Much discussion around your website's environmental impact hinges on page weight and performance.

This is very important, and please try and make your website small and fast.

I haven't seen many people talking about how `rel` attributes could benefit the environment, and I think they do!

Anything you post online will be visited by lots of bots and spiders, which burn energy.

If you're linking to a page that doesn't benefit from being crawled `rel="nofollow"` to save effort.
