Natural gas has long been considered a more climate-friendly alternative to coal, as gas-fired power plants generally release less carbon dioxide into the atmosphere than their coal-fired counterparts. But a new study finds that when the full impact of the industry is taken into account, natural gas could contribute as much as coal to climate change.
Natural gas is primarily composed of methane, a potent greenhouse gas. A new peer-reviewed analysis in the journal Environmental Research Letters finds that when even small amounts of methane escape from natural gas wells, production facilities and pipelines, it can drive up the industry's emissions to equal the effects of coal.
