The start of the 2009 United Nations Climate Change Conference in Copenhagen this week seems like a good time to look at some of the posters produced on the subject. These are from Good 50×70 (aka Good Amsterdam), a nonprofit initiative aimed at promoting the value of social communication in the creative community, inspiring the public via graphic design, and giving select charities a database of communication tools they can use in their campaigns. Good 50×70 hosts an annual online contest inviting designers to create posters on seven critical global issues, as described in briefs by seven charities. The best 30 responses in each category as chosen by a distinguished jury are cataloged and exhibited worldwide. Here is a sampling of Climate Change posters produced from the brief provided by the World Wildlife Fund.
