Reaching the ambitious objectives set for reducing CO2 emissions by 2030 is dependent on:

  • vehicle electrification
  • as well as a significant improvement in IC powertrains using environmentally-friendly fuels in such a way as to:
    • make clean, efficient technologies accessible to all usages,
    • progress towards ever greater hybridization as a function of application type,
    • target IC engines with a high average efficiency and near-zero emissions.

Three principal objectives to address these challenges:

1 - Significantly improve the thermodynamic efficiency of IC powertrains:

  • via the optimization of existing or emerging technologies,
  • as well as the introduction of disruptive solutions,
  • while maintaining a simple and effective pollution control system across its operating range.

« We are targeting a gasoline engine with a peak efficiency of 50% before 2030. This represents an efficiency gain in excess of 2%/year, i.e., a contribution of close to -20 gCO2/km by 2030. »

2 - Achieve levels of pollutant emissions affecting air quality approaching zero in real usage conditions and throughout a vehicle’s lifespan, focusing on three priority areas:

  • the development of innovative after-treatment systems,
  • the accurate assessment of the impact of emissions on air quality,
  • the real-time control of pollutant emissions.

« By 2030, we need to have access to technological solutions enabling the use of an IC engine in urban settings without impacting air quality. »

3 - Identify fuels with a double impact to reduce CO2emissions:

  • due to their non-fossil origin,
  • and thanks to their favorable properties in terms of increasing engine efficiency.

« For example, the use of 20% bio-based natural gas, would lead to a reduction in fossil CO2 emissions of around 50 gCO2/km. »


The share of oil-based fuel in the transport sector will remain significant in the coming years, at more than 80% out to the year 2040 (source BP).


Bringing innovative technological solutions in order to reduce the fuel consumption and CO2 emissions of IC powertrains and improve air quality.
