4、sessment to Action:A Spotlight on Whole Life Carbon Processes in CitiesIIForewordGlobal CO2 emissions from buildings have stabilized(at a high level of ca.14Gt per year,or almost 40%of total emissions)but we are not yet seeing the necessary steep decline that would bring us within reach of keeping g

5、lobal warming to between 1.5-2C.While ca.70%of these emissions are related to the energy used to heat,cool and run buildings(operational carbon),another 30%are due to the production emissions of construction materials(embodied carbon).We need to address both operational and embodied carbon emissions

6、 in conjunction,and we need to urgently work toward halving emissions from new construction by 2030 and deeply retrofitting the existing inefficient building stock(while not adding new embodied carbon).This is why the implementation of Whole Life Carbon processes is critical,as it allows us to under
