First of all, that 'carbon calculator' website is total bunk. How the hell do you tell how much work needs to be done in the back-end to display your page?

How does it tell apart if a site lazy-loads, meaning it might do less work on first load, but does way more total traffic to render all the information the user requests?

I'd wager the majority of energy is spent in the backend, where the majority of the energy will be spent between microservices ping-ponging each other.
