Industrial methane emissions are 100 times higher than reported, researchers say

This article discusses research that shows that industrial methane emissions are 100 times higher than reported.

Emissions of methane from the industrial sector have been vastly underestimated, researchers from Cornell and Environmental Defense Fund have found.

Using a Google Street View car equipped with a high-precision methane sensor, the researchers discovered that methane emissions from ammonia fertilizer plants were 100 times higher than the fertilizer industry’s self-reported estimate. They also were substantially higher than the Environmental Protection Agency (EPA) estimate for all industrial processes in the United States.

The researchers’ findings are reported in “Estimation of Methane Emissions From the U.S. Ammonia Fertilizer Industry Using a Mobile Sensing Approach,” published May 28 in Elementa. The work was funded in part by a grant from the Atkinson Center for a Sustainable Future’s joint research program with EDF.
