Green Patriot Posters is a messaging campaign centred on posters that encourage all U.S. citizens to take part in building a sustainable economy. We have commissioned posters from design leaders, and developed an on-line community for sharing and voting on original designs. The favourites will be distributed through multiple channels (print, web, bus ads, licensing, etc.) to reach the widest audience possible. Green Patriot posters display an image of strength, optimism and unity. Some focus on specific actions that anyone can take; some are general. The overriding message is that our individual actions do matter, that we can all be part of the sustainability movement, and that this can become a defining value of 21st Century patriotism.
