So now let’s get China in the mix... Will Cambridge Retrofit make the world’s emissions decline? Why is the red line, and not the blue line, achieved globally? 60 50 Gt CO2/year Coupled nations 40 30 Uncoupled nations 20 10 0 0 20 40 60 Year since 1990 80 100 120 What happens globally happens nationally… Who should pay for low carbon credentials of construction in China? Finally, let’s go to the US... The US and LEED… Why is there such a potential mis-match between certification level and performance? Hint: mix-and-match points system, and MCA The solution: sliding points scale… The US and LEED… And before we Brits get smug... The problem is equally bad for Energy Performance Certificates Some conclusions We will not meet global climate targets unless the developed nations help the developing bring low carbon practices on board Coupled economies are causing significant global leakage effects; LCA can help with this However, LCA does not help with the macroeconomic multiplier effect Production-based accounting will be supplemented by consumption –based; again, LCA helps in this Aspirations and performance of buildings is not well served at the moment by certification systems (but it is improving) Contact me… Douglas Crawford-Brown [email protected] (0)1223 760550 www.4cmr.group.cam.ac.uk Now a break, and then… ...we will determine where our retrofit efforts should focus in Cambridge
