Automatically estimates the CO2 emissions for driving on routes suggested by Google Maps.
Whenever you ask Google Maps for driving directions, this browser extension automatically estimates the total CO2 emission for the driving route suggested by Google Maps. The estimation is then shown to the left of the map, next to the route's total distance.
To see how many trees you need to plant and how long you need to wait for them to offset the displayed CO2 emission, just hover the mouse over it for a few seconds.
In order to improve the accuracy of the estimations, remember to set up the rate of emissions of your car by clicking on the "earth icon" that appears in the address bar when this extension is activated (i.e. when you ask for directions in Google Maps).
If you find any issues, please report them to MapsCarbonFootprint@gmail.com, and they will be fixed as soon as possible.

Features planned to be released in new versions:
1) Right now, estimations always assume that you are using a car, even if you ask for public transportation, biking or walking directions. Estimations for these other kinds of routes will be implemented in the next version. If you know where I can find reliable emission rate estimations for public transportation, please let me know.
