To date, only a limited number of data sources for the sustainability assessment of a diverse range of chemicals exists, including public databases such as the ecoinvent or IDEA databases, datasets from industry associations such as PlasticsEurope , or commercial databases such as the GaBi or cm.chemicals databases. These form the data basis for assessing the sustainability of chemicals by scientists, regulators and the industry. Noticeably, most data is provided in an aggregated form without detailed process-specific documentation. Consequently, the assumptions and calculations behind these datasets cannot be evaluated or reproduced by users. In contrast, the ecoinvent database provides detailed documentation per disaggregated gate-to-gate dataset and thus allows for a systematic analysis of the quality of datasets in the chemicals sector.
