Auden focuses on big scale solutions to climate change, primarily clean energy and activism. He worked previously in corporate sustainability at Rocky Mountain Institute.
Auden has been a trailer insulator, burger flipper, ambulance medic, Outward Bound instructor, high school math and English teacher, and Forest Service goose-nest island builder. He has lectured at Harvard, Yale, Google and Starbucks, and to second graders and Chilean kayakers. His writing has been published in Harvard Business Review, the L.A. Times, Scientific American, Climatic Change, Atlantic.com, Huffington Post, The Denver Post, and other media, and his work has been covered in Outside, Fast Company, Travel + Leisure and Businessweek. In 2006, Auden was named a global warming innovator by Time Magazine and in 2007 he testified to Congress on the impacts of climate change on public lands. His book Getting Green Done: Hard Truths from the Front Lines of the Sustainability Revolution was called “an antidote to greenwash” by NASA climatologist James Hansen.
Auden lives in Basalt, Colorado with his wife Ellen and their children Willa and Elias, who call him "a goofy global warming guy."
