The Internet is responsible for more CO2 emissions globally than many individual countries. While a single page view typically produces only a few grams of CO2, multiplying that by all your visitors over a year can result in your website emitting several metric tonnes of CO2. For comparison, emissions per passenger on a typical flight are less than 90 grams per kilometer traveled. For businesses or organizations, which usually have higher-than-average website traffic, this number can be significantly higher.
