The chair of the UK's Environmental Audit Committee, Tim Yeo, says a personal carbon allowance is the best way to cut CO2 without hurting the poor, Treehugger reports.
If individuals go over their allowance they would have to buy credits from somebody else.
"We found that personal carbon trading has real potential to engage the population in the fight against climate change and to achieve significant emissions reductions in a progressive way," he said. "The idea is a radical one. As such it inevitably faces some significant challenges in its development. It is important to meet these challenges."
During the 1973 energy crisis in the U.S., gas ration stamps were printed, but never used.
