Design Can Change (designcanchange.org) is a project created by designers that believe that positive change can happen by working together. The website is slick (sometimes annoyingly so) however the message is good.
Take the Design Can Change pledge:
In my professional practice, I will endeavor to: Learn, Think, Act, Inform, Unite.
Learn: Engage in the topic and seek to understand the issues
Think: Make a sustainable mindset second nature
Act: Put my knowledge to use in my daily work
Inform: Share information and build awareness for sustainability
Unite: Spark change through collective strength
