Why does construction matter?

Co Constr tructi tion contributes mo more th than 23 23% of

  • f 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

  • f 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

Cement, concrete and steel impact

The cem cement ent in industry accounts for 8% of

  • f 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

  • f

Clean Construction Forum - scope

Embodied E Emissions 20 to 50% of a building whole-life emissions

Cl Clean Co Constr tructi tion is about tackling the invisible emissions of buildings and infrastructure during their whole life “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).”

Carbone 4: our role in Reinventing Cities ?

Carbone 4’s role was to conduct the environmental assessment of each project regarding the 10 Challenges Carbon Impact Resilience & sustainability Inclusion & Social benefits

1. Energy efficiency and low-carbon energy (mandatory) 2. Life Cycle Assessment & sustainable materials management (mandatory) 3. Low carbon mobility 4. Resilience & adaptation 5. Ecological services & green jobs 6. Sustainable water management 7. Sustainable waste management 8. Biodiversity, urban revegetation & agriculture 9. Inclusive actions, social benefits and community engagement

  • 10. Urban design & quality architecture

Carbone 4: our role in Reinventing Cities ?

Carbone 4’s role was to conduct the environmental assessment of each project across 3 criteria:

Ambition level of the challenge objective Coherence between the solutions and the objective Use of rigorous methodologies and sources

Note: Different amount of each type of material are required for the same purpose. Steel for example has a very high kgCO2e/ton value, yet it is very strong so in most cases you need less of it than other materials. 866

Carbone 4: our takeaways

Over 65% of winners strived for carbon neutrality Winners included embodied emission solutions :

  • Construction materials: 50% of the

winners used wood, 50% used recycled/upcycled

  • Construction material origin: local,

low-carbon freight Big focus on incubators and green services that foster sustainable lifestyles

* * * * *

Carbon accounting methodologies were diverse and not always well understood.

  • All 3 carbon accounts should remain

separate : induced, avoided and negative.

  • The perimeter of a carbon footprint

has to be well defined : Building scope ≠ neighborhood scope Carbon neutrality was not always well understood : a net zero building includes both embodied and operational carbon. Areas of improvement Achievements
