Narrator: This is Science Today. Most people have heard that unplugging appliances or reusing grocery bags are enough to reduce their carbon footprint, but researchers at the University of California, Berkeley now say that, depending on who you are, those small habits may not be the best way to reduce your emissions. New research reveals that carbon footprints are more unique than previously thought.
Jones: What we found is that carbon footprints vary quite significantly from one location to the next. So if you live in an area where your electricity is produced with coal, household energy is going to be a much bigger portion of your carbon footprint.
Narrator: Researcher Chris Jones developed an online carbon calculator that enables households to track their unique carbon footprint and develop a personalized plan for reducing their emissions.
Jones: We try to make it quick and easy. Where you live, how many people are in your household and your income will give you a pretty good idea of what opportunities exist for your particular household.
