local currency

See Emissions Reduction Currency System for community based initiatives aimed at emission reduction In economics, a local currency, in its common usage, is a currency not backed by a national government (and not necessarily legal tender), and intended to trade only in a particular area. As a tool of fiscal localism, local moneys can raise awareness of the state of the local economy, especially among those who may be unfamiliar or uncomfortable with traditional bartering. They encompass a wide range of forms, both physically and financially, and often are associated with a particular economic discourse.
