Clean car, the myth of technological measures

Technological measures and the myth of the clean car.

The reduction of unit CO2 emissions thanks to technological improvements is played out at several levels: the engine and fuels of course but also aerodynamics, weight, rolling resistance, braking energy recovery, fuel consumption. accessories, etc. and manufacturers and engineers regularly promise us “clean” vehicles in the near future. This qualifier, somewhat overused, applies poorly to the issue of climate change. Because, if scientific and technological advances do exist, their record with regard to greenhouse gases is mixed. In any case, reading the figures, it is difficult to see how technology alone could solve the problem. The new PNLCC measures that can be classified in the “technological improvements” category only account for 7% of the reduction effort to be made (PNLCC objective: - 4 MteC for 2010).
