Environmental certification earned by 18 sports facilities

LAWRENCE, Kan. (AP) The Sports Turf Managers Association has recognized 18 facilities worldwide with the organization's Environmental Facility Certification. Only two of the 16 in the United States are major league venues.

The Houston Astros' Minute Maid Park, and New York Red Bulls' arena and training facility were cited. Real Madrid's practice facility and stadium in Madrid, Spain, also earned certification.

Facilities are assessed on 10 environmental criteria, including storm water management, fertilization, recycling, composting, mowing and energy conservation. To earn certification, the facilities must have at least an 80 percent score in all 10 areas. The facilities keep their certification for three years.

The Sports Turf Managers Association is comprised of approximately 2,600 people who manage sports fields worldwide.
