The issue was well known but little studied: methane does not hang around in the atmosphere for long, so scientists had assumed that the odd leak would not undermine
its use as a bridge fuel.
However, in their recent publication in Climatic Change Letters, Howarth et al. (2011) report that their life - cycle evaluation of shale gas drilling suggests that shale gas has a larger GHG footprint than coal and that this larger footprint «undercuts the logic of
its use as a bridging fuel over the coming decades».
«The large GHG footprint of shale gas undercuts the logic of
its use as a bridging fuel over coming decades, if the goal is to reduce global warming.»

as natural gas to reach renewable energy goals.
Some scientists, including Cornell University environmental biologist Robert Howarth, have questioned natural gas's
use as a «
bridge fuel» because producing the gas, most of which is released from underground shale formations through hydraulic fracturing, often emits a lot of methane, a potent greenhouse gas.

Using this new information

as other independent studies on methane emissions published since 2011, and the latest information on the climate influence of methane compared to carbon dioxide from the latest synthesis report from the Intergovernmental Panel on Climate Change released in September of this year, it is clear that natural gas is no
bridge fuel.
In addition, the popularity of natural gas relies, in part, on its reputation
as a «
bridge fuel» — the fossil

bridging fuel to slow global warming over the next few decades — with a particular focus on China.
One of CSPW's major criticisms of the QER under President Obama was its treatment of natural gas
as a «
bridge fuel» to a renewable energy future; since the infrastructure
used to extract, process, and transport natural gas to market is essentially the same
as that for oil and petroleum products, continued reliance on natural gas only delays the transition to clean, renewable energy and has only marginal CO2 - reduction benefits in the near term.
