Croke Park

Croke Park in Dublin is the largest sports stadium in Ireland and the forth largest in Europe. In 2008, the stadium began a program called Cúl Green which aims to make Croke Park — home of the Gaelic Games and host of a variety of events from concerts to soccer — the first major sports arena in the world to go carbon neutral. The program encourages fans to play their part in making the park carbon neutral by making carbon-saving pledges through their Web site.
