How much CO2 is your website responsible for?
Do you manage a website or a blog? If so, do you have any idea how much CO2 goes into keeping that website online? How much energy do your hosts' servers use? How much electricity is used by all the people viewing it?
The answer for most websites will be 'not much'. However considering the size of the web these days, collectively all these small sites are having a big impact.
To help you find out how much CO2 your site is responsible for you can embed a widget from CO2 Stats. Designed by academics from MIT and Yale, this widget automatically calculates the greenhouse gas footprint of visits to your site, based on locations of your visitors and servers, computer types, window and monitor sizes, local fuel mixes, download sizes and times.
For sites with less than 100 impressions a month CO2 Stats will automatically offset the emissions for free. There are then a series of packages for larger sites to offset their emissions.
This is a web app to watch out for as it doesn't have any competition at the moment so it could become very big very quickly.
