From what I read in the article, its true that natural gas burns with fewer CO2 emissions than coal or oil. However, over a 20 year timeframe natural gas production, distribution, and consumption produces more methane than than either oil or coal. Since methane is a more powerful greenhouse gas, the increased emission of it, surpasses any benefit from fewer CO2 emissions.
