Methane release varies by animal type: https://reporter.anu.edu.au/all-stories/kangaroos-the-soluti...

That meat gets eaten and largely turned into poo and gas (as byproduct of using up that stored energy), yeah? You're sequestering it maybe for a few years; meat cows live about two years.
> “Kangaroos have a very different stomach from that of ruminants such as sheep and cows,” Professor Clauss said. “We think that the methane is low because of the way food moves through the kangaroo stomach, and not because of a unique gut fauna.”
> Dr Munn and Professor Clauss are critical of efforts to try to reduce greenhouse gas emissions from ruminant livestock by replacing their gut fauna with that from kangaroos or other low-methane emitting animals, which they believe is unlikely to succeed.
You're not raising kangaroos in Scotland, right?
So yes, you're correct - I'm not raising roos in Scotland, but we do look into ruminants, biomes, etc here.
These are complex chains that make up the surface level carbon cycle. Not every path leads to carbon dioxide / methane production, the gas creation ratios can be tweaked by the paths taken.
The problematic carbons are those that are additional - those once buried across the course of millions of years, some millions of years ago and now being bought to the surface in an extremely short timescale (one century and half, roughly)
This all goes to your question if you care to look into it.
In Scotland?

Meat production accounts for somewhere between 15 and 20% of human emissions. It is a significant part of the problem.

To a point. Producing and consuming meat is gonna emit carbon. This isn’t disputable.
