This carbon calculator, developed by the EPA, guides students in calculating their carbon footprint and then using that information to make decisions about how to reduce their carbon emissions.
The CLEAN collection is hand-picked and rigorously reviewed for scientific accuracy and classroom effectiveness. Read what our review team had to say about this resource below or learn more about how CLEAN reviews teaching materials
The interface is easy to use.
Finding "sources and assumption" tabs at bottom of spreadsheet is somewhat difficult.
This is a self-directed website designed primarily for middle and high school students in both formal and informal educational contexts, including classrooms camps and after-school programs.
A nice resource from the EPA that complements the "Calculate your carbon footprint" calculator. This one converts current activities (and those the user will change) to pounds of carbon saved and finally miles driven by cars. A quick exercise involving 16 activities like "Turn off the water when you brush your teeth, "Bike or walk to school instead of getting a ride", "Recycle newspaper", "Unplug chargers when they are not in use", "Enable the sleep feature on your computer", etc., gives savings for each activity as well as personal totals. Reduction of carbon emissions is translated into a carbon equivalency of miles driven in a car. Additionally, information on the basis of the calculations is given in "sources and assumption" tab on the downloadable spreadsheet.
Comments from expert scientist: The Carbon Calculator is a straightforward exercise that gives the user a clear understanding of the impact of individual and collective carbon choices. Assumptions behind each calculation are not specifically stated.
There is a link to many examples of how this EPA Global Climate Change website, including the carbon calculator, can be used. The link can be accessed at the horizontal menu at the very bottom of the screen under Educator Resources.
A possible follow up activity is to have students convert English units into metric units.
