Right. Faster generally means less CPU used for a particular use. For example I made ls(1) a bit faster recently.
Even though not really noticeable per run, given how often it is run I estimated this to save 9 tonnes of carbon emissions per year.

Is the posted link supposed to be a reference? That is your own tweet aka self-reference, boasting your own contribution.
In the tweet itself you say "estimate"! How do arrive at such a grandiose estimate?
How do you attribute a saved carbon footprint to an optimization in a command line tool? You cannot even approximate that. I would argue that such tiny optimizations make 0, nil difference in overall energy consumption on my local machine, all my laptops and all the servers in this building.
I'm not saying that we shouldn't run optimized code, but everyone can scream around random numbers.
