The Internet is globally causing more Co2 emissions than many countries. While a single page view only leads to single grams of Co2 emission, when you add up thousands of visitors, the average website can emit as much as 96 kilograms of Co2 per year. For comparison, emissions per passenger on an typical flight is less than 90 grams per kilometer traveled. For a business or organization, which typically has higher than average levels of website traffic, that number can be many times higher.
