The Scope 3 Data Problem
For most companies, Scope 3 Category 4 (upstream transportation) and Category 9 (downstream transportation) represent the largest and least visible portions of their carbon footprint. Unlike Scope 1 and 2 emissions, which come from sources you own or control, Scope 3 emissions require data from dozens — sometimes hundreds — of external carriers and logistics partners.
Why Existing Tools Fall Short
Most ESG reporting tools rely on spend-based estimation models — they multiply your logistics spend by an emission factor and call it done. This approach can produce estimates that are off by 40–60% from actual emissions, which creates significant regulatory and reputational risk as reporting requirements tighten.
The Activity-Based Approach
TetriXX calculates Scope 3 emissions using activity-based methodology — actual shipment data (weight, distance, transport mode) combined with carrier-specific emission factors. The result is an emissions dataset that is accurate enough for CDP, GHG Protocol, and emerging EU CSRD reporting requirements.
