CANBERRA (Reuters) - Australia unveiled plans on Sunday to slap a carbon tax of A$23 a tonne on its 500 worst polluters from 2012, sweetened by tax cuts for voters fearing higher energy bills, and paved the way for the largest emissions-trading scheme outside Europe.
Prime Minister Julia Gillard said steel and aluminum manufacturers and other polluters would pay a A$23 ($24.70) price rising by 2.5 percent a year, before the minority government moved to a controversial market-based emissions scheme in mid-2015.
