Transcript of "Ecocem green economyexpopresentation 20may-ver2a"

  1. 1. The significance of Embodied CO2<br />Ecocem Ireland Ltd<br />
  2. 2. CO2 in construction<br />Embodied CO2 emissions = arising from creating maintaining and demolishing the asset<br />Operational CO2 emissions = arising from using the asset<br />Operational CO2<br />Total CO2<br />+<br />=<br />Embodied CO2<br />Ref: S. Sturgis & G. Roberts, “Redefining Zero: carbon profiling as a solution to whole life carbon emission measurement in buildings”, May 2010, RICS Research<br />
  3. 3. SEAI Mission<br />“To play a leading role in transforming Ireland into a society based on sustainable energy structures, technologies and practice”<br />The SEAI strategy to date is focused on operational CO2<br />SEAI Strategy<br />Ref: SEAI - 2010-2015 strategic plan<br />
  4. 4. SEAI Strategy<br />SEAI strategy is subdivided in 5, 15 & 25 year horizons<br />Building materials are only referenced in the 25 year strategy:<br /><ul><li>“All buildings at least energy self-sufficient. Building materials [to] have minimal environmental impact”</li></ul>This should be part of the current 5 year strategy<br />Ref: SEAI - 2010-2015 strategic plan<br />
  5. 5. Embodied CO2<br />Embodied CO2 of the built environment is 11% of global annual emissions (approximately 3 billion tonnes).<br />The embodied CO2 used to create a building may be as high as 62% of its total whole life emissions.*<br />Success in reducing operating CO2 has raised embodied CO2, relatively and absolutely. <br />A reduction in Embodied CO2 has an immediate benefit in tackling Climate Change.<br />Ref: S. Sturgis & G. Roberts, “Redefining Zero: carbon profiling as a solution to whole life carbon emission measurement in buildings”, May 2010, RICS Research<br />
  6. 6. Impact of building regulations on operational/embodied CO2<br />Ref: SEAI “ A Guide to Building Energy Rating (BER)”<br />Ref: PM Group: “Embodied CO2 of housing construction in Ireland” - Architecture Ireland – Jan/Feb 2010<br />
  7. 7. CO2 in construction<br />Typical different whole life carbon splits for different types of buildings<br />Embodied CO2<br />Operational CO2<br />Ref: S. Sturgis & G. Roberts, “Redefining Zero: carbon profiling as a solution to whole life carbon emission measurement in buildings”, May 2010, RICS Research<br />
  8. 8. CO2 in construction<br />Typical different whole life carbon splits for different types of buildings – in 10 years time <br />Embodied CO2<br />Operational CO2<br />Ref: S. Sturgis & G. Roberts, “Redefining Zero: carbon profiling as a solution to whole life carbon emission measurement in buildings”, May 2010, RICS Research<br />
  9. 9. Case Study: 3-bed semi detached house<br />
  10. 10. Embodied CO2<br />Concrete accounts for 55% of embodied CO2 of a typical 3 bed semi-detached house<br />ref: PM Group: Embodied CO2 of housing construction in Ireland Architecture Ireland – Jan/Feb 2010<br />
  11. 11. Reduction in Embodied CO2 through the use of GGBS<br />Original Embodied CO2<br />(38.7 tonnes)<br />Reduced Embodied CO2<br />(25.8 tonnes)<br />ref: PM Group: “Embodied CO2 of housing construction in Ireland” - Architecture Ireland – Jan/Feb 2010<br />
  12. 12. Two simple points<br />In construction, concrete is the main contributor to embodied CO2<br />Cement + GGBS is the best available technology to reduce embodied CO2 in construction.<br />
  13. 13. What is GGBS cement<br />Ground Granulated Blastfurnace Slag<br />
  14. 14. GGBS Manufacture<br />Steel Manufacture<br />Water to make GBS<br />GBS<br />Grind to make GGBS<br />Store GGBS for distribution<br />
  15. 15. GGBS and the Environment<br />CO2 emissions for cement and GGBS production<br />Typical CO2 Emissions for Portland Cement and GGBS Production (Figures in kg per tonne of output)<br />Ref: British Cement Association – Fact Sheet 18 [1]<br />
  16. 16. GGBS and the Environment<br />Typical Energy usage for Portland Cement and GGBS Production<br />Ref: E. Kennedy, The Integration of the Measurement of Energy Usage into Road Design, National Roads Authority, Dublin. 2006<br />
  17. 17. GGBS and the Environment<br />Energy Usage in Barrels of Oil for Portland Cement and GGBS production<br />
  18. 18. Industry sector 2030 cost curve<br />≈ 300,000 tonnes<br />Ref: SEAI - “Ireland’s Low Carbon Opportunity” – July 2009 <br />
  19. 19. Industry sector 2030 cost curve <br />Further opportunity to increase CO2 abatement at negative cost<br />≈ 600,000 tonnes<br />Increases abatement <br />potential up to 2.3m tonnes<br />15% increase <br />Ref: SEAI - “Ireland’s Low Carbon Opportunity” – July 2009 – amended by Ecocem<br />
  20. 20. Financial effects<br />Value of €35/tonne CO2 derived from EU Directive 2009/33/EC Promotion of Clean Energy Efficient Road Transport Vehicles and UK Government Climate Change Act 2008 – Shadow Price of Carbon<br />OECD “Ancillary benefits and costs of GHG mitigation: Policy Conclusions” ENV/EPOC/GSP(2001)13/FINAL, April 2002<br />Based on a price of $80/barrel<br />Based on quarrying cost of €10/tonne.<br />Financial effects of 600,000 tonne CO2 abatement<br />
