On 31 May, the national standardisation bodies voted to approve a new ISO standard for extracting trip data out of nomadic and mobile devices for estimating fuel consumption and CO2 emissions. The original project was introduced by the national standardisation body of Belgium in close cooperation with ERTICO and project partners from the EU-funded projects CO-GISTICS, AEOLIX, 5G-LOGINNOV and FENIX Network.
The Technical Committee ISO/TC204 and its Working Group 17 on Nomadic Devices in Intelligent Transport Systems approved the new project, which describes the procedure to extract speed profiles from mobile devices and compares them to established Driving Cycles such as the Worldwide Harmonized Light Vehicles Test Procedure (WLTP). In several field tests executed across Europe, the resulting measurement values in [%] of fuel and CO2 relative to WLTP proved to be reliable, within tolerable error rates, and enabled fleet and traffic managers to estimate and reduce the impact of fuel and CO2 per trip.
“The approved ISO 23795-1 standard represents a great achievement of FENIX Network project. It demonstrates again for the project its unique role as incubator for innovation in transport and mobility. This is a key milestone for the involved projects and a clear appreciation for ERTICO’s effort supporting the European Commission Green Deal initiative,” remarks Joost Vantomme, CEO of ERTICO-ITS Europe.
The advantage of the proposed new ISO 23795-1 procedure lies in its flexibility due to the huge number of mobile devices existing in the worldwide Smartphone market. Importantly, fuel consumption and CO2 emissions can be evaluated by any type of mobile device using the speed profiles from satellite receivers. This enables fleet managers and drivers to better understand the impact of certain driving manoeuvres, thus supporting eco-drive, where they can improve tour planning by analysing the carbon footprint per trip rather than by checking fuel bills each month. Further details of the procedure can be found in: ISO standard ISO 23795-1:2022 “Intelligent transport systems — Extracting trip data using nomadic and mobile devices for estimating CO2 emissions — Part 1: Fuel consumption determination for fleet management”.
“This standard specifies a method for the determination of fuel consumption and resulting CO2 emissions to enable fleet managers to reduce fuel costs and greenhouse gas (GHG) emissions in a sustainable manner. By sending speed profiles from the global navigation satellite system (GNSS) receiver of a nomadic device via mobile communication to a database server and by calculating the deviation of the mechanical energy contributions of: a) aerodynamics, b) rolling friction, c) acceleration/braking, d) slope resistance, and e) standstill, relative to a given reference driving cycle in [%], an easy-to-use tool for carbon footprint monitoring per trip is now available and ready for APP store marketplaces,” says Ralf Willenbrock, FENIX Network project manager at Deutsche Telekom subsidiary T-Systems contributing to standardisation within his project work.
As the mechanical energy consumption of the reference cycle is known by measuring a set of static vehicle configuration parameters, the methodology enables drivers, fleet managers or logistics service providers to calculate and analyse fuel consumption and CO2 emissions per trip by simply collecting trip data with a GNSS receiver included in a Nomadic Device (ND) inside a moving vehicle. In addition to the on-trip and post-trip monitoring of energy consumption (fuel, CO2), the solution also provides information about eco-friendly driving behaviour and road conditions for better ex-ante and ex-post trip planning. Therefore, the solution also allows floating cars to evaluate the impact of specific traffic management actions taken by public authorities with the objective of achieving GHG reductions within a given road network. The ND is not aware of the characteristics of the vehicle.

“The approved ISO-23795-1 standard will now allow companies and market players to develop further applications based on the proposed methodology and to reduce CO2 emissions and fuel costs worldwide, urgently needed on the political agenda towards low carbon mobility solutions,” add Mr Willenbrock.
“All future investment has to prove sustainability indicators, therefore transparent methodologies and robust tools for carbon footprint monitoring are needed to agree on how to measure them. Dealing with environmental mobility indicators, ISO-23795 will also support the European Commission Green Deal initiative in order to achieve zero emission targets for 2050,” says Dr Eusebiu Catana, Senior Project Manager of Innovation & Deployment at ERTICO and Project Coordinator of the four projects involved.
FENIX Network project is co-financed by the Connecting Europe Facility of the European Union.
