Record & Auto-Calculate
All 3 Scopes and 7 greenhouse gases per TGO / IPCC / GHG Protocol — every input channel shares one calculation logic, so figures never drift
26 activity types + special modules (septic tanks / N-P-K fertiliser / refrigerants / trees)
Calculation preview before saving, with an automatic audit trail
Duplicate-entry protection + evidence attachment right on the entry form
Recording and calculation is the heart of GCarbon — a Scope 1/2/3 engine of 97+ features, with specialist modules most platforms lack.
26 activity types covered
From stationary/mobile fuel, electricity and steam to purpose-built modules: septic tanks and wastewater (methane), N-P-K nitrogen fertiliser (N₂O), refrigerant leakage (HFCs), employee commuting by travel mode, per-capita paper, and tree sequestration.
Scientifically correct by construction
Every entry computes all 7 gases × IPCC AR5 GWP into kg CO₂e, splits biogenic CO₂ per ISO 14064-1, and converts units dimension-aware — litres, kilograms, kWh, kilometres are handled for you.
Preview before save, trace forever
Forms show a live calculation preview before saving, duplicates are blocked automatically, evidence attaches right on the form, and every change lands in an immutable audit trail.
