How does Canada's CO2 emissions compare to other G7 countries?
Carbon dioxide (CO2) is a greenhouse gas. This means it's a "gas in the Earth's atmosphere that traps heat.” Think about greenhouse gases as tents. If you're camping, the tent covers you and keeps in warm air.
So where does CO2 come from? Commonly, it comes from burning fossil fuels (fuels made from decomposed organisms) such as coal or oil. For example, when you drive a car with a combustion engine, it burns gasoline. When the gasoline is burned, it releases CO2.
We used data science to learn how Canada's CO2 emissions compared to other G7 countries. The G7 is a group of seven nations that meet to discuss international and local issues.
To answer our question, we:
- Gathered data from World Bank Open Data about CO2 emissions in G7 nations. “Per capita” means emissions for each person in each nation.
- Created a line graph to compare each nation's CO2 emissions. We call this line graph a data visualization.
Reflect on what you see
Look and interact with the data visualization above. When you mouse-over the line graph, you’ll notice more information appears.
Think about the following questions:
- What do you notice about the line graph?
- What do you wonder about the data?
Use the fill-in-the-blank prompts to summarize your thoughts:
- “I used to think_______”
- “Now I think_______”
- “I wish I knew more about_______”
- “This data visualization reminds me of_______”
Share your reflections
Below are some ways to share your thoughts about the data visualization. If you want to publish your reflections online, make sure you check in with your teacher or guardian.
- Blogging (there are many free blogging tools)
- Creating videos (here’s a guide on creating YouTube videos)
- Drawings (Google Drawings is one tool you could explore)
