I don't mean to be cynical but saving the planet will - as ever - make the rich richer and the poor poorer. In Ireland some years ago people were urged to use less electricity; they complied. And the result? The electricity companies earned less money so they put up the unit price to return their income to the previous value. So eventually customers were paying more for less!
Some highly educated idiot recently suggested that supermarkets should charge shoppers to park in their car parks and use the resulting income to pay for home deliveries. Result? When this income has dropped because very few customers park anymore, we'll all have to pay for home deliveries ... and take a day off work waiting for them to arrive. The supermarkets will sell of the car park land. Result: rich,richer and poor, poorer. Lots of lorries too.
