Labor and a prominent think-tank have rejected climate policy modelling which paints emissions targets as damaging for the economy.
The modelling, authored by Brian Fisher from BAEconomics, says Labor's 45 per cent emissions reduction target would cause more than 300,000 job losses as well as drop wages by eight per cent.
Labor's climate and energy spokesman Mark Butler says the modelling released on Tuesday is at odds with other analysis, labelling it as "complete rubbish".
