More than 190 countries will gather at the UN Climate Change Conference this December 7-18 in Copenhagen to determine the environmental fate of our planet (see the Guardian's ongoing coverage for baseline facts). With less than 40 days remaining before the Copenhagen conference, a new effort -- Hopenhagen -- seeks to unite citizens across the world in political action.

The Hopenhagen site features a petition, which will be delivered to the conference. The goal: Get participating countries to seal the deal and sign an effective climate pact.

There is a mandatory Hopenhagen Facebook fan page. In one of the more interesting Facebook applications I have seen in a while, the Hopenhagen app seeks to create word of mouth engagement by giving people a Passport to Hopenhagen. To get passport points one must agree to tell friends or participate in sustainable activities (all of which are conveniently posted to your wall).

I like this app because it shows people some of the activities they can engage in to make their own contribution to the environment. Gaming and education will become an increasingly important part of the sustainability and general environmental movement. Most citizens don't understand how their own carbon footprint affects energy demand. So more and more applications like this one and sites like Chevron's willyoujoinus.com will endeavor to educate the general public and change citizen behavior.

Self described as a movement, Hopenhagen was created with the support of numerous corporate partners. The site lists other environmental campaigns such as 350 that interested parties can engage in.
Hopenhagen is also on Twitter. Get on board today and spread the hope!
