Annex 55: Real Driving Emissions and Fuel Consumption

Purpose and Objectives

This project aims to develop an emission rate, fuel consumption and energy efficiency inventory of vehicles driven on-road in varying countries in typical seasonal corresponding climates, fuelled with advanced, renewable and conventional fuel. Vehicle performance will be investigated over typical regional driving conditions such as city, highway, arterial, free-speed, and congested routes.

In short the objective of this project is to explore the real driving emissions (RDE) and real-world performance of vehicles operating under a range of worldwide driving conditions.

This study will provide an understanding of how different vehicle configurations including advanced and renewable fuels perform in on-road experiments. This data is to be used to inform policy decisions and will be provided to researchers for use in refining models, enhancing other inventories, and performing secondary research.


The activities to be undertaken will be divided into two phases:

Phase I:

  • Study/review of ongoing real driving emissions (RDE) activities in different parts of the world
  • Literature review and evaluation of different methods and technologies used for RDE. This will include an evaluation of different PEMS (Portable Emissions Measurement Systems) along with an evaluation of different driving conditions, types of vehicles (light duty and heavy duty) to be evaluated. Existing or upcoming legislation concerning the thresholds for boundary conditions (e.g. max/min temperatures, altitude, fuel specification,…) as well as corresponding evaluation methods shall also be analyzed to identify which data sets can be compared and to elaborate a common “best practice” protocol for a measurement program in phase II.

Phase II:

  • Conduct emissions and energy efficiency measurements which will include
    • Different fuel specifications such as advanced and renewable fuels
    • Regionally adopted driving cycles
    • Ambient temperature variations
    • Inclusion of cold start emissions
    • and in some cases a comparison to regulatory cycle emissions and efficiency

Expected Results/Deliverables

It is expected that a sub report will be provided for Phase 1 by mid-2016. A detailed test plan for each of the participating countries emissions and efficiency measurements will be provided during the third quarter of 2016 and measurements will be conducted during 2016 and 2017. Data analysis and reporting will be conducted during 2018. Also, the potential to conduct in-laboratory emissions tests will also occur during 2018.
