Excerpt From the telegraph:
Encouraging motorists to trade in their petrol cars for diesel vehicles was one of the last Labour government’s biggest environmental mistakes.
Barry Gardiner, the shadow Environment minister, said the party was trying to cut CO2 emissions when it introduced new vehicle tax rates in 2001.
It meant that motorists switched to diesel vehicles and parts of the country saw a big increase in nitrogen dioxide and other harmful chemicals in the atmosphere.
Mr Gardiner said: “Hands up — there's absolutely no question that the decision we took was the wrong decision.
Gordon Brown, who at the time was the Chancellor of the Exchquer, announced in 1998 that “diesel cars should attract less vehicle tax than their petrol equivalents because of their better CO2 performance”.
In 2001, when Mr Brown reduced vehicle tax for all cars with low CO2 emissions, giving company car buyers, responsible for half of new purchases, an incentive to switch to diesel.
Motoring groups warned that new levies would hit drivers already struggling to cope with high prices at the pumps and lower the resale value of diesel vehicles.
