summary
Claims that digital causes 3–4% of global GHGs and that 60% of emissions happen at the device level drive this talk, with data about short device lifespans (60% replaced within two years) and a concrete optimization: converting PNG to WebP cuts image size ~90% and reduces a 64‑speaker page to ~10.3 kg CO2 for 10k views on a German grid. Practical tactics listed: lazy loading and offline‑first, limit analytics, use Glide/Coil, and measure download and update size plus install and runtime storage to guide real changes.
