sci.Scope-1-2-3-GHG-emissions Calculator
Calculates Scope 1 (direct), Scope 2 (purchased energy), and Scope 3 (value chain) greenhouse gas emissions in tonnes CO₂-equivalent using IPCC emission factors. Scope 3 typically represents 70–90% of corporate total GHG footprint — mandatory reporting under CSRD and SEC climate disclosure rules includes all three scopes.
