How much CO2 does a search on ChatGPT emit?

About this episode

AI is everywhere—from helping us write emails to planning our meals. But while it may feel invisible, it comes with a real environmental cost. According to a 2024 Ifop-Talan survey, 70% of young adults use AI every day—without realizing how much energy and water it consumes. A 2024 study by researcher Shaolei Ren found that generating a short 100-word email with AI uses the same amount of energy as keeping 14 LED bulbs on for an hour—and nearly a bottle of water. Multiply that across millions of users, and the environmental footprint becomes significant. A single ChatGPT request emits between 2.5 and 5 grams of CO₂, and just 10 daily exchanges over a year could add up to nearly one ton. Why does AI consume so much energy? What are tech companies doing to reduce its environmental impact? And can AI ever be truly sustainable? In under 3 minutes, we answer your questions!
