Republican Party Officially Embraces ‘Garbage’ Agenda 21 Conspiracy Theories As Its National Platform By Stephen Lacey on Aug 15, 2012 at 2:08 pm If you want to understand just how extreme and conspiratorial many in the “mainstream” Republican party have become, look no further than a resolution on Agenda 21 passed quietly in January. Agenda 21 is a completely non-binding international framework for sustainability passed in 1992 at the Rio Earth Summit. The framework, which sets out very loose aspirational goals for making communities more efficient and less carbon-intensive, was signed by then President George H.W. Bush and later upheld by Presidents Bill Clinton and President George W. Bush.
