Yeah that study is probably “true” but very myopic. I believe I commented on this the last time it was posted.

Sure, total co2/ch4 emissions is likely higher. Liquefying and transporting LNG isn’t energy free, while coal is typically burned closer to where it’s mined. I get that’s probably the tact they’re trying to take, fossil fuel still bad and don’t let LNG get too greenwashed.

HOWEVER. The study and article seems to intentionally completely ignore all the secondary emissions of coal. Tallying “emissions” for a picture of true environmental impact is way way way more than just X tons of co2. Burned coal creates a massive amount of atmospheric ash and particulate that is chock full of heavy metals, literal radioactivity, and sulfur/nox that generates acid rain. The tailings from mining and the fly ash from burning is also incredibly toxic and destroys all groundwater for miles and miles around it. It’s just one huge bad flaming lump of cancer that sanitizes entire ecosystems and reduces life expectancy by multiple decades in places where it is heavily used.

Natural gas generates none of this, with the exception of fracking groundwater problems (which, is admittedly a problem, but still way less concentrated than the previously mentioned). A fuel stock of >95% CH4 with the remainder made up of water and longer chain hydrocarbons emits nothing but CO2 and water vapor. Also, combined cycle gas power plants have some of the highest end to end thermal efficiencies of any power plant ever built, which is another huge plus over coal.

So no, it’s not perfect, and its still “bad”. but it is doing a fucking bang good job of not giving people cancer and getting a dirty 18th century energy source out of our modern society where it does not belong.
