UK auto industry warns anti-diesel agenda and slow uptake of EVs could mean missing 2021 CO2 targets; rising CO2 average in 2017

Green Car Congress

The UK automotive industry warned that the current anti-diesel agenda combined with the ongoing slow take-up of electric vehicles could mean industry misses its next round of CO 2 targets in 2021, with negative consequences for the UK’s own climate change goals. However, this increase was not enough to offset a -17.1%

ICCT: decline in diesel sales will have negligible impact on attainment of European CO2 emission standards

Green Car Congress

The current decline is ales of diesel light duty vehicle in Europe does not put EU CO 2 targets out of reach of automakers, according to a new analysis by the International Council on Clean Transportation (ICCT). In addition, vehicle manufacturers increasingly use electric motors to complement conventional combustion engines in cars.
