Scope3Trace: Evidence-Based Identification and Extraction of Scope 3 GHG Emissions from Sustainability Reports
Quick Answer
Scope3Trace is an evidence-grounded framework for extracting Scope 3 GHG emissions from ESG reports, overcoming challenges of sparse disclosures and heterogeneous formats.
Quick Take
It utilizes a hybrid rule- approach for reliable extraction and verification, achieving high accuracy in identifying organization-level emissions. The framework also introduces a multimodal dataset for enhanced analysis.
Key Points
- Scope3Trace integrates PDF collection, OCR parsing, and LLM-assisted extraction.
- Achieves high accuracy in extracting Scope 1-3 totals and category-level disclosures.
- Introduces a dual-level, evidence-grounded multimodal dataset for sustainability reports.
- Addresses challenges of sparse disclosures and heterogeneous document formats.
- Enhances reliability of emissions information extraction from ESG reports.
DeepSignal Analysis
What happened
Scope3Trace is a new framework designed to extract Scope 3 GHG emissions from ESG reports. It addresses challenges such as sparse disclosures and varying document formats by using a hybrid rule-LLM approach. The framework also includes a multimodal dataset for better analysis of emissions data.
Key evidence
- Scope 3 emissions are significant as they represent the majority of corporate carbon footprints, yet their analysis is complicated by sparse disclosures and heterogeneous report formats.
- Scope3Trace employs a hybrid rule-LLM approach to enhance the reliability of emissions extraction from sustainability reports, achieving high accuracy in identifying organization-level emissions.
- The framework contributes a dual-level, evidence-grounded, multimodal dataset that includes organization-level Scope 3 disclosures extracted from various sustainability reports.
Why it matters
The ability to accurately extract and verify Scope 3 emissions data is crucial for companies aiming to reduce their carbon footprints. By improving the reliability of emissions data extraction, Scope3Trace can facilitate better corporate accountability and transparency in sustainability reporting. This is particularly important as stakeholders increasingly demand credible environmental impact assessments.

Scope 3 greenhouse gas (GHG) emissions account for the majority of corporate carbon footprints, yet remain difficult to analyze at scale due to sparse disclosures, heterogeneous report document formats, and limited evidence traceability. Existing approaches typically rely on to extract emissions information from ESG reports, but often lack explicit evidence grounding or depend on costly manual annotation and verification to ensure extraction reliability.

The study evaluates three NLP approaches—Named Entity Recognition, Keyword Extraction, and Topic Modelling—using the Their Finest Hour Online Archive to automate keyword extraction from crowdsourced WWII collections. Findings suggest that while NLP methods show promise, no single approach is sufficient, and ethical considerations in automated keyword extraction are crucial for responsible stewardship.
