For the eighth consecutive year, "Green Is Universal" — NBCUniversal’s sustainability initiative in partnership with the Arbor Day Foundation — will kick off its annual tree-planting campaign during the "Christmas in Rockefeller Center" broadcast. This year viewers can "Share a Tree" to a national forest, by using #ShareATree or visiting GreenIsUniversal.com to create and share an animated holiday story. Each action will contribute to the Arbor Day Foundation’s tree-planting efforts, funded by a $25,000 donation from NBCUniversal.
