Nexans has been awarded the highest A rating by CDP in its 2025 Supplier Engagement Assessment (SEA), recognizing the excellence of its supplier engagement approach on climate issues and Scope 3 emissions management.
Highest score — publicly disclosed by CDP
Only companies achieving an A rating are publicly recognized by CDP, making this distinction a strong external benchmark of an industrial group’s climate maturity across its value chain.

For industrial companies, a significant portion of carbon emissions is not generated within their own operations. In manufacturing sectors, suppliers of raw materials and services can account for a substantial share of the total footprint. Taking action on Scope 3 — particularly in categories linked to the procurement of materials and services — is therefore the most important lever to align with a 1.5°C pathway, and also the most complex, as it depends on the maturity, data quality, and ambition of hundreds of partners.
The official CDP notification confirms that Nexans’ 2025 Supplier Engagement Assessment (SEA) has been rated A. This distinction confirms that its supplier engagement strategy is aligned with global best practices in Scope 3 management and the integration of climate considerations into the supply chain.
A methodology built over several years
Behind this score lies a structured approach developed and refined over the years through Nexans’ E3 model. The result is directly based on the criteria included in the CDP Climate Change questionnaire:
- Value chain mapping and identification of Scope 3 emissions
- Identification and management of supplier environmental risks
- Integration of climate requirements into supplier contracts
- Prioritization and engagement of high-impact carbon suppliers
- Year-on-year Scope 3 reporting and verification
- Climate targets linked to the supply chain.

A score, not a destination
A score is a milestone, not an endpoint. Work continues with suppliers to turn this commitment into measurable emissions reductions across the entire value chain.
This result reflects the strength of Nexans’ supplier engagement approach. More than 600 strategic suppliers are now part of this roadmap. According to CDP data, supply chain emissions are on average 26 times higher than a company’s direct operational emissions, making active supplier engagement not optional but foundational.
Nexans’ approach demonstrates how an industrial group can turn Scope 3 management into a lever for resilience and competitiveness, making environmental transparency a core criterion in supplier relationships.
