In the new season, the Bundesliga soccer league is somewhat less green, following the relegation of Werder Bremen's Green-Whites. But there is still VfL Wolfsburg, which is playing right at the top - both in terms of sport and environmental protection. Another newcomer is Greuther Fürth, the "Kleeblättler" from Franconia. In the meantime, however, all clubs are making an effort when it comes to environmental performance. ISPO.com does the soccer sustainability check.
