One of the most discussed methods of counteracting global warming is to limit carbon and charge carbon emissions for investments in carbon-absorbing technologies. Planting new trees with the money raised is a frequently mentioned solution, the effectiveness of which still needs to be proven.
But how much will such an approach cost per tonne of carbon dioxide (CO2) emissions? How will this affect the global economy? The numbers are slowly growing.
A United Nations report published in May 2007 estimates that global efforts to reduce greenhouse gas emissions, such as carbon dioxide, could cost the world economy 3% of total production by 2030. That is, by 2030 World economic output could be 3% lower than it would otherwise be due to the cost of carbon pollution control programs.
According to the World Resources Institute, an environmental think tank in Washington to reduce carbon levels to the level proposed in the UN report will cost between $ 20 and $ 100 per tonne of carbon dioxide.
McKinsey & Co., an energy consulting firm, estimates that to reach the level of greenhouse gases by 2030, recommended by a UN study, will cost $ 40 per tonne of CO2.
In Europe, where “carbon trading” has become a new buoyant specialty “derivatives trading”, as of May 2007, the price of a ton of CO2 will cost $ 25. That’s how much it would cost you today to emit a ton of CO2 next year.
Duke Energy Corporation of Charlotte, North Carolina, uses a figure of “$ 7.50 to $ 30 per tonne of CO2” in future investment plans.
Another study is given by Professor Robert Sokolov of Princeton University, who was quoted by the Wall Street Journal as saying that a carbon cap that would result in a $ 30 fee per tonne of CO2 emissions would also cost American consumers an extra 30 cents. liter on the gas pump.
Thus, estimates still range from $ 20 to $ 100 per tonne of CO2 emissions, creating many opportunities for politicians and economists to constantly change alternative plans, giving affected consumers a reason to scratch their heads.
The way it looks now, not only science and politics, but the economics of global warming also looks equally complex.
