U.S. Study Suggests Carbon Prices Soil Consumption

To measure emissions of a country greenhouse gas emissions from fossil fuels, it is logical to consider the carbon chain, from mine oil or coal to a consumer display, researchers reported Monday.

At the time, set a price on climate warming carbon dioxide generated oil, coal, natural gas and other fossil fuels, in particular, through which fuel is burned.

This may not be the most effective way to calculate carbon 'costs, the researchers wrote in the journal Proceedings of the National Academy of Sciences.

Of carbon dioxide generated by human activities, such as coal, power plants and factories, and oil-powered vehicles to promote the heat-trapping greenhouse effect that contributes to climate change. Remedy this situation, the impact, some leaders say the agreed price for carbon emissions to limit consumption.

Without the benefit of any method of charging carbon dioxide, the researchers suggest that a practical matter, it might be the more effective management of a so-called "carbon tax" for the input.

"We exceeded by trying to place blame, because it's just an argument that will never be won," said co-author Steven Davis, of the Carnegie Institution of Washington. "The only way it will never return to normal is if we can come up with something resembling a coherent, inevitable price on carbon that apply globally, and the chips will fall as they can. "

The researchers analyzed the extraction of fossil fuels, combustion and consumption in 112 countries and 58 industries. They learned that 51 percent of all emissions of carbon dioxide from human activities that resulted from fossil fuels, or products that have been sent across borders to reach consumers.

Drillers incentive BIG and miners

They found that 67 percent of global emissions of carbon dioxide would be if the adjustment of the extraction of fossil fuels has been done in China, the United States, the Middle East, Russia, Canada, Australia and India.

Countries that did not participate would lose revenue from the carbon tax linked to the supply chain, the authors found.

To give an incentive to the main exhaust of fossil fuels, such as Saudi Arabia, to put a tax on oil to reduce oil demand should be clear that the tax should be imposed, somewhere along the Davis said by telephone line in the state of Washington.

"If this oil should be taxed when it was burned elsewhere, such as the United States, so that the Saudis prefer to administer and collect tax revenue they could use at home rather than provide revenue to be collected in the United States, "Davis said.

Put a carbon tax at the time of extraction would be effective because there are far fewer coal mines and oil wells that there are factories and power plants, which could prevent the relocation of companies that can occur if adjustment took place where the fuel was burned, the authors write.

They also found that most of the world's fossil fuels eventually exported in developed countries, which also import many products depend on fossil fuels. China is the exception to this trend.
