Reddit carbon footprint

This may not be the place to ask but can anyone explain to me why on a per minute basis Reddit has the second highest (after TikTok) carbon emissions of all the major social media platforms. I get why overall it is higher due to the number of users. I get why TikTok is high on a per minute basis. It uses lots of video and other media but Reddit is just basically the written word. I came to Reddit thinking because of that that it would have a lower impact but apparently not. Any explanation anyone?
