> In fact, I'd love to see a back-of-the-envelope calculation of how many tons of CO2 would have been saved in total if HTML was a well-engineered binary format.

Things like React (server-side and client-side: think of all those poor <div>s!) waste far more resources than decompressing and parsing HTML.
