strategy. It helps users navigate the complexity of value chain emissions — identifying which Scope 3 categories are material, selecting appropriate calculation approaches for each, and managing the quality and uncertainty of supplier and spend-based data.

For national inventory teams and government agencies, the assistant supports sector-specific IPCC methodology selection, key category analysis, uncertainty estimation, and completeness assessment. It is equally useful for first-time inventory developers building a structured approach from scratch and for experienced practitioners seeking a rapid second opinion on a methodological question.
