With Pittsburgh as host of last year's World Environment Day, groups all over the region organized outstanding events around environmental issues, putting us in the spotlight once again. Our city has long been a leader in sustainability, from green buildings to green parks and green spaces--and soon we might have the greenest building on the planet with the planned PNC Tower. The region's turnaround from an industrial town to a green city has caught the attention of national media and continues to be a driving force in our revitalization.
