People often underestimate the impact of social media scrolling on their carbon footprint because other things tend to get more attention. But how much does it affect our personal emissions? According to the study, the most polluting app is TikTok, which, despite having only a third of Facebook's user base, produces more CO2 than any other competitor. They have a solid 30% lead over rival Reddit in per capita emissions with 30.72 kg of CO2 per user per year. For comparison, this equates to 0.38 % of the average carbon emissions of a Chinese citizen in 2021, which is slightly more than a flight from Beijing to Tianjin. If you scrolled through TikTok every day for as long as the average user does (32 minutes a day) for your entire life, you would generate slightly more carbon emissions than flying from Beijing to Malta.
