Why We Need a Carbon Tax III. Natural Gas Is Not a Real Solution

 

Most people agree that global warming is for real and that it is caused by a buildup of greenhouse gases in the atmosphere, mostly from carbon dioxide.  We need to respond to this existential threat and the U.S. should lead the way.  The Environmental Protection Agency’s new regulations call for a 30% reduction in carbon emissions, from 2005 levels, by 2030.  Since fracking has led to a natural gas boom in the U.S. and the burning of natural gas only emits half as much carbon as the burning of coal, it is very likely that the new EPA rules will lead to a major replacement of coal by natural gas in U.S. energy production.
CaptureBut there is a downside to this approach as pointed out in yesterday’s New York Times, “The Potential Downside of Natural Gas,” as follows:

  • Natural gas is starting to replace nuclear power which has no carbon footprint. Last year five reactors announced that they would close because of the low cost of natural gas. This will increase CO2 in the atmosphere.
  • Fracking for oil produces natural gas as a side product which may not be easily marketable. This excess natural gas is either burned off or escapes unburned releasing methane which causes even more damage than CO2.
  • The low cost of natural gas is also slowing down the development of renewable energy sources such as wind and solar power.

A far more efficient system of reducing carbon dioxide in the atmosphere would be to tax its emission from any fuel source.  The most commonly mentioned amount is $20 per ton which would raise the price of gasoline by about 10 cents per gallon.   This way the use of all forms of fuel, including coal, oil and gas, would be taxed equally based on how much carbon they emit.  This would create a huge economic incentive for developing carbon capture in fuel combustion, which is the ultimate solution to eliminating CO2 emissions.
In other words, we have a huge problem on our hands which needs an effective solution.  Half measures will not get the job done and will just cause lots of confusion and political controversy in the meantime.  It’s time for some real leadership!
