Every adult should be forced to use a 'carbon ration card' when they pay for petrol, airline tickets or household energy, MPs say.
The influential Environmental Audit Committee says a personal carbon trading scheme is the best and fairest way of cutting Britain's CO2 emissions without penalising the poor.
Under the scheme, everyone would be given an annual carbon allowance to use when buying oil, gas, electricity and flights.
Anyone who exceeds their entitlement would have to buy top-up credits from individuals who haven't used up their allowance. The amount paid would be driven by market forces and the deal done through a specialist company.
MPs, led by Tory Tim Yeo, say the scheme could be more effective at cutting greenhouse gas emissions than green taxes.
The Labour government doesn't oppose the idea in principle, either; it merely "warns it is 'ahead of its time'." Every purchase would be monitored and incorporated into this scheme, the news report says. George Monbiot, who is currently advocating a "citizen's arrest" of John Bolton, praises the measure's redistributionism: it "tends to redistribute wealth from the rich to the poor."
Some point out the difficulties of the program:
But critics say the idea is deeply flawed. The scheme would penalise those living in the countryside who were dependent on their cars, as well as the elderly or housebound who need to heat their homes in the day.
Large families would suffer, as would those working at nights when little public transport is available.
It would need to take into account the size of families, and their ages. There is huge potential for fraud.
Matthew Elliott of the Taxpayers' Alliance said the cards would be hugely unpopular. 'The Government has shown itself incapable of managing any huge, complex IT system.' he said.
Some are also criticizing this matter more broadly in principle, saying that it would offer too extensive an intervention into the economic lives of its citizens, and some are even calling it "totalitarian." Tim Yeo has a long history of advocating further government intervention in the daily lives of its citizens. For example, last year, he argued that the UK government should work to abolish domestic flights.
Will David Cameron and the other Conservatives also support this plan? Some think they will not.
