Greens propose tax on sugary drinks

SUGARY drinks could cost 20% more under a Greens' policy to tax sugar in sweetened beverages to raise $2 billion over four years.

The Greens' proposal would put a 20% tax on sugary drinks as part of the minor party's broader strategy to cut obesity rates.

Party leader Richard Di Natale said 30% of the average child's added sugar intake came from soft drinks, and a tax could help reduce consumption of such drinks by up to 12%.

He said the tax would raise about $500 million a year, which the Greens would invest in health initiatives.

"The sweetest part of this policy will be the longer term benefits to Australians by reducing chronic disease and achieving better health outcomes," Senator Di Natale said.
