Slate Launches Green Challenge To Reduce Carbon Emissions

(Arlington VA - October 23, 2006) – Slate, the online magazine, today announced Slate’s Green Challenge on Slate.com. For the next eight weeks, Slate, in collaboration with the eco-Web site TreeHugger.com, invites each American to consider his or her own contribution to global warming, and challenges the public to go on a carbon diet. The goal is to reduce the amount of carbon dioxide that individuals put into the atmosphere by 20 percent.

Each week of the Green Challenge opens with a short quiz, and points to a series of "action items" for reducing individual carbon output. Once participants have registered, Slate will monitor individual progress in losing carbon poundage and collective poundage lost by individuals taking the challenge. Those who miss the launch date may start at any point by taking the initial quiz. The first 500 people to complete the challenge will receive a free Slate/TreeHugger Green Challenge t-shirt from I’m Organic (www.imorganic.com).

“As the holidays approach, many of us think about diets, past and future, and the costs and inevitably painful consequences associated with excess,” said Jacob Weisberg, Slate editor. “The Slate Green Challenge is a diet that anyone can stick to painlessly, while seeing quick and satisfying results. We’re delighted to partner with TreeHugger in this innovative and positive campaign.”

“The Green Challenge is our way of showing the world that a sustainable decrease in toxic carbon emissions is accessible and relevant to everyone,” said Graham Hill, founder of TreeHugger. “Our goal is not to scare or pontificate, but to educate and engage.”
