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

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

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

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

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

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

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?
