Six clubs from the Bundesliga and the second division (VfL Wolfsburg, Werder Bremen, VfB Stuttgart, FC St. Pauli, SC Paderborn 07 and Bayer 04 Leverkusen) took part in the 'sustain Club' sustainability certification and as part of that process Bayer 04 were awarded the 'sustain Club silver’ certification.
With the achievement of this certification, the sextet of clubs assumed a pioneering role in professional sport. In cooperation with the Swiss organisation 'sustainable///sports', a pilot phase was held to develop the 'sustainedClub' standard, which was certified by the independent expert organisation DEKRA. It was the first recognised sustainability standard and orientation point in professional football.
"As a club, we are very happy about achieving silver status. I'd like to thank everybody who made a contribution to that," said Fernando Carro, chairman of the board at Bayer 04. "In this assessment by the experts, we not only recognise an award but we also value it as an additional incentive to continue to develop in the area of sustainability."
The six participating clubs have accepted the challenges relating to sustainability in professional football and are committed to a better future in the three areas of sustainability (economy, ecology and community). The standard involves the establishment of a CSR and sustainability management system, sustainability analysis and the identification of concrete improvement opportunities.

The Werkself conceded a goal at home for the first time since the beginning of January 67 minutes into the game against FSV Mainz 05 on Saturday. Jarell Quansah levelled late on for the final score of 1-1 to secure a point and avoid a first home defeat in six games. Bayer 04 were very critical of their performance after the game.
