Personal carbon quotas considered
From the page:
Plans to limit energy use by giving everyone an individual carbon allowance are being considered by the government.
The plan would see people issued carbon units – each equivalent to 1kg of greenhouse gases – to use when buying products such as flights and petrol. The scheme would see people and businesses able to buy or sell extra rations.
……………. If this ever comes off it might have an effect on emissions. I would anticipate a lot of resistance to the idea of rationing though.
