Persistent data gaps limit the quality of life cycle assessments (LCAs), which frequently rely on incomplete, outdated, or non-comparable process data. Digital product passports (DPPs), initially developed for supply chain traceability, regulatory compliance, and circular economy objectives, also hold potential to address long-standing data challenges in LCA. Based on 20 selected, publicly documented DPP initiatives assessed a...

At the same time, kelp conservation and restoration efforts are expanding rapidly across regions, but measures of success and syntheses tend to primarily focus on eco...
