To measure the carbon emissions of websites, please follow the instructions below to get an estimated .

> Find one or two websites you’d like to carbon-measure using websitecarbon.com

> Enter the results of the measurements in the highlighted area below

> Compare the emission rates you found with other data entries on the sheets. If you like, share and discuss findings with a person next to you.

> (Optional) Research the number of visitors on your investigated page per year (or a different designated period), and multiply the measured emission amount of the page by the visitor number - to estimate (roughly) the carbon emissions of the page for the period of access. Then, enter the results on the spreadsheets.
