Ending the cheating: using real-world CO2 measurements within the post-2020 CO2 standards
The biggest failure of the current car CO2 has been the failure to deliver emissions reductions on the road. Whilst new car CO2 emissions measured using the obsolete laboratory test (NEDC) have fallen by 31% since 2000, on the road the reduction is just, 11%. The gap between test and real-world performance has leapt from 9 to 42% weakening the regulation, increasing CO2 emissions and raising fuel bills for drivers. The underlying issue was basing the regulation on laboratory tests. Whilst the new WLTP addresses some loopholes, its introduction also creates new flexibilities that the car industry are planning to exploit to undermine both the current regulation to 2020/1 and proposed future regulations for 2025/30.
