Countries in the region examine ways to lead a greener lifestyle, reports Karl Wilson in Sydney.

The carbon tax has become one of the most politically divisive and bitterly fought tax reforms of this century and governments around the world, and in particular Asia, are debating the issue.

In an attempt to cut carbon emissions and reduce the effects of global warming, many countries are implementing green growth policies and introducing reforms to reduce dependence on fossil fuels.

On July 1, Australia will introduce a carbon tax. India already has a nationwide carbon tax of 50 rupees (90 US cents) per metric ton on coal.

Since the devastating earthquake and tsunami that hit Japan in March 2011 and the subsequent environmental disaster at the Fukushima nuclear power plant, Tokyo has been reassessing its entire energy policy.

South Korea has made low carbon, green growth a national priority while countries such as Malaysia, Singapore, Vietnam and Thailand are all pursuing their own policy objectives.

A new report by the United Nations Economic and Social Commission (ESCAP) for Asia and the Pacific is recommending that developing Asia-Pacific countries introduce a $10 a ton carbon dioxide tax on major greenhouse emission polluters, such as coal-fired power stations.

It is expected that many governments will wait and see what impact Australia's carbon tax has before making any firm decision.

The controversial tax has divided Australia since its proposal. When it comes into effect next month, around 500 of the country's biggest emitters of carbon pollution (carbon dioxide, methane, nitrous oxide and fluorocarbons from aluminum smelting) will be required to pay, via a permit system, a tax of A$23 ($22.60) on every ton of carbon dioxide released into the atmosphere.

The tax is believed to be the highest in the world - much higher than Europe, where it ranges from $8.70 to $12.60, according to a BBC report.

Industries that will be most affected by the Australian tax include electricity generation, stationary energy production, mining, business transport, waste and industrial processing.

Increasing power bills

Australia's federal opposition leader, Tony Abbott, has said repeatedly that the tax will increase consumers' power bills and cost jobs, especially in the coal mining and electricity industries.

Abbot has called the tax "economic madness" and has vowed to repeal the legislation if elected in polls due next year.

"It's a tax increase pretending to be an environmental policy," he said.
