More about him

Reiner is a chemical scientist by education with a focus on environmental chemistry. To create a better world to live in was always his goal and so it is not a surprise that Sustainability, and all it’s related subjects, became his career foundation. Having lived for 12 years within the supply chain in Asia and confronted with different cultures, in direct contact with suppliers and workers, he gained extensive experience in creating impact by doing things differently, successfully embedding practices that benefit the business by integrating sustainability.

Reiner has worked for almost 18 years in this space, having set up the compliance and sustainability department in the international sporting goods company PUMA. As Global Director for Sustainability and Compliance, Reiner was responsible for 23 global experts within the field of sustainability. He has a proven record of delivering sustainability programs and strategies, from externally-driven compliance to the integration of sustainability at the beginning of major business decisions/actions with a clear focus of sustainability’s value added to core business. The world’s first Environmental Profit & Loss account, the PUMA E P&L, was developed in his department and under his leadership. Reiner chaired the Sustainability Committee of the European Sporting Goods Association (FESI) based in Brussels.

Reiner is an “ad personam” member of the steering committee “Science Platform Sustainability 2030 – UN-SDGs 2030” established in Germany, which operates as an independent organization and where he actively contributes to developing actionable solutions for transformation processes to create a more sustainable society. The platform is receiving cross-ministerial support throughout its development and operation and is under the supervision of the office of the Federal Chancellery in Germany.

He supported the establishment of the Sustainable Textile School in September 2017 and he is still engaged with its ongoing development.

Michael Braungart

Michael Braungart

Prof. Dr. Michael Braungart, founder of the EPEA C2C institute in Hamburg/Germany, is a chemist and widely known for his work with the Cradle to Cradle design concept, which he developed together with the American architect William McDonough. Cradle to Cradle® offers companies the opportunity to present their products as no longer just for sale, but as available for use. After the use of the product, the materials are taken back as part of a reprocessing system and therefore remain in circulation. Companies may become less dependent on price fluctuations in raw materials markets. The economy of the whole value creation cycle is improved: the value chain is viewed from raw materials to the remanufacture of the product.
