Achieving net-zero carbon emissions in construction supply chains - A multidimensional analysis of residential building systems

• The construction sector accounts for approximately 25% of global CO2 emissions. In this paper, we provide a multidimensional assessment of the potential for greenhouse gas emissions abatement in relation to the construction of multi-family residential buildings. Different building designs are compared, whereby the study analyzes the potential reductions in greenhouse gas emissions when combining abatement measures with a perspective of the technologies and practices available now, and those that are likely to become available on a timescale up to Year 2045. Further, the assessment analyzes the potential for emissions reductions when applying abatement measures at different points in the supply chain, from primary material production via material composition to the final building structure. The results indicate that the greenhouse gas emissions can be reduced by up to 40% with currently available technologies and practices, with even greater potential reductions of 80% to Year 2030 and 93% to Year 2045.
