Technology's impact on climate change
summary
Tech produces about 830 million tonnes CO2 (≈2% of global emissions) and the internet may use up to 20% of electricity by 2030; data centers now use ~3% of global electricity and produce ~2% of greenhouse gases. Concrete measures include running a Lighthouse audit, testing sites with the carbon website calculator and Chris Adams’s equivalencies, trimming unused JS/CSS, lazy-loading and optimizing images, avoiding autoplay videos and heavy embeds, choosing hosts from the Green Web Foundation, and preferring downloads over streaming to cut surprising per-page and per-stream emissions.
