SRF Optimiser

SRF Optimiser is a web-based decision support tool that calculates GHG emissions, energy consumption and costs associated with a company’s road freight transport operation. It models the effects of 29 carbon-reducing measures, the tool assesses the GHG, energy and cost implications of a range of technologies and management practices that can be applied to a transport fleet.

Benefits of using SRF Optimiser?

  • Know the carbon, energy and cost benefits of each carbon-reducing measures
  • Prioritise best carbon-reducing measures based on net present value
  • Analyse scenarios with actual and virtual fleet
  • Generate energy savings report to help with the requirements of ESOS
  • Track economic and environment benefits

Who should use it?

This tool can be used by any organisation, business or company that is involved in the road freight transport operations.

Benefits of using SRF Optimiser?

In order to generate reports, SRF Optimiser will need fleet information such as vehicle type, number of vehicles, number of tyres, transmission type, fuel type, fuel consumption (litres) and total distance (kms).
