CLEAN CONSTRUCTION PROGRAMME
Why does construction matter? Co Constr tructi tion contributes mo more th than 23 23% of of gl global GH GHG em emis issio ions ns (Huang et al., 2017) By 2025 we will need to build 1 bi billion ne new ho homes . Globally, 60 60% of of bu buildings th that wi will ex exist in in 2050 2050 ar are ye yet to to be be bu built. This is equivalent to constructing a ci city th the si size of of Stoc St ockhol olm or or Mi Milan (1.5 mi million pe peopl ople) pe per we week until 2050; a city the size of Sin Singapor pore or or Ne New Yo York ev every mo month unt until 2050 2050 . Beijing Daxing International Airport construction Construction materials and the building sector are responsible for more than 30 30% of of gl global re resource cons co nsum umption. Construction sites cause si significant ai air an and no noise pol pollution ion, linked to construction activities, the use of diesel machinery, lorry movements, and traffic congestion. 12 Winds stirring up construction site dust in Beijing
Cement, concrete and steel impact industry accounts for 8% of The cem cement ent in of th the world’s ’s em emis issio ions ns , and for 90% of the concrete industry emissions “After water, concrete is the most widely used substance on Earth” The Guardian The steel industry is responsible for at least 7% of of gl global em emis issio ions ns, and global consumption is ex expected to to do double by by 2050 2050 13

Clean Construction Forum - scope Cl Clean Co Constr tructi tion is about tackling the invisible emissions of buildings and infrastructure during their whole life Embodied E Emissions 20 to 50% of a building whole-life emissions “Embodied carbon is the sum impact of all the greenhouse gas emissions attributed to the materials throughout their life cycle (extracting from the ground, manufacturing, construction, maintenance and end of life/disposal).” Carbon Leadership Forum at the University of Washington 15
