Exported gas produces far worse emissions than coal, major study finds

Exported gas emits far more greenhouse gas emissions than coal, despite fossil-fuel industry claims it is a cleaner alternative, according to a major new research paper that challenges the controversial yet rapid expansion of gas exports from the US to Europe and Asia.

Coal is the dirtiest of fossil fuels when combusted for energy, with oil and gas producers for years promoting cleaner-burning gas as a “bridge” fuel and even a “climate solution” amid a glut of new liquefied natural gas (or LNG) terminals, primarily in the US.

But the research, which itself has become enmeshed in a political argument in the US, has concluded that LNG is 33% worse in terms of planet-heating emissions over a 20-year period compared with coal.

“The idea that coal is worse for the climate is mistaken – LNG has a larger greenhouse gas footprint than any other fuel,” said Robert Howarth, an environmental scientist at Cornell University and author of the new paper.

The US is the world's largest LNG exporter, with multiple new export terminals under construction.

1. Makes sense

NG is ‘cleaner’ to burn, but from a CO2 standpoint, a mulligan. And with all the energy inputs required for producing/shipping LNG, not surprising.

Been wondering about the leakage with all this new production, Methane being 10x more potent GHG relative to CO2 over the short run.
