£100 off your council tax bill - only for volunteers

Local Libraries Face Closure As Government Cuts Bite
Local Libraries Face Closure As Government Cuts Bite

There could be £100 knocked off the annual council tax bill for community volunteers if a new proposal is taken up by the Coalition. The Local Government Association (LGA) is calling for a £50m fund to offer half a million community volunteers 10% off their council tax - in recognition of their work.

Is this a genuine move to recognise community service? Or is more about getting valued public work to be carried out on the cheap?
