Coverage and modelling detail

Explore geographic coverage, dataset reference periods, industry-process detail, material specifications and LCIA methods to assess their fit for your LCA model.

Geographical coverage: 399 geographies across China, including 353 city-level and local, 32 provincial-level, 7 regions, 6 power grids and 1 national.
Temporal coverage: 97.3% of the 136,474 HiQLCD 1.5.0 internal records have reference periods ending in 2024–2026, as of October 14, 2026. Top three time periods by record share, grouped by start and end year: 2022–2024 (28.8%), 2021–2024 (14.5%), and 2023–2025 (10.1%). Reference periods are not annual observations or update dates.
Technological detail: 2,311 aluminium datasets in the cut-off model, covering value-chain stages, processing, alloy grades and feedstock.
LCIA method coverage: 42 method configurations, including versions and variants, in the October 30, 2026 sample snapshots. Selected examples include IPCC 2021, EF v3.1, CML v4.8 2016 and ReCiPe 2016 v1.03.
