The Sierra Club said Energy Department steps to reduce methane emissions tied to the natural gas sector are vital tools in the fight against climate change. U.S. Energy Secretary Ernest Moniz unveiled ways to minimize the amount of emissions generated from the natural gas sector.

Critics of hydraulic fracturing, known also as fracking, say the process could lead to higher emissions of methane, which could in part offset the low-carbon footprint of natural gas. Moniz unveiled a four-point plan for what he said […]
