Documented references, explicit limits
These collections combine provider disclosures, lifecycle studies and public data. The generator transforms some sources into derived factors. A daily rebuild does not mean all sources were refreshed.
Missing values appear as a dash and are never converted to zero. Zeros already in files are preserved; some collections use zero as a convention. Filled and carried-forward values are not individually flagged in the current series.

Electricity impact factors
Factors modeled from electricity mixes and lifecycle references. Available periods may include carried-forward or estimated values.
The ‘Renewables only’ variant (‘-green’ files) keeps bioenergy, hydro, solar and wind, then recalculates their shares to total 100%. Impact factors are calculated from this hypothetical mix. This scenario describes neither the territory’s actual mix nor a green electricity offer, and its impacts are not zero.
Sources and limitations
Electricity mix
The mix combines generation and imports using the generator methodology. “Green” selects Bioenergy, Hydro, Solar and Wind and renormalizes their shares; it is not a contractual renewable-electricity measurement.
Sources and limitations
Cloud infrastructure
Provider disclosures differ in boundary and reporting year. Zero may represent a dataset convention rather than no impact. REF and CFE are not interchangeable metrics.
Sources and limitations
AI models
The catalog may include legacy models. The open field is not a license. estimated flags estimated fields; no per-model environmental footprint is provided.
Sources and limitations
Digital equipment
Modeling references, not measurements of individual devices. Do not interpret a /s factor as the total embodied impact of a device.
Sources and limitations
Energy technologies
Lifecycle factors from literature references. They do not describe instantaneous power-plant emissions.
