Georgia conservatives who rallied opposition to the T-SPLOST have embarked on a new mission: taking on the United Nations.

Because behind the penny-tax referendum, which would have created a regional transportation system, and underpinning many plans labeled “sustainable development,” they say, is a U.N. initiative called Agenda 21. Created in 1992, the plan promotes the concepts of smart growth.

But if fully implemented, some critics say, it could usurp private property rights, herd people into city centers, and use regionalism as a stepping stone to a single world government. Many believe that warnings about climate change are a scam designed to bait people into accepting Agenda 21’s sustainable-development principles.

Agenda 21 is showing up in subtle ways within local, county and even state governments, leaders from the Georgia Leadership Coalition told members at their Sept. 29 meeting in Smyrna. The GLC — which as the Transportation Leadership Coalition helped sink the T-SPLOST — is working to educate its members about the plan so that they can identify it within their local governments.

A story in today's Atlanta Journal-Constitution explores examples of what the GLC says is Agenda 21 at work locally, and how the theory is gaining traction. Subscribers can read the full story in today's edition of the Atlanta Journal-Constitution or on the AJC's iPad app. Subscribe today.
