Life cycle assessment (LCA) manifests in two parallel streams in industries; Design focused Environmental Product Declarations (EPDs) and procurement driven Product Carbon Footprints (PCFs), each with different objectives, data and verification methods. This paper investigates how to align and integrate supplier specific PCFs into EPDs efficiently, aiming to reduce redundancy, improve data quality and enhance reporting clarity. A structured analysis is conducted in this paper investigating three integration scenarios, namely: Hybrid, scaling, and separate approach. A case study on electrical switchgear components showcased that the hybrid approach yielded a 7.5% reduction in GWP with higher supplier data utilization. Hybrid integration offers a viable pragmatic path forward balancing accuracy and simplicity. Broader adoption will require standardization of data formats and verifier acceptance.

摘要

Life cycle assessment (LCA) manifests in two parallel streams in industries; Design focused Environmental Product Declarations (EPDs) and procurement driven Product Carbon Footprints (PCFs), each with different objectives, data and verification methods. This paper investigates how to align and integrate supplier specific PCFs into EPDs efficiently, aiming to reduce redundancy, improve data quality and enhance reporting clarity. A structured analysis is conducted in this paper investigating three integration scenarios, namely: Hybrid, scaling, and separate approach. A case study on electrical switchgear components showcased that the hybrid approach yielded a 7.5% reduction in GWP with higher supplier data utilization. Hybrid integration offers a viable pragmatic path forward balancing accuracy and simplicity. Broader adoption will require standardization of data formats and verifier acceptance.
