Carbon Footprint Created by: Mrs. Dube

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?

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?

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

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

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?
