Under a controversial plan passed in the Australian parliament, Australia’s 500 biggest greenhouse gas emitters
will pay $23* for every ton of carbon they emit. The carbon pricing scheme, which will go into effect next July after the Senate’s likely nod in November, has been a political hot button for the Australian government and for prime minister Julia Gillard.

Even though packed with “sweeteners” that pull in political support but dampen its likely effect, the bill is considered by many as a huge step for Australia, the world’s largest exporter of coal and a top leader in greenhouse gas emissions per capita.

The Government estimates the carbon price will cost Australian households an additional $10 per week. But the bill passed today will also return more than half of the revenue raised to people via tax credits and direct payments, producing payments to individuals and households that should be more than enough to cover rising commodity and energy prices.

By making burning fossil fuels more expensive and thereby encouraging efficiency, efficient technologies and renewables, the bill, according to Labor estimates, will reduce Australia’s carbon emissions by 159 million tons by 2020, cutting at least 5 percent from the country’s emissions by 2020.
