Wintershall Dea is committed to trusted relationships with its suppliers.

Wintershall Dea Procurement
Wintershall Dea

As global Procurement with a local presence in our business units, Wintershall Dea procures products and services worth more than a billion euros annually. The company works with our suppliers and contractual partners in a trusting, personal manner while observing the highest standards. We qualify our suppliers taking account of the following aspects: sustainability, respecting human rights, quality, compliance with high technical and HSE standards. Wintershall Dea therefore makes its procurement decisions taking these aspects into account. The company is interested in fair and long-term supplier relationships.

Sustainability in the supply chain – our expectations

For Wintershall Dea, sustainability-oriented management of the supply chain means raising the awareness of our expectations and standards among our suppliers.

The company expects all suppliers to comply with applicable laws and internationally recognized environmental, social and corporate governance (ESG) standards. And that our suppliers do all they can to ensure that their suppliers and subcontractors also implement these standards.

In selecting suppliers and assessing new and existing supplier relationships, protection of the environment, respecting human rights, compliance with labour and social standards, and anti-discrimination and anti-corruption guidelines are also relevant for Wintershall Dea alongside economic criteria.

Our understanding of these ESG standards is reflected in the Code of Conduct, which can be found in the download centre.

If you have any concerns about unlawful conduct or misconduct, please contact the responsible BASF Compliance Hotline.

We accept our responsibility for protecting the environment and the climate and shape our processes in such a way that the environment impact and energy and resource consumption are minimised. As part of the sustainability strategy the company has implemented the DIN EN ISO 50001 Energy Management System at relevant locations.

Against this background, Wintershall Dea has a strong interest in improved energy efficiency for the machines, systems, products, services or facilities we use. Procurement decisions are therefore made taking these aspects into account.
