🌫️ GHG Calculator — Scope 1 & 2 (+ key Scope 3)

Build a defensible greenhouse-gas inventory: enter activity data, the tool applies sourced emission factors (ADEME Base Empreinte orders of magnitude, IEA grid factors) and produces totals by scope, a Pareto of posts and a BEGES-style report.

Default factors are public orders of magnitude (ADEME Base Empreinte, IEA 2023 grid intensities: Morocco ≈ 0.61 kgCO₂e/kWh, France ≈ 0.052). Override any factor with your supplier/ADEME value and cite it. For regulatory BEGES (France, 500+ employees) or CSRD reporting, have the inventory reviewed by a specialist.
