2. What is a Carbon Footprint?
A measure of the greenhouse gases that individuals or groups emit into the atmosphere
Carbon footprint is measured in tons of carbon dioxide emitted
What is a Carbon Footprint?

3. What are Greenhouse Gases?
There are six main greenhouse gases:
Carbon dioxide, also known by its chemical formula CO2
Methane, also known by its chemical formula CH4
Nitrous oxide, also known by its chemical formula N2 O
Troposheric Ozone, its chemical formula is O3
CFC-12 whose chemical formula is CCL2F2
HCFC -22 with CCl2F2 as its chemical formula
What are Greenhouse Gases?

4. Source of Greenhouse Gases
Carbon dioxide (CO2 ) – found in fossil-fuel combustion, land-use conversion, cement production
Methane – found in fossil fuels, rice paddies, waste dumps
Nitrous oxide – found in fertilizer, industrial processes, and combustion
Source of Greenhouse Gases

5. Sources of Greenhouse Gases
CFC- 12 – found in liquid coolants and foams
HCFC -22 – found in refrigerants
Tropospheric ozone – found in fossil fuel combustion, industrial emissions, and chemical solvents
Sources of Greenhouse Gases

6. Fossil fuels - are hydrocarbons (chemicals made up of carbon and hydrogen) such as coal, oil and natural gas, that come from the organic remains of prehistoric organisms
Energy released can be harnessed to produce electricity, power vehicles, heat homes, cook food and much more.
Also used in the production of important materials such as plastics
What are Fossil Fuels?

7. Why Do We Care About Carbon Footprint?

10. Climate change – refers to the variation in the earth’s temperature
Rise in the average surface temperature
Caused by increased levels of carbon dioxide
