Study: Natural Gas Expansion Will Raise Emissions, Worsen Climate
Increased reliance on so-called 'bridge fuel' will worsen climate crisis by delaying shift to carbon-free renewable energy, research warns

A national shift to natural gas for power generation is no panacea for the climate crisis, new research finds.
In fact the study, published on Wednesday in the journal Environmental Research Letters, finds that treating natural gas as a so-called "bridge fuel" could actually make global warming worse by delaying the shift to carbon-free, renewable energy sources.
The study was undertaken by researchers from the University of California, Irvine and Stanford University and funded by the nonprofit organization Near Zero. The scientists asked experts for their estimates of natural gas supply curves, explained Dr. Christine Shearer, a post-doctoral researcher at the University of California-Irvine, in a video abstract of the article. The researchers then input this data into an energy economic model to assess different future scenarios of natural gas production against varying potential climate policies, including: no climate policy, a moderate tax on carbon, and a "stringent" tax on carbon.
"We found that the increased use of natural gas for electricity will not significantly lower emissions, because gas competes not just with coal, but also with lower carbon sources of electricity such as renewables," said Shearer. "If we want to lower emissions and decarbonize the electricity sector, our studies and others suggest we need a price or cap on carbon."
In the video, Shearer concludes that "the biggest driver of emissions reductions" is the strength of the climate policies put in place.
