Sustainability Rating (S-Rating)

The Sustainability Rating (S-Rating) assesses our suppliers’ sustainability performances. The tools used for rating our suppliers are the Sustainability Self-Assessment Questionnaire (SAQ) as well as an on-site check in case a higher sustainability risk is identified. The rating is determined location-based.

In addition, selected suppliers are required to go through an in-depth anti-corruption assessment (BPDD).

The Self-Assessment Questionnaire (SAQ)

Suppliers are required to complete a Self-Assessment Questionnaire (SAQ) on Sustainability, which covers the areas of human rights and working conditions, environment, business ethics, supplier management as well as the responsible sourcing of raw materials. The joint SAQ was developed by the members of the industry initiative Drive Sustainability , facilitated by CSR Europe. The SAQ is provided on the external platform by the service provider NQC Ltd. Due to the standardized questionnaire used by several OEMs, suppliers can complete the SAQ once and voluntarily share their responses with different buyers. By this, we aim to reduce the workload for suppliers who do not need to complete several different sustainability questionnaires from different buyers.

Please find the SAQ as a pdf in several languages here:

Furthermore, you can find frequently asked questions (FAQ) on the SAQ below. Pleas note that the SAQ cannot be completed by filling out the pdf document. In order to complete the SAQ, a registration at is necessary.

In addition, the following document shows some focus areas of the SAQ and can support when creating a code of conduct or management systems:

The On-Site Check (OSC)

If the above mentioned minimum requirements are not met and/or the responses in the SAQ point to an increased sustainability risk, an On-Site Check (OSC) is conducted at the supplier’s site. This check aims at evaluating our suppliers’ sustainability performance and at helping to improve it if gaps and nonconformities are identified. The OSC is conducted by an independent external partner, which is an internationally experienced audit company. After an On-Site Check, our suppliers are informed about the result and a corrective action plan is developed if necessary.

Please note that the SAQ result is still relevant in the assessment of suppliers’ sustainability performances, even if an OSC is conducted.
