What's new

HiQLCD 1.4.1 revises the LCIA results of 1.4.0 and retains 31,744 datasets (CUT_OFF). LCI values are bit-for-bit identical across all three system models. The LCIA result catalog is revised to 770 category indicators; GWP100 results under IPCC 2021 and EF v3.1 EN15804 remain consistent. Models using only GWP100 can continue using 1.4.0 results; use 1.4.1 for other impact categories.

Data team statement

Translated from the Chinese statement provided by the HiQLCD data team.

  • Datasets and inventories are the same as in 1.4.0.
  • Corrects calculation result issues in 1.4.0 by recalculating LCI/LCIA results.

Changes

The comparison covers 1.4.0 to 1.4.1, checking CUT_OFF, CONSEQUENTIAL and EN_15804 separately. All three models retain their dataset sets.

Impact assessment

The LCIA result catalog changes from 1,942 rows to 770 category indicators, retaining all 770 indicator identifiers shared by both versions. The method catalog lists 44 impact assessment methods. Clients link results by complete indicator identifier during migration and record the source version as 1.4.1.

Result changes

Across all three system models from 1.4.0 to 1.4.1, all 477,680,520 LCI values are bit-for-bit identical. The climate change / GWP100 results under IPCC 2021 and EF v3.1 EN15804 remain consistent, with differences within floating-point rounding. Models using only GWP100 can continue using 1.4.0 results; use 1.4.1 for other impact categories.

The following compares the 770 category indicators shared by both versions. Relative difference is abs(new−old) / max(abs(new), abs(old)). Selection thresholds use each indicator’s maximum absolute value across both versions and all datasets; selected result cells and dataset counts are reported separately for each threshold.

Known issues and limitations

Sector tags overlap. Inventory revisions are counted by changes in core inventory fields; metadata revisions are counted separately.

Confirmed issues

No formal issue register has been obtained.

Documentation completeness (r1 field coverage)

Descriptive documentation is inherited from 1.4.0; score coverage counts populated fields. Pending documentation: formal release date, formal revision notes, and itemized notes for the 1,172 rows removed from the result catalog. Result-change statistics use two numerical thresholds, with the selected scope reported separately.
