New emissions targets set by the European Union are forcing car manufacturers to think hard about how they'll lower average CO2 emissions across their fleets before the end of the decade.
According to figures produced by International Council on Clean Transportation (ICCT), the average CO2 emissions of new cars have fallen from 160g/km in 2006 to 132g/km in 2012, a drop of about 17 per cent.
Manufacturers must also comply with an average fleet rating of 130g/km by the end of next year, a target which most firms expect to meet. However, European rule makers have specified a target of just 95g/km by 2020.
A late tweak to the regulations means that only 95 per cent of new cars have to hit the 2020 targets. However, 100 per cent of new vehicles will have to comply by 2021.
The drop from the 2015 target to the 2020 target is an average reduction in fuel consumption of about 27 per cent, something that will clearly be a challenge for all manufacturers.
The 95g/km average doesn’t apply exactly to each manufacturer. Each brand has its own target, because the CO2 target figure is calculated by taking into account the average weight of a brand’s vehicles.
