From 2005 - 2010, Worldchanging was headquartered in Seattle and led editorially by Alex Steffen, the executive editor, with managing editor Amanda Reed, contributing editors include Jeremy Faludi and Sarah Rich, among others. It relied extensively on an international network of writers and correspondents, see list below. Worldchanging was overseen by a board of directors, lead by Worldchanging's chairman, the environmental photographer Edward Burtynsky. 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 has since merged with Architecture for Humanity, though detailed plans for the site's future have not been released.
Worldchanging practiced "solutions-based journalism,"  that is, the explicit goal of its work is to highlight possible solutions to what the editorial team sees as the planet's most pressing problems, rather than to spread news of those problems or critiques of their causes. Executive editor Alex Steffen was quoted in the Guardian  explaining the value of this approach by saying "Cynicism is often seen as a rebellious attitude in western popular culture, but in reality, our cynicism advances the desires of the powerful: cynicism is obedience."
In its manifesto, Worldchanging declared:
"Worldchanging is a solutions-based online magazine that works from a simple premise: that the tools, models and ideas for building a better future lie all around us. That plenty of people are working on tools for change, but the fields in which they work remain unconnected. That the motive, means and opportunity for profound positive change are already present. That another world is not just possible, it's here. We only need to put the pieces together. Informed by that premise, we do our best to bring you the most important and innovative new tools, models and ideas for building a bright green future. We don't do negative reviews – why waste your time with what doesn't work? We don't offer critiques or exposes, except to the extent that such information may be necessary for the general reader to apprehend the usefulness of a particular tool or resource. We don't generally offer links to resources which are about problems and not solutions, unless the resource is so insightful that its very existence is a step towards a solution. We pay special attention to tools, ideas and models that may have been overlooked in the mass media. We make a point of showing ways in which seemingly unconnected resources link together to form a toolkit for changing the world.
