Overview

A Professional Services Firm Ready to Ditch the Survey

Grant Thornton, a global leader in professional services and consulting, needed a smarter way to handle Scope 3 reporting. With a complex supplier network, the firm was under pressure to deliver accurate disclosures quickly and efficiently — while reducing reliance on manual questionnaires and outdated data-gathering methods. DitchCarbon became that partner — replacing surveys with automated data collection and helping Grant Thornton accelerate their sustainability reporting with confidence.

The Challenge

Slow, Costly, and Still Getting It Wrong

Grant Thornton's procurement and sustainability teams faced recurring obstacles:

• Emissions data collection was dependent on manual questionnaires through platforms like EcoVadis and CDP.
• Processes were slow, resource-heavy, and costly, with little year-over-year improvement.
• Accuracy was inconsistent, leaving reports vulnerable to gaps and errors.

"Many firms are moving away from platforms like EcoVadis. Sending questionnaires seems nonsensical when the reality is that all necessary emissions data is already publicly available."

The Solution

Automated Data From Audited Public Disclosures

Grant Thornton turned to DitchCarbon to eliminate survey fatigue and automate data sourcing. Instead of relying on supplier responses, DitchCarbon applied its technology to extract and normalize emissions directly from audited, publicly available disclosures. Key capabilities included:

• Automated data extraction from supplier reports and filings.
• Normalization and validation aligned with GHG Protocol standards.
• System-ready outputs for ESG and procurement platforms.

"Questionnaire-based platforms create more problems than they solve — cost, complexity, and limited accuracy. DitchCarbon gives us exactly what we need, quickly."
