7 Name:... Carbon comparisons During the investigation your class has worked out a number for the total amount of carbon stored by the trees on your school site in kilograms of carbon, but what does that mean? Let s find out! How do we release carbon into the atmosphere? Burning fossil fuels Our use of fossil fuels including coal, oil and gas to generate power is one of the ways that humans release CO 2 into the atmosphere. As the fuels are used to generate electricity in the power stations, CO 2 is produced and escapes into the atmosphere. We use the electricity to power many of the machines, gadgets and devices that we take for granted and use every day. We can estimate the amount of CO 2 released when we use different devices for hours, days, weeks or months. This is called the carbon footprint of the device. Usually a carbon footprint is measured as carbon dioxide (CO 2 ) rather than carbon (C). Luckily it s really easy to convert between C and CO 2, we just need to multiply our total carbon value figure by 4. Fill out equation below: Total carbon value (kg C) x 4 = (kg CO 2 ) Student Resource Investigation 4 - Trees STUDENT RESOURCE 6

8 How much CO 2? The table below shows how much CO 2 is emitted to power these everyday gadgets. How much of this CO 2 could have been absorbed by the trees in your school? How long could you use each gadget for? Kilograms of CO used Kilograms of CO used Hour Day Week Month Year Hour Day Week Month Year Student Resource Investigation 4 - Trees STUDENT RESOURCE 7
