Inventory & impacts

Inspect every exchange and its contribution to the selected EF v3.1 indicator.

Precalculated screening profile

Environmental impacts

Results per kilogram, using UVEK 2025 and the ecoinvent 3.10 biosphere. Exchange rows are shaded from green to red by relative contribution to the selected indicator.

Climate change 280.829 kg CO2-Eq / kilogram
Screening result

This screening result uses Brightpath mappings from the source background to UVEK 2025; mapped suppliers are not claims of scientific equivalence.

Quality and maturity details Expand Collapse

Quality and maturity

TRL scale Higher is more mature. 9: routine commercial deployment 8: commercial, but still niche or scaling 7: first-commercial or advanced demonstration 6: engineering-scale demonstration 5: pilot or large prototype 4: bench or lab validated 3: research-stage concept Technology readiness level
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: Requested

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