Identify the Emission Hotspots Worth Sharpening.
See emission intensity hotspots – by category, supplier, region, and product. Decide where collecting supplier primary data is worth the effort, and where modeled data is good enough. A directional baseline turns into a clear picture of reality.
Supplier-Specific Data, Matched to Where It Counts.
Primary data only lifts your inventory if it's both deliverable for the supplier and decision-relevant for the number. ctrl+s matches granularity to value: supplier-level inputs where that's the right level, streamlined PCF where it changes the number, full PCFs where suppliers already maintain them. Implausible inputs are flagged automatically. The result: primary data that actually improves the inventory – without forcing every supplier into a one-size-fits-all template.
Compounding Quality, One Baseline.
Each round of supplier inputs feeds back into the same baseline, under the same methodology. Supplier-provided share grows cycle by cycle; modeled data holds the rest. The 2025 inventory becomes the 2026 inventory – sharper every reporting year, not a project to redo.
