Full title and description

STB BS ISO 23795-2-2024 — Intelligent transport systems — Extracting trip data using nomadic and mobile devices for estimating CO2 emissions — Part 2: Information provision for eco‑friendly driving behaviour. This document specifies how trip and driving‑behaviour data extracted via nomadic/mobile devices can be analysed and presented to drivers to promote eco‑friendly driving and reduce CO2 emissions.

Abstract

This part of ISO 23795 defines use cases (for events such as speeding, long speeding, sudden start/stop, sudden acceleration/deceleration, idling, fuel‑cut and economical driving), the functional requirements for collecting data to analyse driving behaviour patterns, and the data sets to be used for measuring vehicle CO2 emissions and for providing feedback to drivers via nomadic devices. The standard is intended for passenger cars, vans and similar light vehicles.

Scope

The standard specifies how to extract vehicle trip data via nomadic devices (for example GNSS data from mobile devices), which data elements are required to assess driving events and CO2 emission indicators, and how analysed information should be provided to drivers to encourage eco‑friendly driving behaviour. It covers the definition of use cases, the functional requirements for data collection and processing, and the data sets needed to estimate CO2 emissions related to specific driving behaviours for light vehicles.

Key topics and requirements

• Defined use cases for driving events (speeding, long speeding, sudden start/stop, sudden acceleration/deceleration, idling, fuel‑cut, economical driving).
• Functional requirements for collecting and processing trip and behaviour data from nomadic/mobile devices.
• Data set specifications for each use case needed to estimate CO2 emissions and to generate driver feedback.
• Guidance on information provision to drivers via nomadic devices (format and content of eco‑driving feedback).
• Applicability to passenger cars, vans and similar light vehicles; intended for on‑trip and post‑trip analysis scenarios.

Typical use and users

Used by telematics and software developers, nomadic‑device (mobile app) vendors, vehicle OEMs and subsystem suppliers, fleet managers, mobility service providers, and transport authorities interested in measuring and reducing vehicle CO2 emissions and promoting eco‑driving. Fleet analytics and eco‑feedback applications integrate these data and requirements to provide actionable driver guidance.

Related standards

ISO 23795 is a multi‑part series. See ISO 23795‑1:2022 (Part 1 — Fuel consumption determination for fleet management), which defines fuel‑consumption and CO2 estimation methods using trip‑data extraction and is directly related to Part 2's focus on information provision for eco‑friendly driving behaviour. Other ITS and vehicle‑emissions standards and national adoptions (e.g., BS ISO 23795‑2:2024) are commonly referenced together.

FAQ

Q: What is this standard?

A: ISO 23795‑2:2024 (adopted as national variants such as BS ISO 23795‑2:2024 / STB BS ISO 23795‑2‑2024) is an international standard that describes how to extract trip data using nomadic/mobile devices to estimate CO2 emissions and how to provide analysed information to drivers to support eco‑friendly driving.

Q: What does it cover?

A: It covers use cases for driving events, the functional requirements for collecting and processing trip and behaviour data, and the specific data sets needed to estimate CO2 emissions per use case and to present eco‑driving guidance to drivers.

Q: Who typically uses it?

A: Telematics and mobile app developers, vehicle systems suppliers, OEMs, fleet managers, mobility service providers and transport authorities — any organisation building tools to measure trip emissions or to deliver eco‑driving feedback.

Q: Is it current or superseded?

A: It is current (published in 2024). There is no indication of supersession as of its publication; users should check their national standards body for any later amendments or national forewords.

Q: Is it part of a series?

A: Yes — ISO 23795 is published in parts. Part 1 (ISO 23795‑1:2022) addresses fuel consumption determination for fleet management, and Part 2 (this document) addresses information provision for eco‑friendly driving behaviour. Additional parts or related ITS emission documents may exist or be developed.

Q: What are the key keywords?

A: ITS, nomadic device, trip data, CO2 estimation, eco‑driving, telematics, driving events, fleet management.
