Thanks, that’s interesting. IEA definitely seems like a solid source for this kind of thing.

1% (if that’s accurate) isn’t nothing, but it’s also nowhere near what seems to be implied by the level of people’s reaction to AI buildout and the framing as an environmental catastrophe. (Of course there are other factors, such as local pollution from gas turbines.)

Interesting comparisons are blast furnaces (6% of global emissions) and aviation (2.5%). Both arguably more economically necessary than AI, for sure, but if we could make either of those meaningfully less of a contributor to climate change we’d have covered the whole AI buildout. And that’s not even getting into the possibility of a transition to solar energy for running datacenters, which China is already deep into and in which the US is far behind.
