Description

This dataset represents the gearbox, for lorry used in the scalable, component-based heavy-duty vehicle inventory of Wolff et al. (2020). That study combines primary and secondary data to compare life-cycle impacts of internal-combustion, hybrid, battery-electric, and fuel-cell trucks. This activity should therefore be interpreted as a foreground vehicle-production subassembly within truck manufacture rather than as a generic standalone market dataset.

Source review: Wolff2020 supplies scalable European heavy-duty tractor component-production inventories from material manufacture through final assembly; vehicle use, fuel supply and end-of-life are excluded. Source software/background are GaBi with ecoinvent3.3/thinkstep6.115(2017), not a replacement for CLIC's profiles. Secondary data, mass models and expert interviews are used;2020 publication does not date every input. This node has reference1kilogram of gearbox, for lorry; retain source component normalization, CLIC supplier/process proxies and later corrections separately.

Methodology notes
Wolff2020 supplies scalable European heavy-duty tractor component-production inventories from material manufacture through final assembly; vehicle use, fuel supply and end-of-life are excluded. Source software/background are GaBi with ecoinvent3.3/thinkstep6.115(2017), not a replacement for CLIC's profiles. Secondary data, mass models and expert interviews are used;2020 publication does not date every input. This node has reference1kilogram of gearbox, for lorry; retain source component normalization, CLIC supplier/process proxies and later corrections separately.
System boundary
Component-production reference, derived from the truck study's cradle-to-gate inventory. Linked supplier manufacturing, direct emissions and disposal/replacement overlap require separate reconciliation.

Use limitations
Partial source comparison. Dry engine SI mass1140kg differs from printed Table4 total1206kg; native/paper definitions are retained, not blindly renormalized. Cab heat total labelledkWh adds MJ subtotals and printed TableA2 saysMJ; other heatkWh/MJ labels require ancestor verification before any3.6rescaling. Tyre acetylene differs by10between SI and printed table. Natural-gas mass/volume conversion requires reference conditions. Source power-electronics sheet has detailed materials/processing but no declared total normalization; do not sum process solvents into a finished-device mass without justification. No formal Wolff erratum found in scoped checks. Publisher HTML/PDF update dates alone do not establish inventory corrections. Hawkins2013 corrigendum changes EV motor/inverter/charger and additional battery packaging; applicability must be traced to each reused component, not applied across every glider or rail process.

1 to 5 scale Lower is better. 1: strong market- or operating-data basis 2: commercially plausible, but still somewhat specific 3: partly representative, with modelling or adaptation bias 4: pilot, proxy-based, scaled-up, or prospective 5: weak representation of the real technology state Technological representativeness
1 to 5 scale Lower is better. 1: geography matches the claimed scope well 2: regionally credible, but broader or less exact 3: generic regional or global proxy 4: weak proxy or clear geographic mismatch 5: geography is effectively unsupported Geographical representativeness
1 to 5 scale Lower is better. 1: current for that technology class 2: slightly dated, but still good 3: dated enough to need caution 4: stale, pilot-era, or prospective relative to current practice 5: clearly not representative of the current state Temporal representativeness

Missing exchange uncertainty generation: Not requested

Representativeness scores use a 1–5 scale when provided. Lower scores indicate a closer fit to the modeled technology, geography, or time period.
