New York Mayor Michael Bloomberg — with the help of green friends like “Wicked” witch Elphaba — launched the “Broadway Goes Green” initiative Tuesday that includes plans to use energy-saving bulbs and recycle stage sets. The aim of the campaign is to reduce Broadway’s carbon footprint, a measure of greenhouse gases produced by human activity. Ten theaters already have replaced some 10,000 bulbs with more energy-efficient ones. And within the next 12 months, all of Broadway’s theaters will have made the switch.
