3. Content
• What is a ‘Carbon Footprint’?
• How do you measure your carbon footprint?
• How is carbon footprint useful?
6. What does the ‘Carbon’ mean?
O2
H2O
Other gases and fumes
The ‘carbon’ mentioned in carbon footprints usually
means the carbon that occurs from burning fossil fuels
9. What is a ‘Carbon Footprint’?
If the world was a beach and our
activities are our walking,
• Bigger feet, bigger footprints
• More walking, more footprints
Focus on human activities only
So, the carbon footprint is like a
trail of footprints leftover from
our activities
10. The Greenhouse Effect
Do you know
that water vapor
is also a GHG?

11. It’s not just CO2, it’s Greenhouse Gases
CO2 1 x 100 = 100
CH4 21 x 100 = 2,100
N2O 310 x 100 = 31,000 +
HFCs 140 x … = …

12. How do you measure tonnes of GHG?
24/7 or Take Samples
tonnes
+
of GHG
Measure the source of GHG
C + 2x O CO2
12 g/mol 16 g/mol 44 g/mol
Use scientific estimates per level of activity
Activity Data x Emission Factor = GHG Emissions
Liters of Gasoline kgCO2 per liter of Gasoline
Tonnes of Cement Production tCO2 per tonne of Cement Production
km of road driven kgCO2 per km using small car
… …
13. Source: IPCC 2006 Guidelines: Energy Volume
67,500 kgCO2per TJ (1012 J)
3 kgCH4 per TJ (1012 J)
0.6 kgN2O per TJ (1012 J)
14. Source: API Compendium 2009
GWP
x 67,500 kgCO2per TJ (1012 J) = 2.234 kgCO2/Liter x1
33.1 MJ/Liter x 3 kgCH4 per TJ (1012 J) = 0.0000993 kgCH4/Liter x 21 = 2.242 kgCO2e/Liter
x 0.6 kgN2O per TJ (1012 J) = 0.0000198 kgCO2/Liter x 310

Tank Size: 17.0 Gallons or 64 Liters
64 Liters x 2.242 kgCO2e/Liter = 143.5 kgCO2e per tank
16. Emission Factors – Tier Levels
A tier represents a level of methodological complexity
• Tier 1 – basic method
• Use readily available national or international
statistics, default emission factors and other additional
parameters
• Tier 2 – intermediate method
• Use technology specific statistics
• Tier 3 – most demanding in terms of complexity and
data requirements
• Use site specific statistics
2006 IPCC Guidelines for National Greenhouse Gas Inventories
17. Sources of GHG Emissions
1. Fuel Combustion Emissions – emissions resulted from
burning fuel
• Stationary Fuel Combustion
• Boilers, generators, etc.
• Mobile Fuel Combustion
• Trains, planes, automobiles, ships, etc.
2. Process Emissions – emissions resulted from chemical
reactions
• Plastic production, cement production, etc.
3. Fugitive Emissions – leakage of substances that are on-
their-own GHGs
• Natural gas leaks, refrigerant leaks, landfill gases, livestock, etc.
18. National GHG Inventory
• According to the 2006 IPCC Guidelines for National
Greenhouse Gas Inventories, the reporting of GHGs are
separated into 4 categories
1. Energy
• Fuel use, petroleum production, energy
production, transportation, etc.
2. IPPU – Industrial Processes and Product Use
• Chemical reactions, uses of GHG-contained products and
chemicals, etc.
3. AFOLU – Agriculture, Forestry and Other Land Use
• Livestock, farming, land utilization, etc.
4. Waste
• Domestic waste, landfills, water treatment, waste
management, etc.
19. Yeah, we contribute to global
warming, too, you know?

22. How is Carbon Footprint useful?
• Not until we know how much we emit can we determine how
to reduce our emissions
• Several global organizations are finding ways to reduce our
emissions
• Penalty schemes
• Kyoto Protocol Annex I countries
• Airline carbon fees
• Incentive schemes
• CDM Projects
• Carbon credit exchange markets
23. Future Topics
• GHG Accounting and Reporting System
• CDM Projects and Carbon Credit
Exchange Markets
• Green Buildings
• Green Business Opportunities and Green
Entrepreneurs
• Much, much more…
Scope 1: emissions are those over which a company has direct control via ownership of activities;Scope 2: is purchased electricity, heat or steam; andScope 3: all indirect emissions that occur as a result of facility or business activities that use goods or resources with potential greenhouse gas emissions
