What we measure, and what we don't
- Included: ad delivery (impression-side), measurement, creative serving, and the share of platform infrastructure attributable to delivered impressions.
- Included: ADmetric AI compute and storage, allocated by customer share of usage.
- Excluded: production of creative assets, end-user device energy, and outcomes attribution.
- We never net offsets against gross emissions. Reductions come from channel mix and inventory choices, not certificates.
- Numbers are recomputed monthly from primary data; methodology version pinned on every report.
