DESCRIPTION:Only in the last three decades\, cement and plastic production
  has grown 2.5-fold\, glass 2 and steel 1.5-fold (Cullen J.M.\, Drewniok M
 .P. et al. 2020). In 2022\, the global building sector accounted for 34% o
 f energy demand and 37% of total energy related CO2 emissions\, reaching n
 early 10 Gt CO2 (Hamilton\, Kennard et al. 2024). More than a quarter wer
 e related to production of cement\, steel\, aluminium\, bricks and glass (
 embodied carbon). It is predicted that global building stock should almost
  double by 2050 to meet population growth needs (GABC and IEA 2017). In th
 e UK context\, the built environment already accounts for nearly 30% of th
 e UK’s total territorial GHG emissions (Green\, Jonca et al. 2021)\, wit
 h the main materials used in construction accounting for up to 6% (Drewnio
 k\, Azevedo et al. 2023). As demand for construction is expected to increa
 se (residential\, commercial\, non-emitting \ncarbon infrastructure)\, we 
 expect the use of materials to increase. \n\nEmissions reduction technique
 s during manufacture (e.g. using alternative fuels\, increase resource eff
 iciency in production) can only slightly reduce rather than entirely elimi
 nate the emissions related to construction materials.  Moving to the most 
 materially and carbon efficient technology options for buildings can bring
  further savings (Drewniok\, Azevedo et al. 2023) with the largest savings
  occurring in structural efficiency (Dunant\, Drewniok et al. 2021). Never
 theless\, this will not allow to reach net-zero carbon by 2050. It is ther
 efore crucial to minimise the overall flow of materials  in the UK constru
 ction – dematerialisation (Drewniok\, Azevedo et al. 2023). \n\nIn the p
 resentation we will try to analyse the extent to which dematerialisation s
 hould be implemented in the UK construction industry to minimise the emiss
 ions from UK construction.
