Carbon accounting of hydraulic engineering schemes

Driven by ambitious carbon reduction targets of 80 per cent of 1990 emissions by 2050, EU/UK Government legislation and regulations now demand accurate accounting of carbon (or greenhouse gas) emissions. HR Wallingford is aware of this gap and this research project developed a scheme-based carbon accounting tool, HRCAT.

It has been acknowledged that the amount of carbon emitted by construction and maintenance of infrastructure (“scheme-based carbon footprinting”) is largely unknown and that consistent carbon accounting is needed (BIS, 2010).

HR Wallingford is aware of this gap and has developed capabilities in scheme-based carbon accounting which involved:

HRCAT allows a detailed estimation of carbon emissions, with an indication of associated uncertainty in the results, for a range of hydraulic construction schemes. This includes: coastal structures such as breakwaters and quay walls, river and coastal protection, and drainage systems including SuDS.

This will support sustainable option appraisal and feasibility studies, allow carbon accounts to be reported at detailed design stage, inform the development of specific construction components and provide an important new R&D tool.

The testing of the tool on real case studies has demonstrated that assessments of carbon emissions for construction schemes need to be carried out in considerable detail for transport and construction processes, as well as materials. Otherwise, the results can be at best uncertain and at worst misleading. This is due to the site specific nature of each construction scheme.
