This guide explains the insights you can draw from Fuel & CO₂ Optimization report and begin to improve your fleet’s efficiency and reduce emissions.
Fuel usage
1. Avg. fuel efficiency (km/L)
The average fuel efficiency per vehicle for the selected fleet/teams over the chosen date range, measured in kilometers per liter (km/L). This includes both diesel, gas and hybrid vehicles (see “Emissions data for ESG reporting” for details). Higher values indicate better fuel economy. The chart visualizes daily fluctuations.
2. Avg. fuel efficiency (L/100km)
The average fuel efficiency per vehicle for the selected fleet/teams over the chosen date range, measured in liters per 100 km (L/100km). This includes both diesel, gas and hybrid vehicles (see “Emissions data for ESG reporting” for details). Lower values mean better efficiency. The chart highlights daily changes.
3. Total fuel usage
The total fuel usage by the selected fleet/teams over the chosen date range, measured in liters (L). This includes both diesel, gas and hybrid vehicles (see “Emissions data for ESG reporting” for details). The main value represents the sum of all days in the selected range. The chart breaks down daily fuel totals.
Using the numbers 💡
Compare fuel efficiency (km/L or L/100 km) with total fuel usage to understand whether increased consumption is due to inefficiency or simply higher vehicle activity. If fuel efficiency declines while total fuel usage remains stable, it may indicate poor driving habits, vehicle wear, or increased idling—check the idling section to confirm.
A sharp increase in total fuel usage alongside higher total distance suggests that fleet activity has increased rather than efficiency dropping.
Electricity usage
1. Avg. EV Efficiency
The average energy consumption for the selected fleet/teams over the chosen date range, measured in kilowatt-hours per 100 km (kWh/100 km). Lower values indicate better efficiency. The chart shows daily variations.
2. Total EV Energy Used
The total electricity consumption over the selected date range for the chosen fleet/teams, measured in kilowatt-hours (kWh). The main value is the sum of all days in the range, while the chart breaks down daily energy usage.
Using the numbers 💡
Compare EV efficiency (kWh/100 km) with total EV energy usage to assess if higher energy consumption is due to increased EV use or reduced efficiency. If EV efficiency worsens (higher kWh/100 km) without a proportional increase in distance traveled, consider factors like battery degradation, extreme weather conditions, or inefficient driving habits.
Fleet managers transitioning from ICE to EVs can use this section alongside CO₂ emissions to track the environmental impact.
Distance
1. Avg. daily distance
The average daily distance per vehicle for the selected fleet, team(s), or vehicle group over the chosen date range. Measured in kilometers. Including the number of vehicles contributing to the data. The chart highlights daily variations.
A lower average could indicate underused vehicles or decreased demand, while a higher average might suggest overworked vehicles or potential inefficiencies. By understanding these trends, you can redistribute workloads or optimize route assignments to ensure the fleet operates efficiently.
Monitoring distance trends will also help explain changes in CO₂ emissions and identifies whether reductions are due to operational efficiency, vehicle transitions, or cleaner energy usage.
3. Total distance (km)
The total distance traveled over the selected date range for the chosen fleet, team(s), or vehicle group, measured in kilometers. The main value is the sum of all days in the range, while the chart shows daily totals.
This data can inform decisions about preventive maintenance schedules and whether your fleet size is appropriate for current demand. Significant increases in total distance highlight the need to plan vehicle servicing to prevent downtime.
Using the numbers 💡
Avg. daily distance per vehicle helps understand how much each vehicle is being used, while total distance gives an overview of fleet activity. If distance drops but fuel usage remains high, it may indicate idling issues or lower efficiency—check the idling and fuel efficiency cards to validate.
Sudden spikes in total distance could indicate seasonal demand changes, route inefficiencies, or an increase in active vehicles.
Idling
Please notice that we currently only collect idle time from ICE vehicles.
1. Avg. daily ICE idling
The average daily ICE idling time per vehicle (EV idle time is disregarded) for the selected fleet/teams over the chosen date range, measured in days, minutes and seconds (dd:hh:ss). Idling is recorded when a vehicle remains stationary with the engine running, filtering out brief stops like red lights. The chart tracks daily variations.
Excessive idling can indicate inefficiencies, such as prolonged waiting times, traffic congestion, or unnecessary engine use. Consider educating drivers on reducing idle time, and analyze routes for congestion-prone areas to implement alternative plans.
2. Total ICE idling
The total ICE idling time for the selected fleet/teams over the chosen date range, measured in days, minutes and seconds (dd:hh:ss). The main value is the sum of all days in the range, while the chart highlights daily trends.
Use total idling time to track fleet-wide trends and identify areas for improvement. For instance, investigate if certain vehicles or locations consistently contribute to higher idling times. Reducing idling not only saves fuel or energy but also lowers emissions and operational costs.
What to look for 💡
High idling time per vehicle can contribute to poor fuel efficiency. Compare idling trends with fuel efficiency to identify opportunities for improvement. If total idling is high but distance is low, drivers may be spending excessive time waiting with engines running. Consider reviewing route efficiency or driver behavior.
A fleet-wide reduction in idling time can lead to fuel savings and lower CO₂ emissions—monitor how idling trends impact fuel usage and emissions.
CO₂ Emissions
1. Daily CO₂ emissions
The average CO₂ emissions per kilometer for the selected fleet/teams over the chosen date range, measured in grams CO2 per kilometer (g CO2/km). The chart differentiates emissions from internal combustion engine (ICE) vehicles and electric vehicles (EVs), alongside the fleet-wide average. Lower values indicate reduced environmental impact.
2. Total CO₂ emissions
The total CO₂ emissions for the selected fleet/teams over the chosen date range, measured in kilograms (kg). The main value sums up all emissions across the date range, while the chart breaks down daily trends.
Pro tips 💡
Compare CO₂ per km with total CO₂ emissions to see if changes in emissions are due to efficiency gains or just lower fleet activity. If total CO₂ emissions drop, but CO₂ per km stays the same, it likely means the fleet is driving less, not necessarily improving efficiency.
EV usage can significantly lower emissions—compare ICE and EV trends in the emissions chart to track the impact of electrification efforts.
