Enabling Corporate Sustainability Through Emissions-Related Supplier Evaluation

  • In light of increasing regulatory requirements and international climate ambitions, the decarbonization of global supply chains is gaining strategic importance. The manufacturing sector is central to this transformation, given its substantial contribution to global greenhouse gas emissions. This study aims to develop a practical model for evaluating suppliers according to their emissions performance. A structured set of evaluation criteria was derived from a systematic literature review, analysis of established sustainability standards, and five expert interviews. These criteria were consolidated into a structured model capturing key indicators of a company’s decarbonization efforts and subsequently translated into a supplier evaluation tool. By enabling a more transparent assessment of supplier decarbonization efforts, the model supports informed decision-making and facilitates the integration of decarbonization objectives into procurement practice. The tool enables companies to systematically collect relevant information, enhances transparency and comparability along the supply chain, and supports the integration of emissions-related criteria into procurement strategies. Validation through practitioner interviews confirmed the model’s practical applicability while also highlighting key challenges, such as inconsistent PCF data and limited data availability. Overall, this work contributes to the operationalization of corporate decarbonization strategies in industrial procurement and addresses a gap between theoretical frameworks and their implementation in emissions-related supplier evaluation.

TuWAs: Transformation hub for metal forming value chains in the powertrain

The aim of the research project 'TuWAs' is to establish a transformation hub that enables companies in the massive forming sector to meet the challenges of disruptive megatrends.

Duration: 01.11.2022 – 31.12.2026
Funding no.: 16THB0007D
Project homepage: tuwas-hub.de
Funding: Federal Ministry for Economic Affairs and Energy (BMWE)
Promoters: VDI/VDE Innovation + Technik GmbH

Acknowledgments: 
The project is funded by the Federal Ministry for Economic Affairs and Climate Action (BMWK) on the basis of a resolution of the German Bundestag. Project sponsorship is provided by VDI/VDE Innovation + Technik GmbH within the framework of the Innovation Promotion Program.

Benefits for the target group:
The largely medium-sized companies in the massive forming sector often lack the capacities and expertise necessary for transformation. The transformation hub 'TuWAs' aims to enable these companies to transform themselves with individual support services in order to prosper in a sustainable and digital future with changed mobility, working and living environments. Participation in the project or the utilisation of TuWAs' range of services does not involve any financial outlay for interested companies.
