Liquified natural gas leaves a greenhouse gas footprint that is 33% worse than coal, when processing and shipping are taken into account, according to a new Cornell study.
It hard to see this as anything other than a bad faith comparison.
It compares trans-oceanic LNG vs. US domestic coal
It makes a lot of assumptions about inefficient and leaky extraction, processing, and transport approaches
It only considers CO2 and methane ignoring other ways that LNG is far cleaner than coal
It is important to consider the entire life cycle of LNG, but a more even-handed author would conclude we should address these inefficiencies (e.g. via regulation), rather than fixating on promoting coal.
