As part of our commitment to social and environmental excellence, we reinforced our responsible procurement approach by partnering with Achilles in November 2023. This leading sustainable sourcing platform enables us to assess and support our suppliers against rigorous ESG criteria, aligned with ISO 14064 and SBTi standards.
In 2024, we continue this initiative by integrating the Achilles score as a key selection criterion while setting evolving requirements for our partners. Operating across 17 countries, Achilles provides independent supplier audits, enhancing transparency and compliance while addressing the Principal Adverse Impacts (PAIs) under the EU Taxonomy.
Thomas Roth, Head of Procurement & Supply Chain
“In the highly competitive solar energy sector, balancing responsible sourcing with competitiveness is critical , both for our ESG strategy and to meet shareholder expectations. We established a strict Supplier Code of Conduct but wanted to go further by selecting Achilles. Their platform ensures an independent ESG qualification process, delivering a robust and transparent assessment of supplier practices.”
This initiative continues to reinforce our commitment to a sustainable supply chain, in line with our CSR objectives.
The ACHILLES platform is used to perform ESG assessments for all suppliers and contractors, providing a ranking from A to E. At the qualification stage, a minimum ranking of “C” is required to validate ESG criteria. For key suppliers and EPC contractors not registered on ACHILLES, a specific ESG evaluation questionnaire is applied requiring a minimum score of 12 points to validate ESG criteria at the qualification stage.

Achilles uses a letter-rating system (A, B, C, D) within their overall scorecard to signal a supplier’s performance relative to benchmarks:
A – Excellent: Suppliers scoring 81+ are in the top 15% of Achilles’ network—demonstrating outstanding performance.
B – Good: Scores between 61–80 are above average and indicate generally strong performance with room for refinement.
C – Requires Improvement: Scores from 46–60 suggest noticeable gaps; buyers are encouraged to seek further evidence or engage the supplier proactively.
D – Poor/High Risk: Scores ≤ 45 are considered low-performing and high-risk, prompting heightened due diligence or intervention.
