Methane is a powerful greenhouse gas , 80 times more potent at warming the atmosphere than carbon dioxide. In 2014, a California law required statewide methane emissions to be cut by 40 percent by 2030 from 2013 levels. Currently, the local natural gas utility estimates that methane emissions in the Los Angeles area are decreasing at a rate of about 5.8 percent per year. However, a new Caltech study shows that methane emissions in the region are decreasing at a much slower pace: 1.6 percent per year over the past decade.
