Natural gas is widely promoted as a bridge fuel which allows society to continue to use fossil fuels while reducing greenhouse gas emissions. Here, we review recent research on the greenhouse gas footprint of natural gas (conventional gas and shale gas), focusing on methane emissions.
When methane emissions are included, the greenhouse gas footprint of natural gas is larger than that of other fossil fuels, particularly when methane and carbon dioxide are compared over the decadal time scale. Shale gas has higher emissions than conventional gas.
To date, most studies on methane emissions from natural gas have relied on poorly documented and limited information from industry. Far more study by independent scientists is required.
