The Motor Industry Association is already voicing concerns over proposed new policies to encourage motorists to go green.

The government wants a Clean Car Standard to improve fuel efficiency and a Clean Car Discount, funded by fees on high-emission vehicles.

But Motor Industry Association chief executive David Crawford told Andrew Dickens he can hear alarm bells already.

“It will be a very lumpy entry. People will be looking to take advantage of the rules before and after the introduction of this Clean Car Discount . All this will do is force the price of vehicles up.”

The move would shave up to $8000 off fuel efficient vehicles, while penalising owners of gas guzzlers as much as $3000.
