I always see posts about how streaming emits CO2 and has a high carbon footprint but I don’t actually understand how that happens.

Let’s say you want watch your favorite movie 10 times.
If you are watching on DVD, you just play it 10 times.
If you stream it 10 times, you need to completely download the entire movie 10 times.
The physical DVD needs to be pressed, packaged, sold, and delivered. All of those steps take energy, but only happen once. After that you only need to power the DVD player (and screen) for each play.
Streaming means several servers need to be running all day, every day, ready to send the entire movie file to as many people as want to watch it. Delivering over the internet requires several servers and additional equipment to use power each and every time it gets streamed. You still need to power the screen (and stream player) for each play too.
