1 Byggmaterialdagen Stockholm 3 April 2008 Björn Stigson, President of WBCSD Minskad miljöbelastning i framtidens byggande

2 WBCSD: An overview  Coalition of 200+ companies represented by CEOs  Stock market value: 8,000 BUSD  Supplies products and services to half of the world’s population every day  Regional Network with local organizations in 60 countries 2 Byggmaterialdagen, Stockholm 3 April 2008

3 3 Oil Biomass Gas Coal Nuclear Renewables Primary Energy Liquids Direct combustion Industry and Manufacturing Mobility Final Energy Consumer Choices Energy Buildings Power Generation Access to energy is key for society

4 CO 2 Emissions - 450 Stabilisation Case Achievable or Science Fiction? By 2030, emissions are reduced to some 23 Gt, a reduction of 19 Gt compared with the Reference Scenario 10 15 20 25 30 35 40 45 200520102015202020252030 Gt of CO 2 CCS in industry – 3% CCS in power generation - 9% Nuclear – 13% Renewables – 20% Switching from coal to gas - 8% End Use electricity efficiency -17% End Use fuel efficiency – 30% Reference Scenario 450 Stabilisation Case 27 Gt 42 Gt 23 Gt Energy-Related CO 2 Emissions (IEA) 4 Byggmaterialdagen, Stockholm 3 April 2008

5 Going Forward What does a society look like that emits 60-80% less GHG emissions by 2050? –“Different” –Major impacts on lifestyle, consumption patterns and infrastructures are likely –New public-private partnerships will be needed Energy and Climate  a societal transformation challenge 5 Byggmaterialdagen, Stockholm 3 April 2008

6 Urgent Challenge The Urgent Challenge of Energy Efficiency –Buildings today represent about 40% of world’s energy demand: 33% in commercial buildings 67% in residential –Worldwide energy consumption for buildings is expected to grow up to 45% from 2002 to 2025. 6 Byggmaterialdagen, Stockholm 3 April 2008

7  Demographics  Living standards  Lifestyle changes  Design, technology and new equipment  Climate change Drivers for site energy demand 7 Byggmaterialdagen, Stockholm 3 April 2008

8 What if? 8 Byggmaterialdagen, Stockholm 3 April 2008 * Refers to residential and commercial (excludes industrial sites) *

9 A world where buildings consume zero net energy A world where buildings consume zero net energy Company share a vision of WBCSD Project: Energy Efficiency in Buildings 9 Byggmaterialdagen, Stockholm 3 April 2008

10 What is zero net energy? Buildings, as a whole, generate as much energy as they use over a year About the EEB Vision 10 Byggmaterialdagen, Stockholm 3 April 2008

12  Low awareness of environmental impacts & value of being green. Energy efficiency is not an investment criteria.  Lifestyles are not focused on energy efficiency  Lack of know-how and experience for green construction  Lack of financial instruments to reward energy efficiency  The building sector is complex, fragmented and with no real champions Energy Efficiency in Buildings Key findings of the progress report, Sept. 2007 12 Byggmaterialdagen, Stockholm 3 April 2008

13 Life cycle energy use 13 Byggmaterialdagen, Stockholm 3 April 2008

14  The EEB study is built on data from countries representing 2/3 of world energy demand  This reflects more than 100 billion square meters of building floor space  Conclusion: Know-how & technologies available today to drive down world energy demand & reduce carbon emissions WBCSD Energy Efficiency in Buildings Project 14 Byggmaterialdagen, Stockholm 3 April 2008

15 A complex sector Fragmentation in design and delivery acts as a barrier 15 Byggmaterialdagen, Stockholm 3 April 2008

17 Environmental impact underestimated 17 What percentage of CO 2 emissions do you think buildings give rise to – directly and indirectly?

18 Costs overestimated 18 How much do you think a certified sustainable building would cost to build relative to a normal building?

21 Encouraging interdependence with a holistic approach 21 Integrated Design process: Involves all participants in early design phase of the project Benefits of early integration Byggmaterialdagen, Stockholm 3 April 2008

22 Three approaches in a supportive framework 22 Byggmaterialdagen, Stockholm 3 April 2008

23  A holistic approach requires integration of all parts of the urban infrastructure  WBCSD work based on projects for buildings and mobility Urban Infrastructure 23 Byggmaterialdagen, Stockholm 3 April 2008

24 Buildings can make a major contribution to tackling climate change and energy use: Now is the time to act 24 Consequence Byggmaterialdagen, Stockholm 3 April 2008
