I used to plan data centers for booking.com and some special expert from Gartner or something asked how much CO2 we would save if booking was written in Golang instead of perl.
Booking filled the equivalent of 40 jumbo jets per day with flights at that time.
The combined daily data center energy use was a few hours of flight of one engine of one jet per day.
I told them to go and stop flights to have an impact, they didn't.

Hacking won't help the climate.
Politics can.
Tax billionaires. Ban Bitcoin. Prohibit GenAi. Limit data centers. Tax flight fuel fairly. Ban cars and build public transport. Stop using concrete. Demand heat pumps.
That works.
