For most countries around the world, sourcing energy entirely from wind, solar, geothermal, and hydropower by 2050 would reduce their energy needs and costs, improve air quality, and help slow climate change, according to a study in Environmental Science & Technology.
how can you prove this?
Here you go! https://www.independent.co.uk/life-style/health-and-families/veganism-environmental-impact-planet-reduced-plant-based-diet-humans-study-a8378631.html
That’s the opinion of one of the authors of the study. it is not a substantiated by the study itself.
Its not just one. This is pretty common knowledge among people in their field. These are specialists in their field, their opinions don’t just come from nothing, they are informed by information from the studies.

your first link doesn’t speak to your claim at all. your second link depends on the same author.
Here’s a link to the research article itself with all the data from which they drew their conclusion: https://josephpoore.com/Science 360 6392 987 - Accepted Manuscript.pdf
they are misusing the LCA data. since it was gathered through disparate methodologies, it can’t be combined as they have done.
edit: regardless, this paper doesn’t support the claim you made.
They aren’t, but I don’t feel like going into it with you. I will use a simpler data-point to prove that my initial claim was correct.
Livestock and their byproducts account for at least 32,000 million tons of carbon dioxide (CO2) per year, or 51% of all worldwide greenhouse gas emissions. If everyone went vegan, that would remove the majority of greenhouse gas production. So put simply, it would be the “biggest” thing everyone could do to reduce CO2 emissions.(That is just CO2, there are many other horrible things related to animal agriculture.)

your article makes a claim unsubstatiated by the paper itself. and the paper is almost 2 decades old, and does not, itself, make any claim about the best way for anyone to reduce their GHGe.
they are. their reference papers state this explicitly
This is just false. The biggest source has long been fossil fuel burning, not agriculture, and that remains true even when you include fossil fuel use by agriculture.
On top of that, meat and dairy are only part of agriculture; a big chunk of methane emissions from agriculture come from rice farming.
A huge cut in meat (and dairy) consumption is going to be needed to get to net zero emissions, but it’s not a majority of what is needed. People recommend it strongly in large part because ending meat consumption doesn’t cost people money, so everybody can do it.
Please don’t repeat false claims here.
there is no causal mechanism by which anyone going vegan reduces any ghg production
that’s simply not true. GHGe for all of agriculture come out to about 20% of total GHGe.
