Require all point of sale stations to introduce a 'print receipt' option.
Why is this important?
Only a very small % of receipts are required by consumers, the vast majority are thrown straight in the bin either by the cashier or the consumer. This is a huge waste of paper not to mention all the other resources that are required for production and distribution of these receipt rolls. Requiring a simple prompt to find out whether the consumer wants a receipt printed is a common sense way to reduce our collective waste.
