Search engines and web pages CO2 impact

The forecasts for the future are not positive: according to the Iet, Institution of engineering and technology, consumption is expected to double between now and 2025. On the one hand there is the consumption generated by the manufacture of devices such as smartphones, computers and the servers themselves, and on the other the energy they consume. According to, it is the use of the search function that wastes the most energy, as it runs more than one server. Web search, for example, emits 1.7 grams of CO2 per page consulted, while a website with 10,000 page views per month emits 211 kg of CO2 per year. However, according to Google figures reported by the BBC, an average user of its services (who performs 25 searches every day, watches 60 minutes of YouTube and has a Gmail account) produces less than 8g of CO2e per day. This is because Google now uses a mixture of renewable energy and carbon offsetting to reduce its carbon footprint, while Microsoft, which owns the Bing search engine, has promised to become carbon negative by 2030.
