Green Freight Q&A

Almost 30% of all road freight mileage currently driven empty - Digitalisation is the key to Decarbonisation


How do FLS calculate carbon emissions?

FLS currently use a straightforward calculation of, the reported CO2 emissions per litre of fuel used for vehicle type booked, (DVLA Lookup) multiplied by the distance travelled on the delivery journey. This model will be evolved in the future to account for, weight of load and economy of journey type (Urban Vs Rural)

How do FLS calculate the savings made?

FLS model the Carbon saving made as the direct removal of the emissions incurred from the return empty mileage associated with road freight movements.
FLS consider this a conservative estimate as it only reflects the saving in return empty mileage and does not include the emissions reduced in the collection mileage, or oversized vehicles which are additional savings gained when utilising FLS.

Is the model accredited or recognised?

Accreditation of Road Transport Net 0 models are still very much in their infancy, especially in the UK. FLS are actively engaging with frameworks such as GLEC and are committed to pioneering such an accreditation model in the UK. In the meantime we stand behind our model and offer absolute transparency to our methodologies and data sources

Do FLS take into account the type of vehicle when calculating?

Yes. Vehicle type and size are core components of the FLS calculation model as Carbon emissions are calculated primarily by the grams produced from the burning of 1L of fuel. The fact that FLS are able source the most efficient sized vehicle for your load is another driver to the green nature of digital freight forwarders. As data becomes more readily available we will incorporate efficiency ratings and age of vehicle into our models

Do FLS take into account the weight of load?

FLS use a straightforward calculation of reported CO2 emission by vehicle type multiplied by distance travelled. This model will in the future evolved to account for variances weight of load makes on emissions

Do FLS take into account mileage to collection and back to point of origin?

Not in the current calculation, but it is anticipated the booker of the transport will be responsible for the emissions of all 3 legs. FLS model the Carbon saving made, as the direct removal of carbon responsibilities on the typical empty mileage associated with road freight movements (21.2%). FLS consider this a conservative estimate as it only reflects the saving in return empty mileage and does not include reduced collection mileage or return to the point of origin


Can a monthly overview on carbon emissions and savings be calculated?

Absolutely. FLS are able to report carbon emission and savings at the point of each booking. We can also aggregate this valuable data as part of our live business analytics package available on our FLS Client Portal.

How can customers reduce carbon emissions further by using FLS, what are the future plan?

The FLS model of reducing empty mileage by our data driven approach is already reducing your carbon footprint, however while our primary mission is to reduce empty mileage we will also be expanding our offering over the next coming years to reduce further carbon footprint reductions:

  • 2022 – Carbon weight measuring by vehicle and distance travelled
  • 2022 – Delivery of Client Carbon Dashboard
  • 2022 – Calculated saving against utilising a fixed origin haulier
  • 2022 – Installation of EV change points at Head office, Skewfields site
  • 2022 – Introduction of EV options in supplier fleet profile
  • 2023 – Accreditation of FLS carbon measuring model
  • 2023 – Launch of electric vehicles within our carrier network
  • 2024 – Launch of measuring fuel type, and usage of renewable biomethane fuel
  • 2024 – Enhanced CO2 saver modelling to include fuel type and considering electric vehicles
  • 2024 – Tools and programs released to the FLS carrier network to utilise for all work completed – creditably calculating and reporting emissions against industry standards
  • 2024 – Increased % of electric and Biomethane vehicles


A scalable haulage supply chain, managed and deployed by FLS technology led transport matching algorithms.

Utilising our Carrier Portal and drivers App, carriers can submit their availability status and empty journey commitments by exact location and times, enabling our planners to not only support scaled supply chain options for our customers but support our carrier in reducing their empty mileage, improving availability and their profitability.

Typically, in the logistics sector carriers can only provide you with a vehicle that’s available in their yard but using FLS and our transport matching algorithms running across our huge pool of carriers means we can select an available vehicle for your collection by proximity, not only do you get your vehicle on site quicker, but it has also of course produced fewer emissions getting to you.

With almost 30% of all road freight mileage currently driven empty, FLS mission is to reduce this. Our data driven approach sources and controls vehicles more efficiently, which enables shippers to benefit from the right size vehicle from the best location and essentially reduce empty mileage:

  • Intelligent transport allocation
  • Ai transport matching algorithms
    Select the closest carrier vehicle to the freight collection point. (Proximity not Haulier Origin)
  • Evaluate if that carrier can make another delivery on route to reduce empty miles
  • Choose the most fuel-efficient route to destination
  • After delivery, can we fill that vehicle with another load close by to bring them home or close to next collection point. (Return load)
    An empty journey means another vehicle is travelling alongside you with freight you could have been carrying.

    Lower miles = Lower fuel = Lower costs = Lower CO2

Environmental Care

Through intelligent load allocation, FLS make sure the vehicle selected for your collection has the least environmental impact as possible for the load you have - RIGHT VECHICLE FOR THE RIGHT LOAD

Time Critical - Green Freindly

Through our Carrier Portals transport matching algorithms we secure closest available vehicle to collection not the closest Carrier by origin.
