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.

🧮

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

01

Agent runs the audit

GreenGate parses the BOM, matches each line to an ICE Database emission factor, and ranks hotspots by kg CO₂e.

02

Substitutions get proposed

Gemini proposes lower-carbon alternatives with a technical rationale and a risk flag. Every proposal carries a signed delta.

03

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.
