Castellan Professional Group

Deadline Pressure

Castellan Professional Group needed a faster way to compile emissions data ahead of annual disclosure deadlines. Analysts were pulling figures from a dozen sources — utility portals, travel management systems, and vendor spreadsheets — with no reliable way to verify completeness until the final week.

Streamlining the Compile

Ordinant Carbon Solutions gave Castellan a structured intake and review process:

• Office administrators upload utility and facilities data on a fixed schedule
• The sustainability team reviews submissions against a pre-disclosure checklist
• Leadership sees real-time completion rates across all locations

1. Map data sources and assign location-level owners
2. Configure quarterly submission windows with automated reminders
3. Run the first annual disclosure entirely within the platform

“We used to spend the last ten days before disclosure just assembling files. That time is gone.” — Ines Barbero

Impact

Castellan’s sustainability analysts now focus on analysis rather than assembly, entering disclosure season with confidence that underlying evidence is complete and reviewable.
