If you want to talk about climate change then electronics is the wrong place to point the finger at. For start look at cement manufacturing. It requires huge amounts of energy to produce even though we have eco-friendly variants ready to go. And cement production amounts to 8% of all greenhouse gasses released annually.

Hell, just ban private jets and you've offset all of the bad things datacenters ever made. Elon had 10 minute flight to avoid traffic which consumed around 300l of fuel. Royal family makes so many flights a year that you could go into the wild and eat bark until the rest of your life and you wouldn't be able to offset their footprint in thousands of lives.

Bill Gates himself talks a lot about reducing carbon footprint we make and yet he refuses to sell his collection of airplanes. He has A COLLECTION of them.

Using higher level language that requires more operations than assembler is not a thing to worry about when talking about climate change. Especially without taking into account how much pollution have those managed to reduce by smartly controlling irrigation and other processes.
