Drivers could be hit with a carbon tax to tackle global warming, according to Lord Smith, the former culture secretary speaking at the Environment Agency’s annual conference.
He wants to see personal carbon allowances for individuals to cut greenhouse gases by penalising people for using too much fuel.
Every time someone used their car, took a flight or turned their central heating on, their personal allowance would go down. If it hit zero, they would have to pay to get more carbon credits.
Individuals would gain credits by turning to walking or cycling instead of opting to use their car.
