The last paragraph in the article “Study: Global Warming Methane Exceeds Government’s Estimates” (Feb. 14) is misleading. The claim that the use of compressed natural gas for vehicles does not help slow global warming is the wrong answer to the wrong question. The use of CNG in vehicles will improve air quality by reducing carbon dioxide, nitrogen oxide and particulate emissions. It will also help the United States to be less dependent on petroleum by reducing the amount of diesel and gasoline fuel used by vehicles. Approximately 90 percent of petroleum imports are used for vehicle fuel.

The switch to CNG also makes economic sense. For the first time in 50 years, the natural gas spot price at the Columbia Gas Transmission (TCO) trading point in southwestern Pennsylvania is forecasted to be below the benchmark Henry Hub price.
