Tried here in Australia.

Stores went from giving out free bags to selling "reusable" bags. What was a negative has now become a $5m per annum cost saving.

The "reusable" bags fill our rubbish bins.

For every bag not picked up in the weekly shop plastic garbage bags have been sold.

Funding for plastic like bags made from recyclable materials like hemp and wheat has dried up.

Net result: Increased plastic waste in the environment, increased use of non-biodegradable plastics, increased costs to consumers.

A total failure on all fronts, like so many ill thought out environmental programs
