Carbon footprinting for HULT
- 1. Intro to Carbon Footprinting Piyapong Muenprasertdee
- 2. Work Experience • Environmental Resources Management, Thailand Office • Sustainability and Climate Change Concentration Team • Assistant Consultant (2008-2011) • Key Projects • GHG Accounting and Reporting Standard • For large Oil and Gas company • Carbon Footprint • PET Resin and Bottle production • CDM Projects • Hydropower project • Heat recovery generator in cement production • National GHG Inventory • Hong Kong SAR • LEED Green Building • An international bank’s new head office in Bangkok
- 3. Content • What is a ‘Carbon Footprint’? • How do you measure your carbon footprint? • How is carbon footprint useful?
- 5. What is a ‘Carbon Footprint’?
- 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
- 7. Carbon Neutral CO2 CO2 Time
- 8. Fossil fuels introduces new CO2 (actually ancient CO2 back) into the atmosphere CO2 CO2 Time
- 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? http://greenhouse-guides.blogspot.com/2011/06/greenhouse-effect-does.html
- 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 … = … …… …… PFCs to SUM of tCO2e SF6 23,900 Kyoto Protocol GHGs (through 2012)
- 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
- 15. Toyota Camry 3.5L 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? fart... CH4 fart... CH4 CH4 FaRR...T… CH4 FAAA…..AAART!!!
- 20. World GHG Emissions by Sector and Gas (2005) http://www.wri.org/image/view/11147/_original
- 21. Corporate GHG Accounting & Reporting http://www.crchallenge.org/about/faqs/
- 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…
- 24. THANK YOU
Editor's Notes
- 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
