Carbon dioxide (CO2) emissions and energy consumption
CO2 is the main culprit behind the greenhouse effect that threatens climate change. In consuming corresponding amounts of fossil fuel, motor vehicles release large amounts of CO2 into the atmosphere.

Renault pursues a number of major research initiatives to reduce these emissions.

  • To start with, Renault strives to minimize CO2 emissions from its gasoline and diesel engines. This problem is tackled from many different angles, including optimized fuel combustion, lightweight vehicle design, and reducing friction between moving parts. Improvements in all these areas help reduce fuel consumption, and thereby CO2 emissions.
  • Vehicle aerodynamics also has a bearing on fuel consumption. Recent developments in digital aerodynamic modelling provide engineers with valuable insights into the impact of design choices on fuel consumption.
  • Renault takes part in ambitious research programs on alternative energies capable of eventually taking over from classic petroleum fuels, either in the near future (for biomass fuels and battery-electric vehicles) or within a longer time-frame (for fuel cells to power electric vehicles).
