Environment Variables Backstage: Carmen
Feb 12, 2026
Joseph Cook, Head of R&D at the Green Software Foundation, helps build the Impact Framework. Florent Morel, former Green IT lead at Amadeus and co-creator of Carmen, now focuses on sustainable engineering. They discuss Carmen’s approach to measuring software carbon at team and component levels. Short, practical measurements, integration with observability and FinOps, and scaling standardized, transparent metrics across organizations.

Episode notes
Standardised, Re-runnable Emissions Output
- The Impact Framework (IF) separates calculation models from a standardized output format.
- That makes outputs both auditable disclosures and re-runnable proofs of calculation.
Meta-Generator For Scale
- Carmen acts as a meta-generator that creates Impact Framework manifest files for many components.
- This avoids asking hundreds of teams to implement their own measurements and ensures consistency.
Leverage Existing FinOps Data
- Combine FinOps billing reallocation with resource usage data to compute infrastructure-level emissions.
- Plug Carmen into existing FinOps processes to reuse allocation logic and avoid duplication.
