Webinar 34 | CReDiT - Carbon reduction tools to support sustainable remediation and earthworks on brownfield sites

Brownfield remediation typically involves major earthwork movements, the use of rapidly reducing resources (topsoil) and the potential reuse or disposal of large quantities of contaminated material. The remediation process and development frameworks are not optimised for achieving sustainability targets, often favouring cost and time-savings over carbon reduction.    There is, therefore, a need to optimise brownfield remediation to significantly reduce the carbon footprint of the process.

This issue was addressed through a collaborative project between the University of Surrey and LEAP Environmental to develop a carbon tool to evaluate the carbon dioxide generated from different site remediation options. This tool promotes greater understanding of the impact of remediation processes on carbon emissions and sustainable site material use.  CReDiT was developed for the dominant remediation method used on residential sites within the UK, namely excavation and cover. This tool determines carbon emissions from the processes involved in this type of remediation, e.g.…
