Some possibilities: AI aided material design could help create more efficient solar cells or batteries. Google issue a report how AI aided shipping logistics planning could optimize many aspects of the process. Project Starline (AI enhanced video conferencing) could reduce the need for business travel. Broadly, anything being done to improve energy efficiency certainly uses computers in design or planning. Anything using computers stands to be made more efficient with AI.

Google has been using ML for years to optimize cooling in data centers.

(I agree with gp though)

If Google starts using AI to calculate their emissions, they can report incorrect numbers that look better.

Ai can eliminate some office jobs. No jobs -> no office -> no commute -> less emissions.

I assume they will ask the AI on how to reduce emissions.
