premise 2.4.7

This release substantially improves carbon-dioxide-removal modelling, corrects fuel-market supplier handling, and adds several inventory and ecoinvent compatibility fixes.

Highlights

Carbon dioxide removal

  • Scale electricity and heat/fuel inputs independently using carrier-specific IAM efficiency signals, while leaving
    material inputs and biosphere flows unchanged.
  • Apply practical lower bounds to DAC energy requirements and split shared IAM production volumes between carrier-
    specific DAC routes to prevent double counting.
  • Expand CDR mappings for IMAGE, REMIND, REMIND-EU, MESSAGE, WITCH, and GCAM, including compatibility with legacy IMAGE Carbon Capture variables.
  • Add regionalized eucalyptus and poplar/willow afforestation routes for ecoinvent 3.11 and newer.
  • Add a mapped cement MEA capture-and-storage activity representing one kilogram of non-fossil CO₂ stored.
  • Harmonize wood BECCS, biomethane SMR+CCS, biomass-fermentation CCS, and cement capture inventories as host-excluding capture and storage modules.
  • Add hydrogen-heated DAC variants and improve CDR reporting, logging, classifications, and SimaPro export metadata.
  • Fix fresh imports of the coastal enhanced-weathering inventory.

Fuel markets and transformations

  • Correct cutoff fuel markets so exchanges to waste-treatment suppliers use the waste-convention sign after share normalization.
  • Exclude used-cooking-oil biodiesel with CCS from consequential diesel marginal mixes.
  • Deduplicate regionalized suppliers and consolidate duplicate technosphere exchanges in generated markets.
  • Update REMIND chemical-sector mappings to use final energy excluding non-energy use.

Inventories and ecoinvent compatibility

  • Revise the wave-energy inventory to correct machining quantities, vessel operations, component transport,
    manufacturing inputs, unsupported capital goods, and end-of-life assumptions; also fix previously unlinked exchanges.

  • Preserve activity classifications in runtime caches and restore them when loading legacy caches.

  • Make consequential blacklist replacement locations ecoinvent-version aware.

  • Add backward migration from monoethanolamine in ecoinvent 3.11 inventories to the methyldiethanolamine supplier
    available in ecoinvent 3.10.

  • Load afforestation inventories only for ecoinvent 3.11 and newer.

  • Avoid a false transport-validation failure for hydrogen transport datasets.

    Tests and documentation

    • Expand CDR and fuel-market regression coverage across IAM models, ecoinvent versions, and system models.
    • Improve LCIA regression diagnostics by reporting all divergent scores together.
    • Make the ecoinvent 3.12 superstructure test select a registered GWP method reliably.
    • Refresh affected deterministic LCIA baselines.
    • Expand the documentation for CDR transformations, carrier-specific energy scaling, fuel-market conventions, and
      updated inventories.
