Have you ever wondered what your role is in helping and hurting the environment? Use the website below from the U.S. Department of Energy and your knowledge of calculating the median of a large set of data to calculate your city’s median carbon footprint! A carbon footprint is the total amount of greenhouse gas (GHG) emissions created by a person, household, or organization. Every time we burn fossil fuels to power our homes, cars or to make the items we consume, carbon dioxide is emitted up into the atmosphere. Use this website and the map of the carbon emissions in your area.

Enter your zip code (or the zip code of a city in U.S. city that you have heard of, if you don’t live in the U.S.) in the website above. Then click on the pins to get information about the Annual CO2\begin{align*}CO_2\end{align*} emission for your area. As you click on the pins, use your graphing calculator to put the data into a list. Follow the directions from the previous lesson to calculate the median carbon footprint for your city!

1. What is the median carbon footprint of your city?

### Extension Investigation

2. What is the mean carbon footprint of your city?
3. What is the mode carbon footprint of your city?

4. Now that you have calculated your city’s median carbon footprint, what are some ways that you could lessen your carbon footprint? Brainstorm at least eight ways! Then make an action plan for how you and your family can lessen your environmental impact. Then share it with your family!
