Python is an ecological disaster. It's a strong argument against it. If people are truly concerned then they should switch.
Evidently, you will be able to link a study that, instead of merely CPU and RAM at runtime, accounts for the energy consumption of the human developers during the vastly different amounts of development time required to produce code of equivalent or nearly equivalent functionality in those various languages. Otherwise, you would be selecting a narrow slice of the energy cost to suit your conclusion, and using this to claim anything about the environmental impact would be both unscientific and ridiculous to such a degree that Greta's happiness would be much better served by simply handing her Hermione Granger as a girlfriend.
