If you are concerned about your carbon footprint, this extension is for you. Cloud Carbon calculates how much energy you have spent browsing Facebook, Netflix, and Youtube.

All you have to do is install this on your Chrome browser. Every time you open a new tab, it will display a breakdown of how many gallons of gas you could have used browsing these websites. It also shows the total number of gallons.

This helps users see how much carbon footprint they contribute when browsing some sites and see its impact to the world.
