A core ontology for modeling life cycle sustainability assessment on the Semantic Web

Abstract

The use of Semantic Web and linked data increases the possibility of data accessibility, interpretability, and interoperability. It supports cross‐domain data and knowledge sharing and avoids the creation of research data silos. Widely adopted in several research domains, the use of the Semantic Web has been relatively limited with respect to sustainability assessments. A primary barrier is that the framework of the principles and technologies required to link and query data from the Semantic Web is often beyond the scope of industrial ecologists. Linking of a dataset to Semantic Web requires the development of a semantically linked core ontology in addition to the use of existing ontologies. Ontologies provide logical meaning to the data and the possibility to develop machine‐readable data format. To enable and support the uptake of semantic ontologies, we present a core ontology developed specifically to capture the data relevant for life cycle sustainability assessment. We further demonstrate the utility of the ontology by using it to integrate data relevant to sustainability assessments, such as EXIOBASE and the Yale Stocks and Flow Database to the Semantic Web. These datasets can be accessed by the machine‐readable endpoint using SPARQL, a semantic query language. The present work provides the foundation necessary to enhance the use of Semantic Web with respect to sustainability assessments. Finally, we provide our perspective on the challenges toward the adoption of Semantic Web technologies and technical solutions that can address these challenges.

Data implementation matters: Effect of software choice and LCI database evolution on a comparative LCA study of permanent magnets

“…Some other initiatives worth mentioning are BONSAI and ODYM because these address the possibility of harmonizing and sharing data that comes from different contexts and from the use of different tools such as LCA, material flow analysis, and environmental input output (Ghose et al, 2022; Ghose et al., 2019; Hansen et al., 2020; Pauliuk & Heeren, 2020).…”

Life cycle inventory analysis modelling in LCSA: from basic aspects to advanced techniques

“…There are also other techniques to consider for LCSA, for example big data and cyber-physical system (Riedelsheimer et al, 2021). Finally, to facilitate all these techniques, it is advised to have a core ontology for LCSA modelling (Ghose et al, 2022). Some examples are:…”

Time To Move From Accounting to Decision Support? Considerations for Improved Emission Disclosure Before the CSRD

“…However, in practice a prerequisite and barrier is data foundation. cLCA data is growing, but as carbon footprints are becoming an increasingly marketable parameter, there is need for an ontology with transparency and provenance which enables preservation of both decision support ability and proprietary information [44,45] such that suppliers can showcase their market-aligned characteristics. Rearranging the existing structures to enable this will only become more difficult the more entrenched aLCA becomes, unless there is greater adoption of systems thinking.…”
