National Geographic’s Green Guide, which the National Geographic Society acquired in 2007 and relaunched as a general consumer quarterly in March, has been shuttered, FOLIO: has learned.

A source close the magazine said the company is “discontinuing” the magazine but "may publish some print specials.” Instead, the focus will be on the Green Guide’s Web site [1], which launched in 2002.

It is unclear how many employees will be affected by the shift, or when the decision will be announced. (The masthead lists 16 staffers.) A spokesperson for National Geographic declined to comment on the change.

Touted as a magazine "written for general consumers, not for enviromaniacs,” the Green Guide carried a rate base of 100,000 and a $4.95 newsstand price, with distribution at Barnes & Noble, Whole Foods Markets and Hudson News. The magazine was printed on Forest Stewardship Council-certified paper.

National Geographic also produced a digital edition of the magazine, which is expected to be published through at least next fall. A mobile version of the guide is slated to roll out this month.
