3.9 Most vehicles will continue to be allocated an NEDC fuel consumption figure which may be derived by computer simulation rather than tested, as well as a WLTP figure, until 2021, for the purposes of CO2 fleet monitoring. This leads to the possibility of confusion for the public, in both fuel consumption and taxation.

3.10 There needs to be a transition from NEDC to WLTP derived figures for both fuel consumption and CO2 emissions. This consultation seeks views on the best way to manage the transition from NEDC to WLTP.

Fuel consumption changeover

3.11 We are proposing to require manufacturers to change all of their published information on Fuel Consumption from NEDC to WLTP on 1 January 2019. This will not apply to vehicles without WLTP testing figures, for example manufacturers selling off limited quantities of old stock tested only to NEDC.

...

Specific CO2 emissions changeover

3.15 We are proposing to require manufacturers to change all of their published information on the Specific CO2 emissions from NEDC to WLTP on 6 April 2020. This will not apply to vehicles without WLTP testing figures, although there will be very few of these by this date. All consumer information including government and third party publications should also use these official figures from this date.

3.16 The CO2 figure is used to determine First Year Vehicle Excise Duty (VED) and company car (Benefit in Kind) taxation. The Treasury announced in the recent 2017 Budget that from 6 April 2020, the basis for calculating these taxes will change to the CO2 figure derived from the WLTP cycle. That being the case, we would propose that the consumer-facing CO2 figure provided alongside fuel consumption information on labels or posters should change to WLTP on the same day, although of course both sets of information will be available to those who need them on manufacturers' websites. If WLTP figures are provided for comparison before this proposed date, or NEDC after this date, the provider should ensure that they are clearly marked as such.

Larger new cars are ‘less green’ than older vehicles, despite motor industry claims they are backing efforts to combat global warming. Which found the latest generation of cars emit more CO2, which is associated with climate change the reason being new vehicles in almost every category tend to be heavier than their predecessors. One of the reasons being that manufacturers have installed new devices to cut exhaust emissions that are harmful to human health, such as nitrogen dioxide.
Mid-size petrol SUVs, which covers vehicles of the size of the Nissan Qashqai, rose by 20.4 per cent – up from 157.6g/km to 189.8g.

Heavier new cars pump out more CO2 than older models : https://mol.im/a/8053353
