When it comes to web design, the best thing you can do for the environment is nothing. Decide not to have a website or app or chatbot. Decide not to publish that new content. Even better, decide to remove an old website, to delete lots of useless web pages.
There’s about 1.8 billion websites out there. One website for every four people on the planet. Ninety-one percent of web content never gets found in Google. Digital has opened the floodgates of crap. Enormous, unbelievable quantities of crap. Data centers are really very expensive and very polluting data dumps.
