Emily Gertz is a freelance journalist covering the environment, science and technology. She has written for Grist, Dwell magazine, Popular Mechanics online, Scientific American online, and more.

Gertz is currently the editor and lead blogger of the "Stop Global Warming" blog at Change.org. At South by Southwest Interactive 2009, Gertz joined prominent "green" bloggers Jon Lebkowsky of Social Web Strategies, John McElhenney of Clear Green Technologies, and Rob Reed of maxgladwell.com, in a discussion on social media and sustainability.

Gertz was among the founding bloggers of Worldchanging.com, the award-winning web site reporting on ideas, tools and other signs of progress toward a sustainable world, as well as the site's interim managing editor during the latter half of 2007. She contributed several sections to the book Worldchanging: A User's Guide for the 21st Century (Harry N. Abrams 2006), which BusinessWeek called "a smart, hip mini-encyclopedia of what's new and what's next in green technologies and earth-conscious ideas." And her 2005 Grist article "Naughty by Nature: Ever thought about the toxins in your sex toys?" was excerpted at length in Grist's 2007 book, Wake Up and Smell the Planet.

Gertz adopted online journalism early on: In the late 1990's, she was the producer for environmental and outdoors news for OregonLive.com, the web site of The Oregonian newspaper.  Prior, she was a producer for over two years with IGC.org, founder of five news and information networks devoted to the environment, women's rights, labor, and other issues.

Gertz also has over a decade's experience in online user experience, content strategy and social media. She has consulted with diverse clients including non-profits, financial institutions and consumer products companies, and has often worked as a web producer and site manager. Gertz is a member of the National Association of Science Writers, and of the Society of Environmental Journalists, where she is a member of the group's Freedom of Information Task Force.
