Audit embodied carbon on every BOM. Keep the human in the loop.
Construction is 37% of global energy-related CO₂ — most of it decided at the Bill-of-Materials stage. GreenGate's agent audits each BOM against the ICE Database and proposes lower-carbon substitutions. The responsible engineer approves each swap with a single push on their phone — cryptographically bound to the decision via Auth0 CIBA.

− 0 kg CO₂e
Auditable by construction
Every suggestion is pinned to an ICE Database factor and a materialized kg CO₂e delta. No hallucinated numbers.
Signed by the human
Substitutions require a CIBA-bound approval from the responsible engineer. Audit trail (auth_req_id, timestamp, user) persisted for CSRD / SB 253.
Built on real BOMs
Works on line-item BOMs from architect specs, not on whole-building estimators.
How it works
Agent runs the audit
GreenGate parses the BOM, matches each line to an ICE Database emission factor, and ranks hotspots by kg CO₂e.
Substitutions get proposed
Gemini proposes lower-carbon alternatives with a technical rationale and a risk flag. Every proposal carries a signed delta.
A human signs off
The responsible engineer receives a CIBA push on their phone with the exact substitution description. One approval binds the decision cryptographically.
