Description:
Using GreenLearning’s GHG calculator, students identify and commit to personal actions to reduce their GHG emissions. During the course of teaching this unit, students can check in on their actions. As part of the Culminating Activity, students calculate the actual reduction in GHG emissions that resulted from their individual and collective actions and reflect on this.

Student Prompt:
Introduction
Watch the video on how human activities contribute to global warming.
Basic Knowledge
Answer the following two basic knowledge questions:
1. What are the greenhouse gases (GHG)?
2. Explain how these gases warm the earth.
Taking Action to Reduce Your GHG Emissions
On your own or in a small group, brainstorm a list of activities in your life that contribute to GHG production.
Which of these activities could you change to reduce your GHG emissions?
Open the GHG Calculator spreadsheet on your computer.
Are the list of actions in column A similar to your list of actions that you could take to reduce your GHG emissions.
In order to calculate exactly how much GHG you could save you must quantify your action. For example, the action of “turn off TV” is too vague. You must specify how many hours the TV will be off when previously it had been on. Your action might be to reduce TV time by 1 hour per day. If you enter 1 in cell B25, you will find that this action reduces your GHG emissions by 24.04 kg per year (see cell E25).
Open the sample GHG Calculator spreadsheet.
What actions are being pledge by this individual?
Which action is most effect in reducing GHG emissions?
How much is the individual’s annual reduction?
Complete the GHG Calculator spreadsheet for your own actions. Submit it to your teacher.
