What is 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
