Worldchanging was a nonprofit online publisher that operated from 2003 to 2010. Its strapline was A bright green future. It published newsletters and books about sustainability, bright green environmentalism, futurism and social innovation. History Worldchanging was launched in October 2003 in San Francisco by Alex Steffen, Jamais Cascio, and a core of initial contributors. In 2005, Worldchanging moved its offices to Seattle, Washington. In early 2006, Cascio left to form the website Open the Future. From 2005–2010, Worldchanging was headquartered in Seattle with Alex Steffen as executive editor and editorial lead, Julia Levitt and Amanda Reed as managing editors, and several contributing editors including Jeremy Faludi and Sarah Rich. It relied extensively on an international network of writers and correspondents. Worldchanging was overseen by a board of directors, led by Worldchanging's chairman, the environmental photographer Edward Burtynsky until May 2010. Worldchanging was supported by grants, book sales, speaker fees and reader donations. On November 29, 2010, Worldchanging announced that due to fundraising difficulties it would shut down. It was acquired by Architecture for Humanity in September, 2011. That organization subsequently filed for bankruptcy in January 2015, and the Worldchanging website became unavailable around March 2016.

In the opening paragraph of its manifesto, Worldchanging declared: Impact This pithy remark is an indication of the impact Worldchanging had in the first decade of the twenty-first century. Much environmental reporting of the time was preoccupied with predictions of social and ecological collapse unless there was a wholescale retreat from industrial modernism. Worldchanging provided a welcome breath of optimism. It demonstrated that, not only were there solutions to even the most pressing problems, they were available now. This school of thought has come to be known as bright green environmentalism. Reflecting on the closure of Worldchanging in 2010, Andrew Revkin contrasted its work with The World Without Us, which examined how quickly nature would erase the works of civilisation were humans to suddenly disappear. He summarised Worldchanging's work as taking on "the tougher challenge of charting life on the World *with* us". Critical reception Wired columnist Bruce Sterling called Worldchanging "The best collaborative weblog in the whole wide world". Journalist and author Bill McKibben considered it "one of the most professional and interesting Web sites that you
