The welsh thing is complete greenwash.
Ask yourself this. How much does a carrier bag weigh? Well my nice JS Orange ones come in at 5g on my scales. So I would need approx 200 to weigh a kilo.
Now we all know that carrier bags are made from the same stuff as petrol, oil…lovely sticky black stuff.
Now petrol has a specific gravity of approx .74 so a kilo of fuel will get you 1.35 litres.
Assuming you have an average car, lets say 40mpg, then that 1.35 litres is going to get you 12.1miles or 19.4km if you are under 30 years old.
So remember that that 1.35litres of fuel could have made 200 carrier bags. Thats 200 carrier bags for every 19.4km you drive.
To put it another way you car uses the equivalent of one carrierbag for every 100m you drive the **** thing!
Charging for carrier bags is greenwash at its worst. Until we stop sucking up huge amounts of stored dinosaur juice and wasting it on stuff then we really are wasting our time.
Give me free carrier bags, and let me drive a little less as a result
