The "mitigation" in question is buying carbon offsets (I mean there are improvements in DC efficiency also, but those only do so much, and language models ballooning 100x isn't going to be fixed with 10 or 50% efficiency improvements). For the moment "carbon neutrality" is only achieved through the purchase of energy offsets.
That doesn't mitigate. It offsets. Don't get me wrong, still better than nothing, but its not a mitigation.
If you're going to bring carbon emissions into it, mentioning current mitigations as well seems relevant unless you're writing an op/ed piece.
