Newark and Sherwood District Council Fleet Review

Case Study

The Challenge

Newark and Sherwood District Council (N&SDC) requested that Cenex undertake a strategic review of their long-term ambition to operate a fully zero tailpipe emission vehicle fleet.

The study aimed to identify the immediate opportunities for N&SDC to adopt ultra-low emission vehicle (ULEV) technologies within the Environmental Services and Housing fleets by assessing their operational suitability, total cost of ownership and emissions under the current fleet conditions.

Given that the fleet included large vans and heavy goods vehicles (HGV), the review also included low emission vehicle (LEV) technologies that can reduce greenhouse gas emissions (e.g. renewable fuels) in difficult to electrify vehicle segments.

The Development

Low Emission Vehicle Fleet Review

  • Baselining of current fleet composition and emissions performance
  • ULEV and LEV technology screening to highlight those technologies which have the potential to provide emissions improvements at an equivalent or reduced total cost of ownership
  • Assessment of the operational suitability, total cost of ownership and emissions of selected ULEV and LEV technologies
  • Recommendations for the most suitable LEV technology for each vehicle
  • Development of an indicative LEV replacement schedule

Infrastructure Requirements Review

  • Assessment of number and type of chargepoint required to support charging of identified replacement electric vehicles
  • Quantification of the total energy required to charge electric vehicles
  • Information on types, specification and costs of electric vehicle charging infrastructure
  • Constrained power supply guidance

The Results

  • Battery Electric and Bio-CNG vehicles were identified as suitable alternatives for segments of the fleet.
  • The remaining vehicles were identified as being appropriate for the use of lower emission alternative fuels such as FAME and HVO.
  • The identified replacement vehicles would save around 3,900 tonnes of WTW CO2 emissions (based on the current UK grid mix and the use of biomethane only), 1,000 kg of NOx and 1.6 kg of PM.
  • These environmental savings can be achieved at no additional total cost of ownership.
