Enables more accurate baseline comparisons and clearer result interpretation
Supports filtering and segmentation in analytics dashboards and reporting tools
Ensures compliance with location-based frameworks such as EU Level(s) and national LCA standards
By capturing location data upfront, this change enhances model fidelity and aligns your workflows with the direction of LCA regulation — where regional specificity is rapidly becoming mandatory.
Projects can now be marked classified, hiding their names from shared analytics, dashboards, and usage summaries. This helps protect NDA-bound, competitive, or internal R&D work while still allowing participation in aggregated platform insights.
Projects can also be marked as classified, which hides project names from shared usage insights, dashboards, and organizational summaries. This is essential for NDA-bound projects, confidential R&D, or competitive tenders. Existing projects are treated as classified by default.
Product LCA & EPD updates
A new benchmarking feature flags EPD results that fall outside typical performance ranges using reference data from the One Click LCA database. This helps catch input or modeling errors earlier, improving quality and reducing verification back-and-forth.
The plausibility checker will be made available during July.
Expanded regional datasets improve regulatory alignment and modeling accuracy
