Chidi Ochem conducted a sustainability audit to determine Harris County Precinct One Fleet Division Carbon Footprint and proposed a policy framework for electric vehicle adoption.
Harris County Precinct One's Fleet Division proposed to reduce its carbon emissions by 40% by the year 2030, develop metrics to determine when to retire old heavy-duty/high-occupancy vehicles to replace them with zero-emission vehicles (ZEV), and develop electric vehicle (EV) policy.
Chidi Ochem was enlisted to conduct a sustainability audit to determine the carbon footprint of the Fleet Division, define metrics to retire the old fleet and replace them with ZEV, and develop a policy for EV adoption.
Chidi used a four-part technique to conduct the sustainability audit and metrics to retire and replace the old fleet with ZEV.
- Fleet categorization: After site visits and fleet identification, fleets were categorized into Light, Medium and Heavy-Duty Vehicles.
- Data collection: Data was collected from site visits, stakeholder interviews, fleet annual fuel consumption, cost of maintenance, and distance traveled.
- Data analysis: Using the EPA simplified GHG calculator and AFLEET tools, the carbon footprint was calculated to be 1,441 MTCO2e (Total CO2 Equivalent Emissions).
- The LDVs carbon footprint was very low when compared to the average emissions of the same class of vehicles.
- The MDVs carbon footprint was moderately okay, while the HDVs were high.
- Total cost of ownership: TCO analysis was employed to determine metrics for retiring old fleets and replacing them with ZEVs.
The result of the audit provided a guide towards achieving the set targets.
- Monthly carbon footprint tracking: Using the emissions factors for both gallons of gasoline/diesel consumption and distance traveled, Chidi developed a model to track the fleet division's monthly carbon footprint.
- Metrics for retiring old fleet and replacing them with zero emission vehicles: The total cost of ownership (TCO) model was employed using the AFLEET and DRVE tools to determine metrics for retiring the old fleet and replacing them with zero emission vehicles.
- Electric vehicles and infrastructure deployment: Various models of available electric vehicles in the market and charging infrastructures were recommended for replacement and adoption.
- Electric vehicle (EV) policy: Based on the result of the sustainability audit, Chidi developed EV policy for Precinct One and made recommendations for its implementation.
