Worksheet 1.2 Greenhouse gas emissions

Answer the following questions after reading section 1.2: Greenhouse gas emissions (pages 19-30).

When possible, use your own words.

Greenhouse gas emissions, 1990-2005

1. What are the six categories of greenhouse gas emissions as classified by Canada's 2007 National Inventory Report?
   
   
   
   
   
   
   
   
   
   
   
   
2. In 2005, what amount of CO₂ equivalent of greenhouse gases did Canadians emit to the atmosphere?
   
   
   
   
   
   
   
   
   
   
3. Based on Table 1.3 and Chart 1.3, how much greenhouse gas did Canadians emit to the atmosphere in 1990? In 1995? In 2000? What trend do these data reveal?
   
   
   
   
   
   
   
   
   
   
   
   
4. What is Canada's Kyoto target? Are we approaching it?
   
   
   
   
   
   
   
   
   
   
   
   
5. Using the classifications in question one, what is the largest source of greenhouse gas emissions in Canada, accounting for more than 80% of total emissions in 2005?
   
   
   
   
   
   
   
   
   
   
   
6. Table 1.3 illustrates the breakdown of Canada's sources of greenhouse gas emissions. Create a circle graph/pie chart of the greenhouse gas emissions by source in 2005, using the categories from question 1 and omitting Land use, land use change and forestry.
   
   
   
   
7. Transportation is a major source of greenhouse gases. The section entitled "Contributions from energy production and consumption" includes the following text:

   "Transportation activity is a major source of emissions related to the combustion of fossil fuels, and accounted for 33% of emissions and 37% of growth in energy-related emission sources since 1990. Of particular note was the 109% increase in the emissions from light-duty gasoline trucks (from 21.3 Mt in 1990 to 44.5 Mt in 2005), reflecting the growing popularity of sport-utility vehicles, vans and light trucks."

   Look at Table 1.3 and show how the calculations were done to arrive at the percentage change values above.
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
8. Table 1.3 illustrates a negative value for the final category: land use, land – use change and forestry. Explain what this negative value means (Tip: see the section 'Non-energy emissions').
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   Putting greenhouse gas emissions into context
   
9. List possible reasons why Canada ranked first in growth of greenhouse gas emissions from 1990-2004 of all the G8 countries, and explain why these factors are related to increased emissions.
