The built environment is responsible for approximately 40 per cent of the total energy related greenhouse gas emissions, of which around 28 per cent is operational carbon and 11 per cent from embodied carbon. While increased use of greener energy sources and increased efficiencies are driving operational carbon reduction, the focus needs to shift to embodied carbon, which is irreversible in nature and is locked in once the capital asset is built.
KPMG Embodied Carbon Management System is a Building Information Modeling (BIM) based platform enabling analysis of embodied carbon footprint for optimisation in capital projects through measurement; multi-scenario analysis by leveraging design strategies for carbon reduction, carbon supply chain tracing; and focusing on carbon hotspots for targeted reductions.
The platform seamlessly integrates the design and supply chain data with a set of repositories containing material emission factors, transportation factors and environmental product declarations by manufacturers to carry out the assessment. The project emissions can then be visualised within the design through carbon hotspots enabling concentrated efforts to reduce emissions. The decision-making process is further aided by alternative and green material suggestions with cost-carbon trade off simulation.
Carbon dashboards derived from the evaluation enable a consolidated at-a-glance view of project carbon KPIs allowing:
- Comparison of parametric carbon intensities with industry benchmarks
- Visualisation of material-wise supply chain emissions
- Optimisation iteration comparison and carbon build up across construction timeline
- Cost carbon trade-off.
