The Problem

Carbon reporting is
still stuck in spreadsheets

The construction industry causes 39% of global CO₂. Yet most firms track embodied carbon manually — slowly, inconsistently, and too late.

❌ Without CPER
⏱ 2–5 days per project, manual EPD lookup
📄 Spreadsheets full of errors and guesswork
🔍 Carbon discovered after goods are on site
📋 BREEAM report takes a week to compile
⚠️ CSRD deadline approaching, no system in place
